| 摘要： | 曹廷杰（1850-1926）生於清朝末期，當時俄國勢力在東北擴張，他曾到東北及黑龍江等地實地考察，並記載當地民族、習俗、生物種類等，為晚清的東北、黑龍江等地留下珍貴的文化史料。他在光緒十一年（1885）四月奉命到伯力（今俄羅斯哈巴羅夫斯克）一帶勘查邊疆情勢，歷盡艱辛，往返一萬六千餘里。
他的論著《西伯利亞東偏紀要》以親身見聞並徵引群書，闡明黑龍江北岸、烏蘇里江東岸等地的中國領土及風土民情。文本記錄黑斤濟勒彌人等當地住民的生活習慣。東北盛產魚類，由於多數記載魚類使用當地民族語言，以致民國以後的研究者進行考證時，有部分文獻難以解讀，容易混淆。《西伯利亞東偏紀要》提到「東北海口有大魚，長一二丈大一二圍，其頭有孔如江豚涉波，孔窩中噴水高一二丈，訇然有聲，可聞數里。黑斤濟勒彌人通呼為麻勒特魚。」曹氏指出：「麻特哈魚，即遼、金史《本記》所載之牛魚也。」麻勒特魚或麻特哈魚究竟是什麼魚？
本文解讀曹氏著作，配合生物種類調查，認為麻勒特魚與麻特哈魚應指相同生物種類，且類似鯨豚類等海洋哺乳動物。當代有部分文獻將麻勒特魚解釋為鰉魚(Huso dauricus)，可能是受到清代之前的史書提及「牛魚」解釋的誤導。透過經庫頁島鯨豚類調查資料及盛行於東北之原始宗教薩滿教動物崇拜等民族學文獻比較，本文可推論出《西伯利亞東偏紀要》敘述的麻勒特魚，極有可能是現今的虎鯨(Orcinus orca)。 |

| 摘要： | The genes encoding skeletal muscle tropomyosin, with a unique coiled-coiled linear structure along the full-length molecule, were cloned from a wide range of fish species, and the deduced amino acid sequences, especially the amino acid substitutions between fish species from tropical to cold waters were discussed, based not only on the phylogenetic analyses but also on the species-specificity of thermodynamic properties as measured by calorimetric studies and thermal helical decaying profiles of the purified tropomyosins. The results obtained showed clear differences in thermal stability among the fish species examined, though the identity of amino acid sequences was higher than 92%. It suggests that only a few amino acid substitutions affect the overall stability of the tropomyosin molecules. Several residues especially located on the molecular surface were considered to be responsible for such stability difference. However, it was difficult to pinpoint the responsible residues. Thus it is likely that communications between the residues far from each other on the molecule exist. On the other hand, the molecular mass of these tropomyosins measured by mass spectrometry were generally higher than those calculated based on the deduced amino acid sequences, suggesting the presence of post-translational modifications which could also affect their thermal stability difference. |

| 摘要： | In order to investigate the species-specific heat tolerance of tropical fishes, the thermodynamic properties of muscle tropomyosin, a member of myofibrillar proteins, were compared among milkfish, tilapia, grouper, and mudskipper. The purified tropomyosins were subjected to differential scanning calorimetry and circular dichroism spectrometry. To unveil the relationship between the stability and the amino acid sequences, the muscle tropomyosin genes of the four species were also cloned, and their deduced amino acid sequences were compared. Thermodynamic analysis revealed that the milkfish tropomyosin showed lower refolding ability after thermal denaturation, compared with those of the other species. The amino acid sequences of these tropomyosins were similar to each other, with the identity being in the range of 95–96%. |

| 摘要： | In order to elucidate the phylogenetic relationship of fish, DNA and deduced amino acid sequences of myoglobin (Mb) were used for the phylogenetic analyses based on different approaches, namely, maximum likelihood (ML), neighbor joining (NJ), unweighted pair group method with arithmetic means (UPGMA) and maximum parsimony (MP) methods in comparison with the conventional molecular markers, mitochondrial cytochrome b (cyt-b) and cytochrome c oxidase subunit I (COI). The phylogenetic trees drawn based on Mb sequences were similar to those by the traditional classification based on the other molecular markers. The primary and secondary structures, as well as the modeled tertiary structures of Mbs were similar to each other, but were clearly distinguishable among those species. Such differences in structure would be associated with adaptation of Mb molecule to the physiological conditions of each species. These results suggest that Mb can be a molecular marker for the phylogenetic relationship of fish. |

| 摘要： | Abstract: Burnt meat is one of the unusual meats often occurring in tuna species. In order to reveal the biochemical properties of burnt meat in tuna, burnt meat and normal meat samples were collected to examine the quality parameter including pH, color parameters, lactic acid content, the activities of antioxidant enzymes, and the levels of thiobarbituric acid reactive substances (TBARS) and scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. The results showed pH was significantly lower in burnt meat than in normal meat, and the lactic acid content was generally higher in burnt meat. In color parameters, the L* and b* values were higher in burnt meat. Besides, the activities of antioxidant enzymes, namely, superoxide dismutase (SOD),glutathione reductase (GR) and catalase (CAT) in normal meat were higher than those in burnt meat. TBARS levels were significantly higher in burnt meat than in normal meat. It is thus likely that strong struggle of fish throughout catch and high water temperature induce partial inactivation of these antioxidant enzymes, resulting in free radical formation which triggers the occurrence of burnt meat. This fact could be beneficial for aquaculture and livestock industry of tunas to prevent burnt meat.

| 摘要： | The spawning ecology of the girellid fishes in Japanese waters has been reported almost only for Girella punctata, whereas little is known about Girella leonina. We examined sexual maturation of G. punctata and G. leonina collected from the coastal waters (neritic) of the Izu Peninsula and Tanegashima Island, based on gonadosomatic index (GSI) and gametogenesis, in order to clarify interspecific differences in spawning ecology. The GSI values of G. punctata in the Tanegashima Island region were markedly high in March, a month prior to the peak in April in the Izu Peninsula region. Girella punctata with elevated GSI had histologically mature ovaries and testes in spring in the both regions, suggesting spawning at this time of year. In contrast, the GSI values of G. leonina were much lower in the both regions, but the maximum GSI of both male and female G. leonina were slightly higher in the Tanegashima Island region than in the Izu Peninsula region. Furthermore, oogenesis in G. leonina was more advanced in the Tanegashima Island region. It is thus probable that Tanegashima Island is relatively near the spawning ground of G. leonina. |

| 摘要： | The complete mitochondrial genome of the gnomefish Scombrops boops was determined by a PCR-based method. The total length of mitochondrial DNA (mtDNA) was 16,517 bp, including 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and one control region. The mitochondrial gene arrangement of the gnomefish mtDNA was identical to those of typical teleosts. This is the first report of the complete mitochondrial genome of a member of the Scombropidae family and will be useful for the development of molecular tools for ecological research. |

| 摘要： | Neonatal hypoxic-ischemic (HI) encephalopathy can lead to severe brain damage, and is a common cause of neurological handicaps in adulthood. HI can be resolved by the administration of an antioxidant such as 3-methyl-1-phenyl-2-pyrazolin-5-one (MCI-186). In the present study, we performed comprehensive gene expression and gene network analyses using a DNA microarray to elucidate the molecular events responsible for the selective vulnerability of neurons in neonatal HI brain insult and to examine the underlying mechanisms of the effect of MCI-186 on the pathophysiological events in this condition. We used the modified Levine method (Rice model), which has been widely used as an animal model of this condition. A large difference in gene expression was observed between the Rice model and the control group. Up- and downregulated genes after the HI brain insult were mainly related to immune responses and cell death, and neuronal activity, respectively. The effect of MCI-186 administration on gene expression was much less than and contrary to that of the HI brain insult, reflecting the protective effect of MCI-186 in HI brain insult. |

| 摘要： | A few mutations in the gene encoding the gamma 2 subunit of the gamma-aminobutyric acid receptor type A (GABRG2) have been reported in various types of epilepsy. The aim of this study is to investigate the role of GABRG2 in the pathogenesis of childhood epilepsy in a large Japanese cohort. Genetic analysis of GABRG2 was performed on 140 Japanese patients with various childhood epilepsies largely including Dravet syndrome and genetic epilepsy with febrile seizures plus. The mutational analysis identified one novel missense mutation of GABRG2 (c.236A>G: p.N40S) in a patient with generalized tonic-clonic seizures (GTCS). The mutation was heterozygous and replacing a highly conserved Asn residue with a Ser. The affected amino acid was located at residue 40 of the mature GABRG2 protein, which was near the first one of two high-affinity benzodiazepine-binding domains of the γ2 subunit (Lys-41-Trp-82). This mutation in such an important position may hamper the function of the channel and contribute to the case’s pathogenesis of GTCS. |

| 摘要： | Fast skeletal muscle tropomyosin (TM) of tunas is composed of nearly equimolar amount of two isoforms designated α-TM and β-TM expediently based on their migration behavior in SDS–PAGE, whereas corresponding TMs from the other fish species are homogenous (α-type). The presence of β-TM is thus specific to tunas so far. The amino acid sequence of β-TM from bluefin tuna Thunnus thynnus orientalis, which has not been revealed to date unlike α-TM, was successfully obtained in this study by cDNA cloning. The coding region of β-TM cDNA comprised of an open reading frame of 855 bp encoding 284 amino acid residues, like most of the TMs. Unexpectedly, the sequence of β-TM showed high similarity to those of other vertebrate α-type TMs including tuna α-TM. Phylogenetic analysis also showed that β-TM has the closest relationship with α-TM of tuna. This fact was quite unlike the relation of mammalian α- and β-TMs. Based on the distribution of amino acid substitutions, it was suggested that tuna TM isoforms are the products of different genes. By thermodynamic analysis of native and reconstituted TMs, it was demonstrated that β-TM is less thermostable than α-TM. Proteolytic digestion also supported the lower stability of the former. |

| 摘要： | Evidence that some types of epilepsies show strong genetic predisposition has been well documented. AP3M2 is considered to be an epileptogenic gene because AP3M2 knockout mice exhibit symptoms of spontaneous epileptic seizures. In order to investigate whether the AP3M2 gene causes susceptibility to epilepsy, we performed mutation screening of the genomic DNA of 190 patients with six epilepsy types; this screening involved all the 9 exons and the relevant exon–intron boundaries of AP3M2. Although neither missense nor nonsense mutations were detected, we identified 21 sequence variations, of which 16 variations were novel. Of the 21 variations, 11 were detected in 5′ and 3′ UTRs, while the remaining variations were detected in introns. Although the present study failed to identify the possible AP3M2 mutations that may cause epilepsy, our results suggest that some AP3M2 mutations still remain candidates for unmapped disorders including epilepsy, febrile seizure, and other neuronal developmental disorders associated with functional abnormalities of GABAergic transmission. |

| 摘要： | Tropomyosin (TM) was isolated from the fast skeletal muscle of six fish species, whose amino acid sequences of this protein have already been revealed. The thermal stability of these TMs was measured by differential scanning calorimetry (DSC) and circular dichroism (CD), while the molecular weights were measured by mass spectrometry. The results showed clear differences in thermostability among these fish TMs, though the identity of amino acid sequences was more than 93.3%. Therefore, only a few amino acid substitutions could affect the overall stability of the TM molecule. Especially, several residues located on the molecular surface were considered to be responsible for such stability difference. In contrast, the molecular weights of these TMs as measured by mass spectrometry were higher than those calculated from amino acid composition, suggesting the presence of post-translational modification(s) which could also affect their thermal stability. |

| 摘要： | Tuna tropomyosin is a mixture of nearly equimolar amounts of two isoforms (designated a and b). cDNA encoding the a form was cloned from bluefin tuna Thunnus thynnus fast skeletal muscle. The full-length cDNA contained 1220 bp, comprising an open reading frame of 855 bp encoding 284 amino acid residues, flanked by 5¢-untranslational regions (156 bp) and 3¢-untranslational regions (209 bp). The deduced amino acid sequence showed considerably high homology in a range of 93.7–98.6% to those of other vertebrate a-type tropomyosins. In phylogenetic analysis, bluefin tuna tropomyosin showed the closest relationship with the white croaker counterpart. The predicted mass was 32 919 Da, and isoelectric point was 4.50, assuming acetylation of the Nterminus. By differential scanning calorimetry, bluefin tuna tropomyosin gave two major endothermic peaks at 29.3 and 41.5∞C, probably caused by the presence of two isoforms. Circular dichroism spectra supported such a unique denaturation profile. |

| 摘要： | cDNA encoding tropomyosin was cloned from walleye pollack Theragra chalcogramma fast skeletal muscle. The predicted mass was 32 588 Da and isoelectric point, 4.55, assuming acetylation of the N-terminus. The full-length cDNA contained 1168 bp, comprising a 5¢untranslational region (97 bp), a 3¢-untranslational region (219 bp) and an open reading frame of 855 bp encoding 284 amino acid residues. The deduced amino acid sequence showed considerably high homology in a range of 94–97% to those of other vertebrate a-type tropomyosins. In phylogenetic analysis, walleye pollack tropomyosin showed the closest relationship with the Atlantic salmon counterpart. By differential scanning calorimetry, pollack tropomyosin gave only one major endothermic peak at around 44∞C. Circular dichroism spectra supported this denaturation profile of pollack tropomyosin. |

| 摘要： | The effects of dietary lipid sources on the growth response of hybrid tilapia (Oreochromis niloticus×O. aureus) were investigated. Enzymic lipid peroxidation in the sarcoplasmic reticulum (SR) of these fish fed different dietary lipids was also studied. Experimental fish were given diets containing no additional lipids (control), lard, soybean oil, menhaden fish oil and methyl esters of n-3 highly unsaturated fatty acids (HUFA) for 10 weeks. There was no difference in survival rates among test groups. Compared to fish supplied with dietary lipids, fish consumed control diet with trace lipids (0.02%) were low in final body weights and muscle lipids. The specific growth rates and weight gains of fish fed soybean oil and fish oil were significantly higher than other groups (P0.05). Fatty acid compositions of muscle and SR reflected the fatty acid compositions of dietary lipids. The thiobarbituric acid reactive substances produced by iron catalyzed NADH-dependent lipid peroxidation were significantly different (P0.05) among SR isolated from fish fed different dietary lipids. Lipid peroxidation activity of HUFA group was the highest, followed by fish oil, soybean oil, lard and control group. |

| 摘要： | DNA was extracted from tissue samples from specimens of newly-collected Bathynomuskensleyi from Queensland and subsequently the COI and 16S rRNA sequences were successfully cloned. The holotype of B.kensleyi was also sampled for COI only. Comparison of the sequences showed that, for the COI sequences, B.jamesi and B.kensleyi have more than 59 different DNA positions amongst 596 known reading sequences. The Kimura two parameter (K2P) distance analysis confirmed that B.jamesi and B.kensleyi are two species. Indian records of Bathynomus are reviewed and three of the four identified species from India are shown to be misidentifications. Bathynomusdecemspinosus, B.doederlini and B.kensleyi are found to not occur in India and the only accepted record is that of Bathynomuskeablei Lowry & Dempsey, 2006. We conclude that, based on molecular analysis and morphological comparisons, the correct species identity of Indian species other than Bathynomuskeablei remains unknown. |

| 摘要： | Bathynomus jamesi Kou, Chen and Li, 2017 from Zhengbin fishing port in Keelung, Taiwan was identified by the shape of the distolateral corner of the uropodal endopod, shape of the clypeus, and the nucleotide sequences of the COI and 16S rRNA genes. Only two species of Bathynomus have previously been recorded from Taiwan, B. doederleini Ortmann, 1894, and B. decemspinosus Shih, 1972. Bathynomus kensleyi, previously known from the South China Sea as well as the South-east of Swain Reefs, Coral Sea, was primarily differentiated by the elongate and upturned pleotelson spines, but that characters is now shown to also occur in mature Bathynomus jamesi. Two specimens from the Gulf of Mexico (obtained from the Enoshima Aquarium in Japan) were compared to species of Bathynomus from the western North Atlantic. Sequence data showed that one of two samples was not B. giganteus Milne-Edwards, 1879, as had been assumed, and it did not match any other species of Bathynomus. That specimen was collected off the Yucatan Peninsula and is morphologically distinct from both B. giganteus (in the relative length of the antennal flagellum and length: width ratio of the pleotelson) and B. maxeyorum Shipley, Brooks, and Bruce in Shipley et al., 2016 (the number of pleotelson spines is 7 and distolateral corner is produced on uropodal exopod) it is here described B. yucatanensis sp. nov. Bathynomus is currently a very minor fisheries resource in Taiwan and Japan, but this find demonstrates the continuing importance of the fishing industry to marine biological exploration. |

| 摘要： | The fishery is an important industry, so how to operate sustainably is always an important issue. Therefore, Understanding the evolutionary relationships between different fish species is necessary to formulate different policies. Tropomyosin is now considered a molecular marker of fish phylogeny, but studies on higher-level phylogenetics are lacking. Tropomyosin is a structural protein located in muscle cells. It has the same conservative characteristics as RAG-1 (recombination activating gene 1), which is commonly used in higher-level phylogenetic studies in birds. Therefore, this study hopes to explore the feasibility of tropomyosin as a molecular marker for fish higher-level phylogenetic studies by comparing α tropomyosin with five mitochondrial DNA. In this study, the Molecular Evolutionary Genetics Analysis X (MEGA X) software was used to draw a phylogenetic tree for α-tropomyosin and 5 mitochondrial DNA genes in 32 fish. The results show that the fish skeletal muscle α tropomyosin amino acid phylogenetic tree compared to other molecular markers of mitochondrial DNA in a cohort is more similar to the phylogenetic tree established by Betancur-R in 2017. Therefore, it proves that fish skeletal muscle α tropomyosin amino acid has the potential to be a molecular marker for fish higher-level phylogenetic research. |

| 摘要： | 鰓虱科（Bopyridae）生物屬於等足目（Isopoda）上蝦亞目（Epicaridea），主要寄生於十足目（Decapoda）生物如蝦蟹之鰓腔，吸食宿主血淋巴液維生。被寄生之蝦蟹會造成生長不良、生殖障礙等問題造成族群量之減少。人類誤食可能導致過敏等食安風險，所以鰓虱之種類鑑定、生態及生活週期有必要被研究了解。不對稱鰓虱屬Discorsobopyrus是2004年自真蝦鰓虱亞科Bopyrinae分出之新屬，目前該屬只有一種生物記錄為思氏不對稱鰓虱（Discorsobopyrus stebbingi （Nierstrasz & Brender à Brandis, 1923）），該物種在文獻中記載宿主為東方異腕蝦（Heterocarpus sibogae de Man, 1917），本次發現為寄主新紀錄，其特徵有研究價值。2018年9月12日在屏東東港林氏異腕蝦（H. hayashii Crosnier, 1988）採樣中發現疑似上述寄生蟲。經解剖顯微鏡、電子顯微鏡觀察後發現：雌蟲與雄蟲間的體型差異極大、雌蟲體呈卵圓形 頭部較長，呈倒三角形並向後逐漸縮窄 顎足周圍具有小短刺，沒有觸鬚，兩面皆呈裂片狀，顎足上側具有些許小突起的構造以及稀疏的剛毛，第一對卵板呈不規則卵形或三角形，內面平滑。第一觸角（antenna-1）和第二觸角（antenna-2）各存在一節等，且其宿主同樣屬於長額蝦科（Pandalidae）。根據上述特徵鑑定為思氏不對稱鰓虱（D. stebbingi）。以18S rRNA序列作分子系統學分析結果得知，思氏不對稱鰓虱和寄生在長額蝦科（Pandalus borealis）之Hemiarthrus abdominalis親緣最為相近。本研究期望能提供不對稱鰓虱屬記錄，並作為生物多樣性及海洋資源管理之參考。 |

| 摘要： | Holophryxus fusiformis Shiino, 1937, a species of dajid isopod that attaches
to the carapace of sakura shrimp, Lucensosergia lucens (Hansen, 1922), is reported
from the sea of Taiwan for the first time. This species was first described as infesting
Prehensilosergia prehensilis (Bate, 1881) from Kanbara, Shizuoka Prefecture,
Japan. The current finding represents the second occurrence of H. fusiformis and identifies
a new host. Approximately 1% of the sakura shrimps in Yilan, Taiwan are infected
by H. fusiformis. Holophryxus fusiformis has been found offshore from both Yilan,
Taiwan and Nagasaki and in Suruga Bay, Japan; thus, the distribution of the parasite
possibly follows the Kuroshio Current. When large quantities of parasites occur in the
sea of Taiwan, the parasites are likely to flow into the Japanese waters along with the
Kuroshio Current, subsequently influencing the production of the Japanese sakura
shrimps. The establishment of a monitoring program for infection of the dajid in sakura
shrimps between Taiwan and Japan is recommended. This study provides additional
information on this species, including a new host, distribution, redescription, infection
rate, and morphological variation. |

| 摘要： | Tilapia is a very common aquaculture species in Taiwan and both the so-called freshwater tilapia (Oreochromis niloticus) and seawater tilapia (O. mossambica) are available. In order to characterize muscle tropomyosin from these tilapia and hybrid ones (O. mossambica × O. niloticus ), the biochemical properties of tropomyosin among these tilapia species were analysed. The nucleotide sequences of tropomyosin genes were determined by cDNA cloning, and the amino acid sequences were deduced. Fast skeletal muscle tropomyosins were isolated by the combination of isoelectric point precipitation and salting out with ammonium sulfate. The thermodynamic properties of the purified tropomyosins were examined by differential scanning calorimetry (DSC) and circular dichroism (CD) spectrometry. The results showed that those tropomyosins were identical to each other including the deduced amino acid sequence, thermodynamic patterns as measured by DSC and CD, except the partial differences in the nucleotide sequence, namely, at 99th (A/G), 183rd (T/C) and 846th (T/C) positions in the open reading frame. |

| 摘要： |
Fish are vertebrates and the largest number of biological species, they also have high degree of biodiversity. In order to survival in different environments, fish develop many patterns or mechanisms to adapt surrounding changes. For this reason, there are many fishes look similar but not the same species. To identify a correct species is an difficult but important issue for fish science. Today species identification and classification of commonly used molecular markers including mitochondrial cytochrome b and cytochrome c oxidase subunit I. But not all of them are applicable for above systems. This study wanted to use tropomyosin as a new molecular mark ers for fish identification, classification and development. Movement proteins are long-standing presence protein, one of movement proteins, tropomyosin can coordination of regulation and the promotion of muscle contraction with actin and myosin. This study use highly conserved features of tropomyosins as a molecul ar markers by DNA or protein sequences. The use of the logged database of fish muscle tropomyosin amino acid and DNA sequences to calculate and simulation five fish relationship including white croaker (Pennahia argentata ), northern bluefin hula (Thunnus thynnu s), tiger pufferfish (Tnktfugu rnbr ipes), zebrafish (Donio rerio), Atlantic salmon (Salmo salar). We will investigate whether tropomyosin can become a good molecular markers or not. By results, we found the primary and second structure of tropomyosin were different among the five fishes. The various of structure could help the fish with some different biological functions to adapt environment. The results of used tropomyosin as molecular marker to establish phylogenetic tree were more close to traditional theory than used other marker s. This means that tropomyosin can be used as molecular markers for fish evolution and phylogenetic analysis . The study wish to take views to explain the relationship between biological evolution by tropomyosin and a new molecular marker to species identification. |

| 摘要： |
From April to July, the Pacific bluefin tuna (Thunnus thynnus orientalis) will migrate to Taiwans east coast every year. The bluefin tuna is one of the important fishery species in Taiwan. Since bluefin tuna taste good, it often as sashimi and other Japanese cuisine advanced ingredients. In those years, the reduced amount of resources to make bluefin tuna renew high prices records in the international market. It is important for meat colors of bluefin tunas, red meat is fresh and quality assurance. But the Donggang fishermen legend meat that presents a pale, soft and a little sour of tuna meat known as ＂cooked-meat＂ (pronounced Taiwanese to Sik-Bah). Cooked-meat is an abnormal meat, often occurs in the case of tuna muscle, especially bluefin tuna (Thunnus thynnus), bigeye tuna (Thunnus obesus) and yellowfin tuna (Thunnus albacares). Donggang fishermen describe the main features of cooked-meat as follow; pale flesh, lack of flexibility and sour. Foreign reports ＂burnt meat＂ are very similar to cooked-meat because their features also have pale, lack of flexibility, slightly sour and others. Is the ＂cooked-meat＂ same as ＂burnt meat＂? Because Taiwan have no any references, it is difficult to determine. This paper aims to explore the biochemical property between ＂burnt meat＂ and ＂cooked-meat＂. In order to know the characteristics of cooked-meat, interviews for tuna related worker 30, and sampling cooked meat for laboratory analysis including pH, color quality (L*, a*, b*) and electrophoresis. The results of interview by Donggang fishermen show that the property of cooked-meat including pale (90%), soft (73%), sour (67%), rancid (53%). May cause cooked meat at a temperature factor was the highest (93%), followed by storage mode (53%), the period time of death (37%), sun or moon irradiation (30%), gender impact (30%), species strain (27%), death struggle (20%). The results of the data showed that the pH value of cooked-meat (5.56 ± 0.1, n14) was lower than normal meat (5.96 ± 0.2, n14). The color values of brightness (L*) (39.61 ± 3.36 vs 29.07 ± 2.19, n14), blue and yellow degree (b*) (12.41 ± 2.88 vs 7.77 ± 2.90, n14) in cooked-meat significantly higher than normal one. The SDS-PAGE electrophoresis analysis for cooked-meat from Donggang collected shown near 50 kDa protein band degradation. To be compared with papers reported from Yamashita and Ochiai, the degraded protein was creatine kinase. From the above results, the conclusion that ＂cooked-meat＂ was the same as ＂burnt meat.＂ In this study, we make sure that ＂cooked-meat＂ was ＂burnt meat.＂ We will design new study by burnt meat references. |

| 摘要： | The mudskipper is one of the important wetland species. It plays a key role in the conservation of wetlands and waterfowl. The special and changing environment has given rise to the evolution of many physiological mechanisms adapted to wetlands. With high sensitivity to environmental changes, mudskippers are considered as indicator organisms of wetland environmental changes. This survey is focused on the ecology and lifestyle of the mudskippers in Tainan wetland, including mudskipper species, population size, Body Mass Index change, environmental change, ecological behavior, courtship and reproduction, nest analysis, etc. The results show that there are at least two species; namely, Periophthalmus modestus and Boleophthalmus pectinirostris in the coastal wetlands of Tainan with the population size growing and declining dynamically along with the natural environment and human activity. Moreover, there are growth changes affected by the environment. Based on three observation points; namely, Keliao, Mangrove and Anping, mudskippers grow best in Mangrove while thrive poorly in Anping. Salinity is the main environmental factor while dissolved oxygen is the second. The nest is found to have a dendritic structure. The mudskippers environmental tolerance is not strong as expected. This may cause mudskippers to disappear due to their vulnerability to environmental changes such as embankments, fish farms, roads and other public buildings that bring cement and affect their habitat. Relevant authorities are expected to include mudskippers in the list of endangered species and begin conservation measures that give importance to mudskipper ecology and related wetland research that will help develop a sustainable society and country. |

| 摘要： | Mudskipper (Periophthalmini boleophthalmus) is widely distributed in coastal areas and wetland in Taiwan. The fish has a well adaptability for changes to the aquatic environment like salinity, dissolved oxygen and temperature. The purpose of this study is to investigate the biochemical characteristics and thermal stability of muscle tropomyosin (TM) from mudskipper. We extracted the crude TM from mudskipper skeletal muscle by high speed centrifugation, isoelectric point, and salting out TM with ammonium sulfate. Then we purified TM by column chromatography and detected its characteristics by electrophoresis gel analysis, circular dichroism (CD), and differential scanning calorimetry (DSC). The results show the muscle TM from mudskipper skeletal muscle has only one major form of TM. The DSC analysis showed Tm near 44 ℃. The CD spectra know the major structure of TM protein is α-helix. We wish this study can provide some data for biodiversity and evolution in mudskipper, and can be useful for protein structure study.
大彈塗魚(Periophthalmini boleophthalmus)是一種台灣西海岸濕地常見的濕地魚類。能適應半水半陸的潮間帶環境。這種魚類棲息於河口水域、沼澤及泥灘，在泥下建造垂直地道構成的洞內居住。由於大彈塗魚的生態特殊，濕地環境之溶氧、溫度、鹽度變化劇烈，大彈塗魚如何適應溼地環境乃至於如何運動彈跳，肌肉結構及組成是重要關鍵。 本次研究以肌肉纖維中保守性較高之肌肉纖維-原肌凝蛋白(TM)為研究對象，探討大彈塗魚肌肉纖維TM的熱安定性為主，並與其他魚種做分析比較。研究方法如下：利用超高速離心、等電點沉澱、硫銨分化及離子交換樹脂等方式找出精製大彈塗魚TM蛋白質的條件，經由一次電泳確認蛋白質純化後再用二次電泳分析有無isoform存在，經示差掃描熱量分析儀分析(DSC)及圓二光偏極光譜儀分析(CD)與其他魚種做比較。 研究與分析結果顯示，大彈塗魚肌肉纖維中TM以一種型態出現，沒有isoform，蛋白質結構以α-helix為主，熔點Tm為44℃。熱穩定性較黑鮪(Thunnus thynnus)及阿拉斯加鱈魚(Theragra chalcogramma)安定的現象。希望這些研究能夠更幫助了解濕地生物在濕地環境及生理適應之模式，了解生物多樣性及在演化上之意義。 |

| 摘要： | Background: THP-1 is a human monocytic leukemia cell line derived from a patient with acute
monocytic leukemia. The cell line differentiates into macrophage-like cells by stimulation with
phorbol myristate acetate (PMA). Although it has been used frequently as a model for macrophage
differentiation in research including the FANTOM4/Genome Network Project, there are few
reports on its genomic constitution. Therefore, we attempted to reveal the genomic aberrations
in these cells with the microarray-based comparative genomic hybridization (aCGH) technique.
Findings: We report large aberrations, including deletions 6p, 12p, 17p, and trisomy 8, and
revealed breakpoints in the MLL and MLLT3 genes. Moreover, we found novel genomic aberrations
such as a hemizygous narrow deletion partially containing the TP73 gene and homozygous
deletions, including the CDKN2A, CDKN2B and PTEN genes.
Conclusion: In this study, we identified 119 aberrant regions in autosomal chromosomes, and at
least 16 of these aberrations were less than 100 kb, most of which were undetectable in the
previous works. We also revealed a total of 4.6 Mb of homozygous deleted regions. Our results
will provide a base to precisely understand studies involving the THP-1 cell line, especially the huge
amount of data generated from the FANTOM4/Genome Network Project. |

| 摘要： | To establish a model system for future lipid peroxidative and anti-oxidative research, some characteristics of an iron-catalyzed enzymic lipid peroxidation system in tilapia sarcoplasmic reticulum were investigated. Results of the experiments showed that this system preferred NADH to NADPH as the reducing agent. The rate of lipid peroxidation for the NADH added sample was significantly higher than for the NADPH added sample. The optimal pH for the reaction was 6.8. When the reaction temperature was raised from 1℃ to 25℃, the lipid peroxidation rates also increased. Since tilapia is a major cultured fish species in Taiwan and the supply is stable, the enzymic lipid peroxidation system in tilapia sarcoplasmic reticulum will be an excellent model for lipid peroxidative studies.

| 摘要： | Bathynomus doederleini was discovered by Ortmann, 1894, in Sagami Bay, Japan. It was also the second
creature of Bathynomus discovered after A. Milne-Edwards, 1879, discovered B. giganteus. B. giganteus belongs to
supergiants (which mature in a size range between about 170 mm to 500 mm), B. doederleini belongs to giant (the
giants mature in a size range from about 80 to 140 mm). The distribution area of B. doederleini is considered to be
from Sagami Bay, Japan, to the South China Sea and the Philippines. However, when studying B. doederleini from
Taiwan, it was found that there are some genetic differences between B. doederleini from northern Taiwan and
southern Taiwan. These phenomena have not been recorded and discussed in the literature.
To confirm the morphological differences between the north and southern species of B. doederleini in Taiwan,
this study re-confirmed the morphology of B. doederleini from Taiwan north and south Taiwan. |

| 摘要： | 【背景・目的】駿河湾の桜えびの生産量が減少したことで、学者たちは桜えびの基礎研究に注目になった。台湾の桜えびの主な産地は屏東東港と宜蘭亀山島で、漁師の間では両産地桜エビの種類が違うと噂さが流れたが、両者の違いは報告されていません。以上の理由から、本研究では台湾の屏東東港と宜蘭の桜えびの外観を比較し、形態的差異を調べた。
【材料・方法】2022年12月東港産と亀山島産桜えび各30匹を選び、75%アルコールで保存し、顕微鏡で桜えびの微細構造を観察。写真を撮ったり、記録しながら、両産地の桜えび外観を比べた。
【結果・考察】研究結果が示す；東港産と亀山島産の桜えび外観形態について、前頭角（Rostrum）の形と光器官（Photophores）の分布、第三顎脚（3rd maxilliped）、口器の色（Mandible)および交尾器（Petasma）の形などが異なり。東港産桜えびには、亀山島産より短い三角形の前頭角と不規則な額角があり。そして、内尾肢(Endopod) 2 つの発光体を持つ。亀山島産桜えび尾肢の先端は透明で、発光体を持たず。東港産桜エビの第三顎脚の色は、ほぼオレンジと赤オレンジ色で、2 つの発光体があり。その変わり、亀山島産桜えびの第三顎脚はほぼ黄色で、発光体の数は均等に分布している。その他、少数の東港産桜えびは、亀山島産桜エビには見られない現象があり。例えば、上腹部の腹膜(Pleuron)に 4 つの発光体があり、または発光体が欠失例もあり。鰓棘（Branchio-cardiac carina）上の発光体の数は比較的少ない。口器については、東港産桜えび口器の上部は通常的の赤色と橙赤色、オレンジの比率ははやや低い。亀山島産桜えびの口器の上部は通常オレンジ色、赤の割合が少ない。

| 摘要： | [背景] オオグソクムシ（Bathynomus doederleini）は1894年Arnold Edward Ortmann氏が駿河湾で発表した深海等足目生物であり、その特徴な形は戦国時代武士の具足と似てるから名前を得た。台湾島周辺海域でもオオグソクムシが生存しているが、種類はいつもオオグソクムシ（B. doederleini）と考えられた。駿河湾産のオオグソクムシと同じ種類がどうかを確かめるため、形態学と遺伝子学分析を行った。
[材料・方法] 台湾本島の大渓、東港、台東、及び外島東沙島付近海域の深海でオオグソクムシを採集した、サンプルは75%アルコールで保存。そして、日本駿河湾産オオグソクムシと形態を比較。その後、足筋肉からDNAを抽出、COIのDNA遺伝子配列をしらべた。
[結果] 台湾産オオグソクムシの外観は、ほぼ駿河湾産オオグソクムシと同じ形を持つ、形態学には同じ種類とみられる。しかしCOI のDNA遺伝子を分析するところ、台湾本島（大渓、東港、台東）と東沙島産オオグソクムシは同じ種類と判明、しかし日本駿河湾産オオグソクムシとは異なるDNA配列を持つことを示した。その形態学はほぼ同じ、しかしDNA遺伝子配列が異なる現象は、現在多いの生物で発現、隠蔽種(cryptic species)と呼ぶ現象であり。台湾産オオグソクムシの種類はB. doederleiniで良いかどうかを検討することが必要と考えられる。

| 摘要： | 【背景・目的】
台湾でのエビの産量は年々減っていることが明らかになっている。その原因として、寄生虫が関係しているのではないかという可能性が挙げられている。しかし台湾でのエビに寄生する寄生虫に関する論文等は少なく、また、寄生虫の形態の差はあまり大きく無く、形態類での誤解が生まれやすい。
寄生されたエビは移動速度が遅い、生殖腺萎縮、不妊、精子の量の減少などの症状があり、エビの繁殖と族群数量に影響している。
この研究は、解剖顕微鏡とデジタル顕微鏡を使用し、ヒカリチヒロエビ（Aristeus virilis ）の形態を観察し、またヒカリチヒロエビに寄生している寄生虫を観察した。
【材料・方法】
台湾の屏東県東港を中心に、チヒロエビを採集し、ヤドリムシ類の寄生を確認した。得られたヤドリムシ類は規制と共に記録し、冷蔵庫で98％アルコールで保存した。立体顕微鏡（SMZ1500，尼康，日本東京）とCCD系統を付けたソフトウェア計算機（NIS element D，尼康，東京，日本）を使用し、ヒカリチヒロエビ（Aristeus virilis ）の形態と寄生虫の肉眼での観察、正面、背面構造の差異、それを撮影し、書き写し記録した。
【結果・考察】
ヒカリチヒロエビは深海性エビで、水深 300m の大陸斜面に分布し、生態は底質浮遊性である。第3・第4・第5脚に無数の発光器がある。額角は短く真っ直ぐで、前端は眼球をわずかに超えて、第 1 触角柄の第 2 節の基部に達している。額の前部はわずかに下向きに傾斜している。前頭角の上縁には 3 つの歯があり、甲羅には触角の後棘がなく、甲羅には眼の後隆起がなく、第 1 脚と第 2 脚の遠位端に小さな棘がある。
寄生虫は、Orbione aristei (Species)（ Shiino 1949）であることが判明した。台湾では初めての記録となった。日本では、伊豆と戸田で発見されている。体は非対称の卵形で、背側がアーチ状になり、背側が平らになり、腹側正中線に沿って隆起した構造になっている。また目が無いのも特徴の一つである。 オスとメスでは約六倍の差があり、メスのほうが大きい。
Entoniscidaeの早期生活史と似ており、この二つの科は、「epicaridean 幼生」として生まれ、カイアシ類に寄生する（Copepods）その後、変態をし「microniscus幼虫」となる、時間がたつと、最後の寄生を十腳類の甲殼類でする。

| 摘要： | Tropomyosin is a structural protein located in muscle cells. It has the same conservative characteristics as recombination activating gene 1 (RAG-1). RAG-1 is commonly used in higher-level phylogenetic studies of birds. Therefore, this study compared five mitochondrial DNAs (12S rRNA, 16S rRNA, cytochrome b, cytochrome c oxidase subunit I, and NADH-ubiquinone oxidoreductase chain 5) commonly used in fish phylogeny with nucleotides and amino acids of α tropomyosin. We are exploring the feasibility of α tropomyosin as a molecular marker for higher-level phylogenetic studies of fish. In this study, 32 fish five mitochondrial DNA genesand α tropomyosin nucleotide and amino acid sequences were used to draw a phylogenetic tree using the Maximum Likelihood method in the Molecular Evolutionary Genetics Analysis 11 (MEGA 11) software. The results show that the phylogenetic tree drawn with α tropomyosin amino acids as molecular markers has the closest results in fish higher-level phylogenetics with the fish phylogenetic tree established by Betancur-R in 2017. It can be seen that α tropomyosin amino acid is feasible as a molecular marker for studying higher-level phylogenetics of fish. |

On December 14, 2020, one individual of female tuna has been caught in the western waters of Xiaoliuqiu, Taiwan, with the size of bluefin tuna, anal fins of bigeye tuna and pectoral fins of yellowfin tuna. Besides, the fish had mature ovaries and developing eggs. The fishermen thought it was a hybrid with very low frequency. In order to find out whether this peculiar tuna is a hybrid or not, we tried to analyze the parent species of this fish with molecular biological methods.

Using the principle of maternal inheritance, we tried to analyze the cyt b sequence of mitochondrial DNA, while microsatellite repeat sequence analysis was applied to paternal inheritance. The genomic DNA was isolated from the ordinary muscle, and primers were designed bases on the sequence of conserved regions. The PCR amplified products were sequenced.
【Results and discussion】
According to the cyt b sequence from the maternal genetic analysis, the mother of this peculiar tuna was demonstrated to be Pacific bluefin tuna (Thunnus orientalis). The patrilineal examination is still under analysis. Further research could contribute to breeding of tunas with useful genetic characters.

| 摘要： | Bathynomus species are deep-sea crustaceans distributed in the deep ocean floor of the Pacific, Atlantic and Indian Oceans. According to the references, there are at least three species of Bathynomus in the South China Sea, including B. doederleini, B. kensleyi and B. jamesi. The differences between the species of genus Bathynomus are very small and not easily distinguished based on the morphology (Fig. 1, Table 1). The upwardly curved pleotelsonic spines are often considered to be the characteristics of B. kensleyi by the Taiwanese media. To identify the species, we used COI gene of the mitochondrial DNA as the marker.
The three samples were collected from Zhengbin Fishing Port in Keelung, Taiwan on 17 July, 2019. According to the information from fishermen, coupled with the GPS record of the fishing vessel involved, these samples were captured in waters of the Pratas Islands about 430 km south-west of Kaohsiung, Taiwan. The genomic DNA was isolated from the pereopods muscle. The primers were designed based on the sequences of the conserved regions of COI. The PCR-amplified products were sequenced using a DNA sequencer.
The sequences of COI from the three individuals collected from Pratas Island waters were almost identical to that of B. jamesi collected off Hainan Island, China, in 2017, instead of B. kensleyi. Because both B. kensleyi and B. jamesi have the upwardly curved pleotelsonic spines, molecular biological identification is thought to be essential for their identification.

| 摘要： | [Background] The genus Holophryxus of dajid isopod was established by Richardson in 1905. The H. fusiformis was first discovered in Suruga Bay by Shiino in 1937, but the second record was the one after 80 years in Guishan Island, Yilan, Taiwan. This species is usually yellow and spindle-shaped, parasiting on the carapace of the sakura shrimp Lucensosergia lucens. In order to understand the phylogenetic relationship between H. fusiformis and the other marine isopoda, 18S rRNA gene was cloned and sequenced as the target.
[Material & methods] The specimens of sakura shrimp and attached H. fusiformis were collected in Gueishan Island and stored in 70% ethanol at -20 °C. The 18S rRNA gene was with a QIAamp DNA Mini Kit (QIAGEN) and used as a PCR template. The nucleotide sequence obtained was subjected to phylogenetic analysis using Molecular Evolutionary Genetics Analysis 7.0.
[Results & discussion] A total of 1200 bases was obtained from the 18S rRNA gene of H. fusiformis. When the sequence was compared with those from 15 species of bopyroid isopods registered on the database of National Center for Biotechnology Information (NCBI), it was found that Zonophryxus quinquedens was the closest to H. fusiformis among the species examined.

| 摘要： | [Background] Acipenseriformes, one group of ancient fish species, has been diverged at the earlier stage of fish evolution. Acipenseriformes is divided into two families, Acipenseridae and Polyodontidae. Between them, there are a few apparent differences in their biological characteristics. In this study, in order to investigate the phylogenetic relationship between them, the amino acid sequences and higher structures of tropomyosins from Amur sturgeon Acipenser schrenckii (Acipenseridae) and American paddlefish Polyodon spathula (Polyodontidae) were examined.
[Material & Methods] Live specimens of the two species were provided by Chienhu Cheanchi Ecological Fish Farm, Taipei, Taiwan. RNA was extracted from the fast skeletal muscles. The tropomyosin cDNAs were synthesized with reverse transcriptases. The nucleotide sequences obtained were then deduced to the amino acid sequences by Translate Tool. The comparison in hydrophilicity and hydrophobicity was implemented by ProtScale, whereas the 3D structures were predicted by SWISS-MODEL. Phylogenetic tree based on the amino acid sequence was also drawn by MEGA7.
[Results & discussion] Tropomyosins from these two species were 98% identical in the amino acid sequence, and thus showed considerable similarity in hydrophilic and hydrophobic scores, and 3D structure. In the phylogenetic tree, the two species were clearly isolated from the other Osteichthyes species. The results suggest that Acipenseriformes have diverged from the other fish species at the very early stage of evolution.

| 摘要： | [Background] Since the first discovery of O. aristei Shiino, 1949, (Crustacea, Isopoda, Bopyridae, Orbioninae) in Japan in 1949, there has been no record of their occurrence. At present, the research on bopyridae in Taiwan is fragmentary. In this study, the current status of bopyrid O. aristei parasitism on A. virilis (Crustacea, Decapoda, Penaeoidea) in Taiwan was investigated by morphological and molecular biological approaches.
[Material & methods] A total of 116 individuals of A. virilis purchased at a fish market in Donggang, Taiwan and the parasite sampled therefrom were stored in 70% ethanol and stored at -20 OC until used. The morphology was observed under a dissecting microscope equipped with a CCD system. The 18S rRNA gene was cloned and sequenced for the phylogenetic analysis.
[Results & discussion] The parasite was identified as O. aristei based on the following observations. Firstly, the host recorded in this study and the previous studies were A. virilis. Secondly, the female antennule and antenna possessed two and three articles, respectively, and the oostegites completely enclosed the brood pouch, etc. Thirdly, the male antennule and antenna possessed three and four articles, respectively, and the shape of the pleotelson was inverted triangle with a blunt tip. Fourthly, the nucleotide sequence of 18S rRNA gene from O. aristei was clearly different from those of the other bopyrid isopods.

| 摘要： | [Background] The bopyridae P. tertium Nierstrasz & Brender à Brandis, 1932, has been known to be parasitic on the shrimp Metapenaeopsis provocatoria longirostris Crosnier, 1987. We found this parasite on a new host shrimp A. virilis, Spence Bate, 1881. The parasitized shrimps suffer from many problems such as stunting and reproductive disorders, causing economic damages to fisheries community. In this study, the bopyrid P. tertium was characterized based on morphological and molecular biological approaches.
[Material & methods] Total of 22 individuals of the shrimp A. virilis, with swollen gills were collected on Oct. 9th, 2019 at a fish market in Donggang, Pingtung, Taiwan. The parasites freshly removed manually were soaked in 70% ethanol and kept at -20°C until used. The morphology of the parasites was observed under a dissecting microscope and a scanning electron microscope. The occurrence of parasitism by this bopyrid and its phylogenetic relashionship were examined based on the 18S rRNA gene sequence.
[Results & discussion] The shrimps were not similar to the one reported by Boyko (2004). This study is the first report for P. tertium parasitic on the new host A. virilis. The head of the parasite in female individuals was slightly longer and wider than those in males tapering posteriorly, strongly produced with frontal lamina equal to approximately one third of the head in length, and the antenna and antennule consisted of four articles. The barbula of the parasite in the females was one-paired, and the margin of the head was accompanied with numerous irregular lobes. On the other hand, the parasites in the males had six and three articles in the antennae and antennule, |

| 摘要： | [背景]「龍」は中国の重要なシンボルであり、水と密接な関係がある。東漢王朝の許慎《說文》には龍の特徴として「鱗蟲之長。能幽，能明，能細，能巨，能短，能長．．．」とあり、「龍」が想像上の動物ではないことを示唆する。本研究は、古代において「龍」に相当する動物、その原形となる生物種が魚類である可能性を含めて解明することを目的とした。
[方法]甲骨文にある「龍」の形体と、古代に書かれた文献をもとに「龍」の生物学的特性を分析した。さらに、古代の「龍」と現存生物の特徴を系統分類学的に比較した。
[結果]文献にある「龍」は、近縁生物として、ヘビ、ワニ、トカゲおよびチョウザメの４つに集約された。なかでも、ヘビ型とワニ型がより近縁と考えられた。甲骨文にみる「龍」の特徴は、体が細長くて足がなく、巨大な頭と2本の巨大な牙があり、頭を上げることができることにある。 したがって、足があるワニやトカゲ、巨大な牙がないニシキヘビやチョウザメは該当しないことになる。そのため「龍」の原型は巨大な毒ヘビと考えるのが妥当であり、中国にみられる巨大な毒ヘビの中で大きな頭をもつものとして、コブラが最有力である。すなわち、商王朝以前に「龍」と呼ばれ、現在では中国南部および台湾に分布するタイワンコブラNaja atraである可能性が高いと考えられた。
【背景】龍是中國的重要象徵，與水有著密切的關係。東漢許慎《說文》中，龍的特徵是「鱗蟲之長。能幽，能明，能細，能巨，能短，能長．．．」 “龍”並非是虛構的角色，這表明它是動物。這項研究的目的是闡明古代龍的對應動物，包括其原始形態是魚的可能性。
[方法]根據甲骨文和古代文獻中發現的“龍”的形狀，分析“龍”的生物學特徵。此外，還對古代「龍」和現存生物的特徵進行了系統發育比較。
[結果]文獻中的「龍」被歸類為四種相關生物：蛇、鱷魚、蜥蜴和鱘魚。其中，蛇形和鱷魚型態被認為關係較為密切。甲骨文中所見的「龍」的特徵是，身體細長，沒有腿，頭巨大，有兩顆巨大的獠牙，並且能夠抬起頭。因此，有腿的鱷魚和蜥蜴，以及沒有大毒牙的蟒蛇和鱘魚，不屬於這一類。因此，有理由認為龍的原型是巨型毒蛇，而在中國發現的巨型毒蛇中，眼鏡蛇最有可能擁有大頭。換句話說，人們認為它極有可能是台灣眼鏡蛇（Naja atra），它在商代之前被稱為“龍”，現在分佈在中國南部和台灣。

| 摘要： | [Background] On November 8th, 2018, an individual of kuruma prawn Marsupenaeus japonicus (Spence Bate, 1888) with swelling gills was found at a fish market in Penghu, Taiwan. Attempts were made to identify causal parasite species in this study.
[Methods] The morphology of the parasite freshly removed from the host prawn was observed under a stereomicroscope and an optical microscope.
[Results & Discussion] It was found that the parasite was more similar to Parapenaeon japonica (Thielemann, 1910) or Epipenaeon ingens ingens (Nobilli, 1906, Crustacea, Isopoda, Bopyridae), but not to Pleurocrypta reported by Ishii in 1916, nor Orbioninae sp. reported by Saito in 2002, It was more likely to be E. ingens ingens based on the characteristics of the five pleomeres, all lateral plates being well developed, and pereon segments being distinct. In this study, E. ingens ingens, that anchored the gill of kuruma prawns, was found from the Sea of Penghu for the first time and approximately 1% of the kuruma prawn in Penghu were parasitized by this species. According to references, prawns parasitized by bopyridae suffer from physiological problems such as stunting and reproductive disorders. Due to the damages to their reproductive functions, these parasites could reduce the population of prawns and affect their resources. The species is to be confirmed by a molecular biology method, and further investigation of its physiological and ecological profiles would favor fishery resource management.

| 摘要： | During the Northern Song Dynasty, the northern nomad called Khitan was distributed in the wide range which represents the northeast of present China and the broad area in Mongolia. In 907 A.D, the Liao Dynasty had been founded by Abaoji. According to the descriptions in Miscellany of Yenbei by Wu Gui, "The northern savages hooked cattlefish in Daru River.", but little information is available about the species. Regarding the "cattle-fish", there had been some valuable statements to be compared and verified in the documents over the past dynasties. According to the Record of Yenbei by Wang Yi, "cattle-fish has a long mouth, hard scales, and brittle bones of head weight about a hundred catty. It is so-called the sturgeon in the south," and "Cattle-fish is a bigger sturgeon." As Fang Yizhi in Tong-Ya wrote, "Cattle-fish, is a sturgeon from the north". It was also considered that cattle-fish was exactly a sturgeon. Compendium of Materia Medica by Li Shizhen quoted the saying of Chen Zhanchi, “Cattle-fish originates in East China Sea, and the shape of its head looks like a cattle," in which not only sturgeon but also cattle-fish have been mentioned. Therefore, Li thought that both of them were not the same creature. In Fantastic Tales by Ji Xiaolan, Ji narrated, "Cattle-fish, which is so-called kaluga, had been valued in Jin Dynasty, as at the present." Apparently there are various explanations for "cattle-fish". This essay will focus on the History of The Liao Dynasty to boldly expound the distinct creatures or the different species with the same name that "cattle-fish" had referred to in a variety of dynasties and areas by not only researching the related texts with the records of "cattle-fish" since the Liao and the Song Dynasty, but contrasting features of creatures described in the ancient texts. The creatures which had been called as "cattle-fish" might include Psephurus gladius, Huso dauricus, Dugong dugon, Orcinus orca, Silurus glanis and so on; thus, there is a higher possibility that P gladius might be the "eattle-fish" mentioned in History of The Liao Dynasty. |

| 摘要： | [Background] The bopyridae Discorsobopyrus stebbingi (Nierstrasz & Brender a Brandis, 1923) is known to parasite on the shrimps Heterocarpus siboage (de Man, 1917) and H. hayashii Crosnier (1988). The shrimps parasitized by this bopyridae suffer from many problems such as stunting and reproductive disorders, causing economic damages to fisheries community. In this study, attempts were made to characterize the parasitism by this species.
[Material & methods] The parasite shrimps were collected in a fish market at Pingtung, Donggang, Taiwan. Total of 36 individuals of Heterocarpus shrimps with swollen gills were collected in Sept. 2018, and the parasites freshly removed were soaked in 75% ethanol and kept at -20°C. The morphology was observed under a dissecting microscope and a scanning electron microscope. Molecular biological analysis on the occurrence of parasitism was also performed based on the 18S rRNA sequence.
[Results & discussion] The shrimps were identified to be H. hayashii, similar to the one reported by Boyko (2004). It has been observed that the sizes of male and female were so different, namely, the female head was inverted triangle, and the antenna and antennae were only one and hairless. The male had a two-section antenna and one section of tentacles, together with a mid-ventral tubercle. Based on the molecular biology analysis of 18S rRNA, approximately 0.1% of the shrimps examined was found to be parasitized by D. stebbingi.

| 摘要： | 日本周辺に生息するメジナ科魚類の産卵生態は、メジナGirella punciataについては報告されているがクロメジナGirella leoninaについてはほとんど報告されていない.本研究では,メジナとクロメジナの産卵生態の種間差を明らかにするため,伊豆半島沿岸と種子島沿岸から両種を収集し、生殖腺指数 (GSI)と生殖腺の組織形態に基づき両種の成熟過程を調べた. 種子島海域のメジナは3月に著しく高いGSI値を示しており、伊豆半島海域のピーク時期(4月)より早かった。GSI値の高かったメジナは両海域とも組織学的に成熟した卵巣と精巣を春季に有していたことから,メジナはこれらの海域で春季に産卵することが示唆された.
クロメジナのGSIは対照的に低い値を示したが、その最大値は雌雄とも伊豆半島海域より種子島海域で高かった.また,クロメジナの卵形成は伊豆半島海域より種子島海域で進んでいた。この結果から,種子島はクロメジナの産卵海域に比較的近いことが示唆された.
【目的】日本沿岸に分布するメジナ属魚類3種のうち，繁殖生態が詳しく報告されているのはメジナのみであり，他2種の繁殖生態は良く分かっていない．本研究では，漁獲量が多いメジナとクロメジナについて繁殖戦略の種間差を明らかにするため，成熟度分析と着底稚魚の出現状況調査を実施した．
【材料及び方法】台湾近海及び南西諸島沿岸で漁獲されたメジナ属成魚を収集し，生殖腺を摘出して成熟度分析を実施した．また，関東—伊豆地方および九州南部地方の沿岸域でメジナ属の稚魚を採集し，DNA分析に基づいて両種の出現種組成を調べた．
【結果】12–3月に台湾近海で漁獲されたクロメジナから成熟期の卵細胞が検出されたことから，本種は台湾近海の熱帯・亜熱帯海域で冬から早春にかけて産卵しているものと推察された．本種の着底稚魚は，黒潮の流路から離れた相模湾では冬季に全く採集されなかったのに対し，黒潮沿いの相模灘では1–3月に豊富に採集された．トカラ海峡北側の種子島の海岸でも，本種の着底稚魚は3月に採集された．したがって，日本沿岸に来遊する仔稚魚は黒潮流路に近い岩礁底の暖水環境の中で成育すると考えられる．一方，メジナの着底稚魚は相模灘と相模湾の両海域で晩春から初夏にかけて豊富に採集された．メジナの成熟個体は，本州から九州にかけての海域で3–5月に漁獲されることが報告されている．以上の結果から，メジナは「春季昇温依存型」，クロメジナは「暖水海域依存型」の繁殖戦略をとっているものと推察された．

| 摘要： | [Introduction] Tropomyosin (TM) is an actin-binding protein that is highly conserved throughout evolution. Regarding fish skeletal muscle TMs, the primary structure has been determined for many species, and the occurrence of isoforms has been reported. However, insufficient information is available on the structure of fish muscle TMs so far. In this study, attempts were made to reveal the diversity of fish TMs by structural analyses.
[Materials and methods] Live specimens of fishes including Taiwan torrent carp Acrossocheilus paradoxus, round-snout nose Distoechodon tumirostris, Taiwan shoveljaw carp Onychostoma barbatulum and lake candidius dace Candidia barbata) were purchased at a local market in Tainan City, Taiwan. Total RNAs were isolated from fast skeletal muscles, and the first strand cDNAs were synthesized. PCR was subsequently carried out and amplification products were subjected to nucleotide sequencing. Sequence homology search, secondary structure prediction and phylogenetic analysis were performed using the ExPASy bioinformatics tools. The 3-D structure was predicted by Swiss Model Automatic Modelling Mode and DeepView softwares.
[Results and discussion] All PCR products having approximately 900 bp contained the CDS nucleotide sequences (1-852) encoding 284 amino acids. These fish TMs were considered to be α-type by comparing with the sequences of TMs so far reported. Their 3-D structures generally resembled each other, but small variations were recognized, probably as a result of environmental adaptation and evolution.

| 摘要： | 「鮪」、「鱏」、「鱣」は古代中国漢『說文解字』の時代から存在する古い文字であるが、時代の流れとともに意味は変わっていった。今は「鮪」が良く使われるが、「鱏」や「鱣」はほとんど使われていない。現在、「鮪」は「まぐろ」と読むが、漢代にはその意味はなかった。本研究は中国古代の文献を元に、現代の分類学に基づいて、古代文学に描写された魚種の同定を試みたものである。
漢の時代以前は「鮪」、「鱏」、「鱣」は現在のどの魚種に相当するのかについて、多くの古代中国の文献における、これらの文字の記載例を分析しながら、生物学的特徴を分類学で調べた。その結果、「鮪」と「鱏」は同じ魚であるが、中国北部では「鮪」と呼び、南部では「鱏」はヘラチョウザメ (学名：Psephurus gladius) と呼ばれる絶滅危惧種であることが判明した。およそ二百年前にはまだ中国各地の大きな河川に生息していた巨大魚であった。その他、「鱣」も中国各地に生存した巨大魚で、現在はカラチョウザメ (Acipenser sinensis) とされている。しかし中国には蒙古、女真などの異民族文化が入り、「鱣」の意味もダウリアチョウ (Huso dauricus) やアムールチョウザメ (A. schrenckii) にまで拡大し、その後、中原のカラチョウザメとダウリアチョウを区別するため、新たに「鰉」の字が誕生した。つまり清時代の後、「鰉」はダウリアチョウザメを意味するようになった。一方、「鮪」は大きい魚という意味であり、シビに繋がると思われる。「鮪」が梶木も意味するのは、「鮪」が中国南部の「鱏」であり，その訓読みがカジキであるためである。日本の遣唐使が中国南部で川に「鱏」を見た時、その特徴的な長い吻から、日本に帰ってカジキを見て「鱏」と勘違いしたのではないかと考えられる。

| 摘要： | , .[Introduction] Fish show spcies biodiversity in the strategies to adapt to respective environments. Many attempts have been made to clarify the genetic relationships based on some molecular markers such as mitochondrial cytochrome b (cytb) and cytochrome c oxidase subunit I (COI) genes. Not all of them are, however, successful in these attempts. Muscle tropomyosin (TM) is one of the regulatory proteins of muscle contraction, and its structure is characterized by a typical coiled-coil formed by conservative amino acid sequences. In this study, the availability of TM as a new molecular marker for phylogenetic analysis of fish was evaluated, by taking the advantage of highly conserved features of TM sequences.
[Methods] The DNA and deduced amino acid sequences of TM, cytb and COI from white croaker (Pennahia argentata), bluefin tuna (Thunnus orientalis), pufferfish (Takifugu rubripes), zebrafish (Danio rerio), Atlantic salmon (Salmo salar) were used. The phylogenetic analyses were performed by using different analytical methods such as maximum likelihood, neighbor joining and UPGMA.
[Results and discussion] The phylogenetic trees drawn based on TM sequences were similar to those constructed by using traditional markers. The primary, secondary, and the modelled 3-D structures of TMs were similar to each other, but distinguishable among the five species. Such differences in the structure imply the involvement of TM for adaptation of fish concerned to each habitat. It is suggested that TM can be an excellent molecular marker for the phylogenesis of fish and would give valuable crews to their evolution.

| 摘要： | .[Introduction] Fish show a large biodiversity in the strategies to adapt to respective inhabiting environments. In order to know the genetic relationship among fish species, many attempts have been made based on various molecular markers such as mitochondrial cytochrome b (cytb) and cytochrome c oxidase subunit I (COI). Not all of them are, however, successful for this elucidation. In the previous study, we found the availability of muscle tropomyosin (TM) as a good molecular marker. In this study, myoglobin (Mb) was evaluated as a possible alternative molecular marker for the elucidation of phylogenetic relationship of fish.
[Methods] Publicly available data of the DNA and deduced amino acid sequences of Mb, cytb and COI were obtained for longtooth grouper (Epinephelus bruneus), medaka (Oryzias latipes), whale shark (Rhincodon typus), bluefin tuna (Thunnus thynnus), green spotted puffer (Tetraodon nigroviridis), torafugu (Takifugu rubripes), zebrafish (Danio rerio), Atlantic salmon (Salmo salar) and tilapia (Oreochromis mossambicus). The phylogenetic analyses were performed based on the different methods namely, maximum likelihood, neighbor joining and UPGMA.
[Results and discussion] The phylogenetic trees depicted based on Mb sequences were similar to those based on the traditional classification markers. The primary, secondary, and the modelled 3-D structures of Mbs were similar among Mbs from different fish species, but were clearly distinguishable among the nine species. Such differences in the structures would be responsible for adaptation of Mb molecules to the physiological conditions of each species. These results suggest that Mb can be a molecular marker for the phylogenesis of fish, but is slightly inferior to TM.

| 摘要： | [Background] Milkfish is one of the popular aquaculture species in Southeast Asia. In winter, especially after the cold current passes through Taiwan, many milkfish cannot survive because of low water temperatures. It has become a serious problem for aquaculture industry and gives economic damage for fishermen. The reason, however, has still remained unclear. While some other tropical species such as mudskipper, grouper and tilapia are also farmed, they hardly die unlike milkfish. In this study, the thermodynamic properties of tropomyosin from these species were compared to address the question.
[Materials and methods] The nucleotide sequences of the tropomyosin genes were determined by cDNA cloning, and their amino acid sequences were deduced. Fast skeletal muscle tropomyosins were isolated by a combination of isoelectric point precipitation and salting out with ammonium sulfate. The thermodynamic properties of the purified tropomyosins were examined by differential scanning calorimetry (DSC) and circular dichroism (CD) spectrometry.
[Results and discussion] The results showed that the deduced amino acid sequences of tropomyosins from the above species were similar to each other, with the identity being 96-98%. Thermodynamic analysis showed that the milkfish tropomyosin has lower refolding ability after heating up to 80℃, compared to those of the other species. It is still unclear whether such low stability of milkfish tropomyosin is directly related to the lower tolerance of this species against cold water, but could support the technical approach to this question.

| 摘要： | Tilapias are common aquaculture species in Taiwan. The most common species are Oreochromis niloticus, O. mossambica and a hybrid O. mossambica (♂) × O. niloticus (♀)). Tropomyosin is a fibrous protein involved in muscle
contraction regulation, and is also responsible for the quality of muscle foods. This protein is also of great interest from the viewpoint of molecular evolution and the structure-function relationship. In order to reveal the structural
profiles of tropomyosin from different strained tilapias, we investigated the characteristics of skeletal muscle tropomyosin composition for the above tilapias based on gene cloning.Total RNA isolated from dorsal skeletal muscle
from tilapias was utilized as the templates for PCR amplification and sequencing of cDNA encoding muscle tropomyosin using the gene-specific primers. The cDNA was cloned into the bacterial expression vector pGEM-T Easy
and the protein was expressed in E. coli strain of JM109 cells. The sequences were edited and analyzed by BioEdit program. The results obtained showed that the open reading frames for all the tropomyosin genes contained 852 bp
encoding 284 amino acid residues. Tropomyosin genes from the three tilapias had slightly different nucleotide sequences coding the same amino acid sequence. The deduced amino acid sequence showed a considerably high
homology in a range of 94-99% to those of the other fish α-type tropomyosins reported so far. By the phylogenetic analysis, tropomyosin from the hybrid tilapia showed the closest relationship with that from nilotica species O.

| 摘要： | [Objective] The sea beds of west Taiwan mostly belong to the continental shelf. The Dong Gang Coast is the only one place deeper than 200 meters, with unique ecosystem and biodiversity. In the present study, attempts were made to measure the concentrations of heavy metals and trace elements in the muscles of fish species inhabiting the waters in order to examine the effect of water pollution in the waters concerned in inhabiting fish species.
[Methods] Three teleost fishes, namely, horned lanternfish Diaphus splendidus, Japanese barracudina Lestrolepis japonica, and kamohara grenadier Coelorinchus kamoharai, and two elasmobranch species, blue shark Prionace glauca and silky shark Carcharhinus falciformis, were collected in a local fish market in Dong Gang. The five species of fish were very common species and fresh specimens are available in this area. The specimens were stored at -20℃ until used. The dorsal ordinary muscles were excised and minced with a mincer and were dried in an oven during 8 h. Two hundred milligrams of dried powders was applied to a Microwave Digestion System. The inductively coupled plasma-reactive ion etching (ICP-RIE) was used to determine the contents of Mn, Fe, Ni, Cu, Zn, Cd, Pb, Se, Cr, Ge, Sn, Hg, and As in the samples.
[Results and discussion] The most of the elements were found in fish muscles except Sn. Although Pb was not detected in the teleost fish species, the two shark species gave the value higher than 2,000 ppm. Fe, Mn, Ge, As, Zn, and Cd in the teleost fish were higher than in the sharks. Ni content in shark muscles was higher than in the teleost fishes. On the other hand, the contents of Cr, Hg, and Cu were similar to each other among the above teleosts and sharks. The results demonstrated that the sharks as high level predators had more concentrated levels of heavy metals than those of lower levels. The bioaccumulation of these elements seems to have taken place along Dong Gang Coast. It is suggested that some elements such as Hg and Cr have originated from industrial pollution.

| 摘要： |
熟肉(burnt meat) 是異常肉的一種,常可在黑鮪肌肉發生,台灣東海岸在四月至七月常可補到太平洋黑鮪 (Thunnus orientalis),特別是在六、七月熟肉發生機率明顯增加,夏季較高的水溫被懷疑是造成里郭內之可能原因。雖然黑鮪熟肉現象在台灣發生已有相當時間,但是發生之原因及機制仍未被了解,本研究室經初步之生化分析顯示肌肉中有數種氨基酸分解，及酸度增加。,為更了解其原因及機制,我們嘗試了解東港整個黑鮪產業作業流程,嘗試找出可能產生黑鮪熟肉之原因。希望能降低漁業損失,增加海洋資源之利用。
由於目前並非黑鮪產季,本調查為研究之前置分析,目的在網羅發生黑鮪熟 肉之所有可能因子,作為日後研究之方向,並以訪談之方式做調查。訪談期間為 2013年9月至12月,訪談之對象以黑鮪漁業相關業者為主,包含船長、漁船作 業員、黑鮪肢解業者、黑鮪買賣業者,生魚片業者、餐廳業者、行政管理者等。 訪談內容包含黑鮪生態、捕捞方式、處理方式、保存方法,運方式,產生熟肉之可能原因等。
經訪談黑鮪相關業者後發現,可能產生黑鯛熟肉問題之原因相當多元化。高 水溫與處理不良被認為是發生黑鮪熟肉有最大可能性,其餘如死亡時間。 肌肉油脂量,死前掙扎。溫度管理、 黑鮪個性、黑鮪品系、潮汐、日月週期等均有 相當之關聯性。將以此調查資作研究之方向,於黑鮪產季時持續觀察及求證相關可能發生黑鮪熟肉因子。
在海洋資源逐漸枯竭之際,希望能找出鮪類發生熟肉之原因,降低漁業損失, 讓海洋資源能夠發揮最大效應。

| 摘要： | Crabs and shrimps have been popular eatables and important aquaculture species in Taiwan. Those crustaceans have distinctive flavors and high protein contents as good meats. The characteristics of muscle proteins are known to be greatly different to fish species. Among them, we have been working on fish muscle tropomyosins (TMs), revealing their species-specific differences in stability. Invertebrate TMs are known to be clearly different from vertebrate ones. Crustaceans TMs were seem as a common antigen for man. The amino acid sequences of TMs were different among species, so it shown the various polarity and charge-containing. However, it was found to be hard to purify invertebrate TMs by the conventional method for fish TMs. TMs from the black tiger prawn Penaeus monodon, giant freshwater prawn Macrobrachium rosenbergii, mangrove crab Scylla serrata and red spotted swimming crab Portunus sanguinolentus caught along the coast of Taiwan were purified by the combination of ammonium sulphate fractionation, continuous- and step-wise ion-exchange chromatography and dialytic precipitation. The results were shown that the TMs from crustaceans were different in molecular weights (33~37 kDa) and affinity to anion-exchange resins. This implies that the proteins were difference just for limited amino acids displaced. The 2D-PAGEs were shown Crustaceans TMs with a major spot and might not have isoform TM in muscle. It was easy eluted by potassium chloride solution from 165mM~ 215mM. We have further explored optimal conditions for the purification of TMs. |

| 摘要： | 台灣位處熱帶、亞熱帶。古來即為瘧疾、登革熱等熱帶蚊蟲媒介疾病盛行區域。近年來醫藥衛生的發達與普及，已經大為降低蚊蟲媒介疾病之盛行率。然而過度使用化學性藥劑滅蚊之結果，也造成生態嚴重之破壞及失衡。目前國際社會盛行有機天然方式代替人工化學方式，這種風氣不但在病蟲害防治、土壤改良等技術外，在防治蚊蟲上也逐漸被重視。天然植物中有些天然除蟲成分，利用這些特性，降低環境之蚊蟲量，如何讓來園的遊客在炎炎夏日中享受園區的景觀設備而不被蚊蟲叮咬，是許多主題樂園、花園重要的課題之一。
本研究採用坊間盛傳具有除蟲效果之草本植物-香葉天竺葵(Pelargonium graveolens)、迷迭香(Rosmarinus officinalis)、薄荷(Mentha spicata)作為研究對象，分析並比較這三種植物的驅蚊效果之成效。為能適用於休閒遊樂區之應用，採用實際樣區研究方式。研究方法如下：選定一基地分為實驗區與對照區，栽種不同實驗植物並以相同方式之捕捉法與計量方式，看蚊蟲族群種類數量及消長方式。經由數學模式之統計分析三種驅蚊植物之效用。
由初步成果顯示，香葉天竺葵(Pelargonium graveolens)、迷迭香(Rosmarinus officinalis)、薄荷(Mentha spicata)均有驅蚊之效果，至於何者成效較佳，什麼物質具驅蚊效果則需進一步分析討論。
希望研究成果對於蚊蟲防制有所助益，並減少熱帶蚊蟲媒介疾病之盛行率，讓大家有個安全又快樂的夏天。

| 摘要： | Bathynomus 是分佈在太平洋、大西洋和印度洋深海海床的甲殼類動物。根據文獻，於台灣、日本附近海域至少有三種Bathynomus，包括 B. doederleini 、B. decemspinosus 和 B. jamesi 。此屬物種間形態差異非常小，難以作為分類依據，為精確鑑定這些物種，COI 、16s rRNA 被作為標記，做DNA 比對及親緣關係建立，希望能建立 Bathynomus 分子生物學分類之依據。
向漁民購買產於台灣大渓、東港、台東及外島東沙島附近的Bathynomus 樣本，以 75% 的酒精保存。形態比較透過拍照紀錄。從足部肌肉中萃取DNA ，進行COI 、16s rRNA 的序列研究，並用 MEGA 11 繪製親緣關係。

| 摘要： | Bathynomus是分佈在太平洋、大西洋和印度洋深海海床的甲殼類動物。根據文獻記載在台灣、日本附近海域至少有三種Bathynomus，包括 B. doederleini、B. decemspinosus和 B. jamesi。Bathynomus的分類以形態學作為主要分類依據，其中尾棘（Pleotelsonic spines）、尾棘中央脊 (Pleotelsonic central spine)、泳足上剛毛 (Uropod exopod setal)、眼上脊 (Ridge above eyes)、頭楯側緣 (Clypeus lateral margins) 、前額板 (Frontal lamina) 等性狀做為分類依據。由於 Bathynomus 型態分類複雜，在 B. doederleini 及 B. jamesi 上發現許多分類上有問題的地方。
向漁民購買產於台灣大渓、東港、台東及外島東沙島附近附近捕獲的 Bathynomus 樣本，以 75% 的酒精保存。形態比較透過拍照紀錄，並以外觀形態分類比較。
根據此物種形態鑑定並使用檢索表分類 (Lowry and Dempsey, 2006)；發現台灣（大溪、東港、台東及外島東沙島）捕獲的 B. doederleini 及 B. jamesi ，同物種間有尾棘數量不同的現象，造成分類上的困擾。這個結果挑戰了 Lowry and Dempsey, 2006 對於Bathynomus 以尾棘數作為分類依據之標準，顯示分類表有修正檢討之必要。

| 摘要： | Bathynomus species are deep-sea crustaceans distributed in the deep ocean floor of the Pacific, Atlantic and Indian Oceans. According to the references, there are at least three species of Bathynomus in the South China Sea, including B. doederleini, B. kensleyi and B. jamesi. The differences between the species of genus Bathynomus are very small and not easily distinguished based on the morphology (Fig. 1, Table 1). The upwardly curved pleotelsonic spines are often considered to be the characteristics of B. kensleyi by the Taiwanese media. To identify the species, we used COI gene of the mitochondrial DNA as the marker.
The three samples were collected from Zhengbin Fishing Port in Keelung, Taiwan on 17 July, 2019. According to the information from fishermen, coupled with the GPS record of the fishing vessel involved, these samples were captured in waters of the Pratas Islands about 430 km south-west of Kaohsiung, Taiwan. The genomic DNA was isolated from the pereopods muscle. The primers were designed based on the sequences of the conserved regions of COI. The PCR-amplified products were sequenced using a DNA sequencer.
The sequences of COI from the three individuals collected from Pratas Island waters were almost identical to that of B. jamesi collected off Hainan Island, China, in 2017, instead of B. kensleyi. Because both B. kensleyi and B. jamesi have the upwardly curved pleotelsonic spines, molecular biological identification is thought to be essential for their identification.

| 摘要： | 海神後海螯蝦Metanephrops neptunus (Bruce, 1965)屬於後海螯蝦屬（Metanephrops）蝦種，於1965年在南中國海域首次發現，漁民稱其為「金絲猴」或「紅頭龍蝦」，在澳洲則被稱為尼普頓龍蝦（Neptune lobster）。
本實驗樣本於2019年7月採自宜蘭正濱漁港之漁民，共計有三隻雌性與七隻雄性個體，全長介於23~28公分，重量介於272~505公克之間，測量後進行拍照及蝦體外觀描繪。
觀察結果發現雌、雄個體擁有相近的顏色–紅色的頭胸甲和乳白色腹節。在胃中發現底棲多毛綱動物、線蟲類和甲殼類殘渣。在頭胸甲上有均勻的小刺以及在與額後龍骨瓣(postrostral carinae)之間有較大的刺狀凸起為此種分類關鍵。本次發現之海神後海螯蝦為台灣新紀錄種，為東沙群島漁業資源之一，期望可作為管理漁業資源的參考。

| 摘要： | 櫻花蝦(Sergia lucens)是東港重要的產業之一，與黑鮪魚、油魚子被稱為東港三寶。櫻花蝦是珍貴之資源，在日本是極為昂貴之水產，國人常曬乾食用。捕撈時期為每年之十一月至翌年五月，漁期可達半年之久。捕捉櫻花蝦目前以小型底拖網為主，而且櫻花蝦體型精小鈴攏，捕撈之漁網網目也相當細小，所以大小魚類乃至於各種仔稚魚也不放過，對海洋生態之危害甚大，雖然對外宣稱有自我管理與調節機制，但年年下降之櫻花蝦漁獲量卻是此項資源嚴重之隱憂。捕撈櫻花蝦產生之混獲問題也極為嚴重，卻未被社會大眾關心過，混獲之下雜魚可能遠比櫻花蝦之產量為大，種類包羅萬象甚至有許多新種之出現。最常見的種類包含各種類之燈籠魚、深海鯊魚、底鱈、甲殼類等。本研究調查櫻花蝦產季採集櫻花蝦混獲之生物種類，希望在櫻花蝦產業崩潰之前留下一份混獲魚種之資料，更希望能有更多學生、關懷海洋人士參與此議題，並喚起大眾對於海洋資源之珍惜與重視。

| 摘要： | 「龍」在中國是重要的象徵。東漢許慎在《說文》曾經解釋龍為「鱗蟲之長。能幽，能明，能細，能巨，能短，能長；春分而登天，秋分而潛淵」。 《左傳》記載：「昔叔安，有裔子曰董父，實甚好龍，能求其耆欲以飲食之，龍多歸之。」可知龍並非虛幻之物。由「龍」字來看，左半邊為頭部，右半邊為身體，屬於象形文字。古代人民所指的龍是什麼呢?而龍的原型是什麼生物呢?為瞭解開此謎題，研究中國最早古文字所記錄之生物特徵是一個重要的線索。
利用古文字學字型，分析其生物特徵。並利用生物分類學之基礎，將古人記載「龍」字的特徵與現今生物做比對。
根據中國古籍所記述「龍」的特徵，歸納出最接近之四種生物為蛇、鱷、蜥蜴及鱘魚。目前學界普遍認為龍的原型以「蛇型說」和「鱷型說」最為有力，兩派學說均有合理解釋。根據已解析所知甲骨文「龍」字所傳達生物特徴如下：身體呈長條形、無足、頭部巨大、擁有二巨牙、頭部能昂起等特點，排除了鱷魚、蜥蜴(無足)和蟒蛇、鱘魚(無巨牙)。顯然巨大毒蛇是「龍」的原型，在中國是巨大毒蛇又同時具有膨大頭部特徵者，眼鏡王蛇是最可能的種類。中國在商朝以前稱呼「龍」，極有可能是現今生長於中國南方的眼鏡王蛇。

| 摘要： | [目的]圓吻鯝 ( Distoechodon tumirostris ) 屬鯉科圓吻鯝屬 ( Distoechodon ) 魚種，分布於台灣北部及中國南部，主要棲息在淡水河川與湖泊中下層水域，但繁殖季時會溯溪產卵。由於是河流性淡水魚類，本研究希望透過將圓吻鯝調節肌肉收縮的原肌球蛋白( Tropomyosin, TM )與生活於激流與緩流之其他鯉科魚類比較，藉以探討環境適應對圓吻鯝肌肉演化的影響。
[方法]本實驗取魚背部骨骼肌，抽取total RNA，利用反轉錄聚合反應獲取TM之cDNA，再使用聚合酶連鎖反應放大片段，送定序儀定序核苷酸序列，並預測其演繹胺基酸序列。並使用已定序之核苷酸及胺基酸序列，利用MEGA軟體分析與其他魚類之親緣關係。
[結果]本研究定序圓吻鯝肌肉TM共855個核苷酸序列，演繹胺基酸為284個，結果相似於其他魚類背部肌肉TM胺基酸數量。將此序列與其他已知魚類TM序列做比對後發現：圓吻鯝與生活於激流的台灣石魚賓( Acrossocheilus paradoxus )、台灣白甲魚 ( Onychostoma barbatulum ) 和生活於緩流的斑馬魚 ( Danio rerio )、鯽魚(Carassius auratus) 等魚類肌肉相比，圓吻鯝TM與激流魚類較為相似。推測其原因可能是圓吻鯝為了適應河川激流及溯溪繁殖演化而成，雖然圓吻鯝平時生活於緩流但其TM結構與分佈於激流的鯉科魚類較為接近。此結果應證了環境因子會影響魚類表徵之理論。

| 摘要： | 彈塗魚是常見於河口及溪流泥灘地和溼地的魚類，在環境中是許多鳥類的食物來
源，同時也能當作是辨別環境好壞的生態指標，但是對於彈塗魚的很多生態行為並沒
有太多的解釋。本篇在於探討彈塗魚求偶行為與生態習性，一般人的認知中，大彈塗
魚的求偶行為就是彈跳起來。為了要觀察大彈塗魚的求偶行為，時間選在
6月中正值彈塗魚求偶期，地點選在高雄茄萣白砂崙濕地，我們利用攝影機在每次乾潮前一小時，
以及滿潮前一小時架在岸邊拍攝2個小時至3個小時。觀察結果發現彈跳只是所有求偶
行為中的一部分而已，而求偶行為大致上可以分為三部分，第一部分是彈跳、第二部
分是擺尾，最後則是引導，每個動作都有其意義。而我們本次的結果在高雄茄萣的白
砂崙濕地，同時也發現了青彈塗魚的蹤跡，青彈塗魚在水位高時，出現的頻率較多，
所以推論青彈塗魚對水的依賴程度比大彈塗魚還要高，對溫度的耐受性比大彈塗魚還
要低。大彈塗魚的求偶行為經研究後，比一開始認知的還要複雜，而台灣青彈塗魚的
發現紀錄大多是在新北市的挖子尾自然保留區，南部相對較少，大彈塗魚的外觀與青
彈塗魚極為相似，而唯一最大的不同在於第一背鰭的外觀，大彈塗魚的第一背鰭是扇
形，青彈塗魚的第一背鰭則是旗桿狀，所以不仔細看是無法分辨其差異。 |

| 摘要： | 《詩經》是中國最早的詩歌總集及純文學專著，收錄了西周初到春秋中期(西元前一千年至西元前四百年)約六百年間的文學作品。詩詞忠實呈現當時人民的生活方式、觀念與民間習俗，所以是研究漢族文化與風俗重要參考著作。
《詩經》中記載許多生物種類，其中三分之一以上內容提到植物，反映了當時漢族環境與可利用的生物資源。而魚的記述與人民的生活、宗廟祭祀息息相關，《詩經》中也常提及，其中有關大魚的記述常出現「鱣」、「鱏」、「鮪」等魚類。漢族在遷徙擴張的過程中，受到地域、方言、傳抄及錯誤解釋下產生許多異名或錯誤。為了瞭解古代《詩經》魚類現今學名，本研究根據《詩經》及注疏所描述之生物特徵作為魚類分類學之依據，除確立今日學名外，也將探討分布範圍。
經《詩經》及注疏所描述魚類特徵分析顯示；「鱣」、「鱏」、「鮪」均是當時出產於黃河流域江河中的大魚，以今日學名而言，「鱣」為中華鱘(Acipenser sinensis)，而「鱏」和「鮪」所描述特徵均指向白鱘(Psephurus gladius)。根據古文獻記載，白鱘和中華鱘曾分布在廣大的漢人活動區，然而今日上述兩種大魚均成為瀕臨絕種之珍稀魚類。這些曾和漢民族祖先有相當接觸的魚類，現在的我們已不再熟悉它，白鱘可能已經絕滅。
《詩經》中將「鱣」和「鱏」分辨得很清楚，是兩種外型結構截然不同的魚類。然而今人卻將「鱣」和「鱏」混為同一種「鱘」類。建議中華鱘應該正名為中華鱣，而今日常用的「鱘」即是古字「鱏」，就是指白鱘一種魚類。本論文目的在確認古文中的魚類，還原並瞭解漢人生活中利用這些魚類的歷史。

| 摘要： | 北宋年間，北方的游牧民族契丹分布於今中國東北及蒙古廣大地區，於西元907年由耶律阿保基建立遼王朝。遼與宋之間由於環境及民族的不同，產生許多文化差異。《遼史》記載遼國君主常在初春河川上「鉤魚」，遼國君主鉤什麼魚？宋‧武珪《燕北雜錄》中記述：「北虜於達魯河鉤牛魚。」北虜指蒙古人，達魯河為今東北吉林省扶余縣松花江、嫩江交接處，而「牛魚」是指什麼魚呢？
歷史文獻中，有數種關於牛魚究竟是何魚的討論。宋‧王易《燕北錄》云「牛魚觜長鱗硬，頭有脆骨重百斤，即南方鱏魚也。」又云「牛魚即鱘之大者。」明‧方以智《通雅》「牛魚，北方之鮪類也。」也認為是鱏魚。明‧李時珍《本草綱目》引陳藏器「牛魚生東海，其頭似牛」，既有鱘魚，又載牛魚，所以李時珍認為鱘魚和牛魚並非同種生物。清‧紀曉嵐《閱草堂筆記》「金重牛魚，即瀋陽鱘鰉魚，今尚重之。」可見牛魚一詞有不同的解釋。
本文考察遼、宋以後有關牛魚記載的文本，並對照古代文獻描述的生物特徵，大膽推測「牛魚」一詞在不同的朝代及地域指不同生物，屬於異物同名的例子。曾在歷史上被稱為「牛魚」的生物可能包含白鱘（Psephurus gladius）、達氏鰉（Huso dauricus）、儒艮（Dugong dugon）、虎鯨（Orcinus orca） 、六鬚鯰魚（Silurus glanis）等。《遼史》所指牛魚，以白鱘（Psephurus gladius）之可能性最高。本文在通識課程中，能結合教學與研究，進行人文社會科學與自然科學的對話。
在北宋年間，契丹是北方的游牧民族，分布在今中國東北及蒙古廣大地區。契丹族在西元907年由耶律阿保基建立遼王朝。由於環境及民族不同，遼與宋有許多不同的文化。其中在《遼史》記載遼國君主常在初春河川上「鈎魚」。遼國君主鈎什麼魚?在宋武珪《燕北雜錄》中記述；「北虜於達魯河鈎牛魚。」北虜指蒙古人，達魯河為今東北吉林省扶余縣松花江、嫩江交接處。宋程大昌《演繁露》也記載「達魯河鈎牛魚，遼地盛禮。意慕中國賞花釣魚然，非釣也鈎也。」而「牛魚」是指什麼魚呢?
在推測牛魚可能的魚類之同時，首先對遼國君主鈎牛魚之目的需作一些說明。契丹人是游牧民族，對於打獵漁撈相當重視。頭鵝宴及頭魚宴及是皇帝重視漁獵知識的表徵，有如以農立國的漢族君主祭祀五穀之神的涵意。頭魚宴如何舉行?契丹皇帝常會在春來江河解凍之前在群臣護衛下到春捺缽地先鑿冰鉤魚，之後再縱鷹鶻捕雁鵝。頭魚是一年中第一次獲得的魚，顯得極為貴重，再由君主設酒宴宴請全臣，為契丹族的盛禮。此頭魚一定是貴重而大的魚，由於是大魚，無法用釣魚的方式，所以是用鉤的。根據脫脫《遼史》記載，遼國君主鉤魚的地點最常在土河(老哈河)、鴨子河(松花江)、混同江(第二松花江)等地。這些區域有哪些大魚且是高貴可進貢給皇上的呢?許多文獻清楚的紀錄這種魚類稱之為牛魚。
歷史上針對牛魚有過各種描述；宋李昉《太平御覽》卷九三九鱗介部引《臨海異物志》云：「牛魚，形如犢子，毛色青黃。好眠臥，人臨其上，及覺，聲如大牛，聞一里。」三國魏武《四時食制》曰：「海牛魚皮、生毛可以飾物，出揚州。」晉張華《博物志》曰：「東海中有牛魚，形如牛。剝其皮懸之，潮水至則毛起，潮去則伏。」宋王易《燕北錄》云「牛魚觜長鱗硬，頭有脆骨重百斤，即南方鱏魚也。」又云「牛魚即鱘之大者。」宋周必大《二老堂雜誌》「賛寧《物類相感志》引《博物志》云：「東海有牛魚，其形似牛，剝其皮懸之，潮水至則毛起，退則毛伏。今東牟有海牛島，其牛無角，足似龜，長丈餘，尾若鮎云。」明李時珍《本草綱目》引陳藏器曰「牛魚生東海，其頭似牛。」以上之敘述，可以發現對牛魚有不同之詮釋。
本研究主要蒐集遼宋以前有關牛魚記載的文本，並對照古文描述之生物特徵，推測「牛魚」一詞在不同的時期及地域指不同生物。在宋朝以前漢族描述的牛魚以海牛類之海中哺乳動物為主，宋朝以後北方契丹人建立遼國後，漢人受到遼人習慣影響，也將漢族習慣稱為鱏的江中大魚稱為牛魚。曾在宋朝以前被稱為「牛魚」的生物可能包含白鱘(Psephurus gladius)、達氏鰉(Huso dauricus)、儒艮(Dugong dugon)等。而《遼史》所指牛魚，以白鱘(Psephurus gladius)之可能性最高。

| 摘要： | 原肌球蛋白(tropomyosin,TM)為一種與肌鈣蛋白(troponin)形成肌鈣蛋白複合體的蛋白質，藉由與肌動蛋白(actin)的結合來調節肌肉之收縮。原肌球蛋白是由兩股α-螺旋的多胜肽鏈纏繞而成的結構。臺灣石魚賓(Acrossocheilus paradoxus)屬光唇魚屬(Acrossocheilus)，體側具7條黑色橫帶，幼魚較成魚明顯，為台灣特有種魚類，普遍分布於台灣河川溪流中。由於熱帶魚類原肌球蛋白肌肉特性研究較為缺乏，臺灣石魚賓為台灣特有種類，對於研究肌肉結構及與其他魚種作比對有相當的研究價值，此次以肌肉結構中較易研究之原肌球蛋白作為探討之對象。自花蓮XX溪中捕捉野生石魚賓，從活體取魚背部的骨骼肌，抽取total RNA，利用反轉錄聚合反應獲取原肌球蛋白之cDNA，再使用聚合酶連鎖反應(PCR)放大片段，最後送入定序儀定序出核苷酸及演繹胺基酸序列，利用蛋白質模擬系統推測其蛋白質立體結構。由結果得知臺灣石魚賓原肌球蛋白其分子量約33000Da，284個胺基酸序列，N端和C端序列皆有高度保留的現象。原肌球蛋白的研究有助於比較不同物種肌肉運動上的差異，也可藉由其基因序列上的差異來進行物種親源的研究。 |

| 摘要： | 原肌凝蛋白 (Tropomyosin, TM) 廣泛存在於動物肌肉與細胞骨架中，在肌肉收縮與細胞內物質移動上扮演重要的角色。多年來許多研究指出TM蛋白是甲殼類中主要的過敏原，解開TM蛋白的過敏致病機轉有助於減少過敏症狀發生，而純化出高純度的TM蛋白有助於TM蛋白物理化學性質的研究。傳統對於魚類TM蛋白的純化方式並無法有效從組織中分離出TM蛋白，甲殼類肌肉蛋白有不同的化學性質且TM蛋白分子量也較大。本研究結果顯示出，蝦類TM蛋白可利用30% 硫酸銨分畫分離出TM粗蛋白，蟹類則是在26%處有較好的分離效果。陰離子交換樹脂管柱層析結果顯示，白蝦非TM蛋白在沖提液濃度90 mM KCl處分離，TM蛋白在135 mM KCl處分離。紅星梭子蟹 (Portunus Sanguinolentus) 及鋸緣青蟹 (Scylla Serrata) 的非TM蛋白隨著flow through分離，TM蛋白則在215 mM KCl處分離。此外本實驗嘗試利用透析沉澱法分離白蝦TM蛋白及非TM蛋白，取得初步的成果，值得深入研究。

| 摘要： | 熟肉 (burnt meat)是一種異常肉，常發生在鮪類等大型魚類肌肉。「熟肉」顧名思義就是像煮熟過的肉，肉色顯得較亮白，口感缺乏彈性，味道比正常肉呈現酸性。台灣四月至七月為捕捉太平洋黑鮪 (Thunnus orientalis) 之季節，端午節之後，黑鮪熟肉發生率增加，造成漁民莫大損失。然而黑鮪熟肉發生之機制至今未明，問題也未被解決。本研究嘗試比較熟肉與正常肉之生化特性。於2014 年五月至七月蒐集東港黑鮪熟肉樣本三十件，經初步實驗分析結果如下；肌肉組織酸度增加(熟肉5.56±0.1，正常肉5.97±0.1)，顏色變得較蒼白 (L值熟肉39.34±3.6，正常肉30.03±4.5)。利用15% SDS-PAGE 電泳發現熟肉在50 KDa 有蛋白質降解。另作肌肉組織之TBARS 值實驗顯示熟肉過氧化程度比起正常肉來的高 (31.27±19.79 vs. 9.41±7.17)。本研究顯示熟肉現象包含許多蛋白質分解過程，與溫度、酸鹼度及時間有關連，將進一步模擬熟肉發生之機制。

| 摘要： | 鯊魚在海洋生態中扮演高層掠食者的角色，如同陸地上獅、虎等地位，具有穩定海洋生態、維持物種多樣化之功能。由於鯊魚之生態特殊，繁殖後代個體數少，族群回復之能力相對較弱。然而國人嗜食魚翅，婚慶宴席更少不了魚翅，加深了鯊魚被人類濫捕之命運。美國最大的魚翅消費市場加州已於2012年1月1日起禁止販售魚翅，其目的在於維護海洋生態與生物之多樣性。東港是台灣重要之鯊魚卸貨漁港，在臺灣有重要之地位。本調查在了解東港地區鯊魚利用之情形，了解魚翅使用鯊魚之種類、學名、地方名與魚翅名等基本資料，希望能作為了解此一產業之依據，並希望藉此傳達鯊魚生態之重要性，維護海洋生態。 |

| 摘要： | 櫻花蝦是東港重要的產業之一，與黑鮪魚、油魚子被稱為東港三寶。櫻花蝦是珍貴之資源，在日本是極為昂貴之水產，國人常曬乾食用。捕撈時期為每年之十一月至翌年五月，漁期可達半年之久。捕捉櫻花蝦目前以小型底拖網為主，而且櫻花蝦體型甚小，捕撈之漁網網目也相當細小，所以大小魚類乃至於各種仔稚魚也不放過，對海洋生態之危害甚大，雖然對外宣稱有自我管理與調節機制。但年年下降之櫻花蝦漁獲量卻是此項資源嚴重之隱憂。捕撈櫻花蝦產生之混獲問題也極為嚴重，卻未被社會大眾關心過，混獲之下雜魚可能遠比櫻花蝦之產量為大，種類包羅萬象甚至有許多新種之出現。最常見的種類包含各種類之燈籠魚、深海鯊魚、底鱈、頭足類、甲殼類等。本調查在記錄櫻花蝦產業混獲之種類，希望在櫻花蝦產業崩潰之前留下一份混獲魚種之資料，更希望能有更多學生參予此議題，並喚起大眾對於海洋資源之珍惜與重視。 |

| 摘要： | 魚類是脊椎動物中種類最多的一個族群,而鱸形目 Perciformes)魚類更是硬骨魚類中最大的一個分群,其具有許多種類不同但外型相當接近的魚類,且在基因的表現上也相當的多元化, 因此物種鑑定及分類的研究變成一個重要的課題。
原肌球蛋白(tropomyosin, TM)是一種廣泛存在於各種生物的蛋白,其蛋白質 N端及C端具有相當的保守性,且從原始的微生物到脊椎動物均可發現它的存 在。動物的 TM 最常見於肌肉中的纖維,其扮演著與肌動蛋白(actin)、肌凝蛋白 (myosin)相互協調並促進肌肉調節與收縮之重要角色。由於TM具有高度保守並 廣泛存在高、低等生物肌肉中的特性,因此有作為分子標記的可行性。目前TM 在魚類物種鑑定及分類上的研究相當稀少,且多以不同目之魚類作較廣範圍的研 究,因此本研究嘗試以TM蛋白及DNA作為分子標記,利用資料庫中已登錄肌肉 TM 胺基酸及DNA序列之鱸形目魚類,以計算(calculation)與模擬(simulation) 之系統生物學方法,分析鱸形目中不同魚類親緣關係的遠近,探討生物差異性在生態及適應上之意義。
由分析結果發現無論在DNA或蛋白質序列上皆有相異之處,可能與演化及環境適應有相當程度的關聯。本研究希望能以TM 為觀點,在物種鑑定及分類的研究中建立一個新的指標。

| 摘要： | Tropomyosins (TMs) are not only found in muscle fibers but also in non-muscle cells. They are wildly existence in eukaryotes. TMs are composed of two subunits (approximately 33 kDa), and forms a coiled-coil structure which consisting of two parallel α-helical polypeptides. They are associating with myosin complex and actin on the thin filaments of striated muscle. Some references describe human allergic reaction is caused by crab’s TMs. In this study, three crabs like mangrove crab (Scylla serrata), blue swimmer crab (Portunus pelagicus) and corab crab (Charybdis feriata) for the samples. We use high speed centrifugation, ammonium sulfate saturation and isoelectric point to find the best purified condition of crab’s TMs. On the next step, we will use the TMs and try to look for mechanism of human allergic reaction caused by carb’s TMs. |

| 摘要： | Small abalone (Haliotis diversicolor) is a species of marine gastropod mollusk in the family Haliotidae and the genus Haliotis. It has widespread distribution, include coastal waters of
Boso Peninsula, Kyushu, Korean Penin-sula, south China and Taiwan. It is an important organism for fishery in Taiwan. Tropomyosin (TM) is widely distributed in all cell types asso-
ciated with actin as a fibrous molecule composed of two α-helical chains arranged as a coiled-coil. Molecule mass of TM in the muscle cell is 33 kDa and containing 284 amino acids,
it can regulate muscle contraction by interaction with actin and myosin. The perpous of this study is to confirm the method of purifi-cation of TM. We used ultracentrifugation, isoele-
ctric point, and salting out with ammonium sulfate to extracting the crude TM from small abalone skeletal muscle. Then we purified TM by column chromatography and detected its
cha-racteristics by electrophoresis gel analysis. We hope this study can be useful for protein structure study. |

| 摘要： | Tropomyosin (TM) is a kind of muscle protein which wildly exists in eukaryotes, associating with troponin to form a complex and then binding with actin to regulate muscle contraction. Currently, the molecular weight of TM in vertebrates like human, rabbits, and fish is known near to approximately 33 kDa, and consists of 284 amino acid residues. In recent study, it is found out that TM in invertebrates is allergen of food allergy and most of the studies are about crustaceans such as crabs and shrimps; however, there are less studies regarding other invertebrates. In this study, we choose a species of cephalopoda - octopus (Octopus vulgaris) as our sample, which is one of invertebrates to understand the biochemical features of muscle TM so that we can compare with vertebrates. In this study we refer to known purification conditions of TM. We use some biochemical methods like high-speed centrifugation, ammonium sulfate saturation and isoelectric point to purify the cephalopodous TM. We wish this study can benefit to food-processing and medical fields. |

| 摘要： | Tropomyosins (TMs) form a family of actin-binding proteins that are highly conserved throughout evolution. They are found not only in muscle fibers but also in non-muscle cells. The TM is composed of twoα- subunits (approximately 33 kDa), and forms a coiled-coil structure consisting of two parallel α-helical polypeptides, which associate with troponin complex and seven actin monomers on the thin filaments of striated muscle. We are interesting in some invertebrate TMs because reference is limited and major research focus on allergen. The TMs of crustacean like shrimps and crabs are quietly different from vertebrate. To find the purified methods of crustaceous TMs is very important for next research. In this study, we used Black tiger prawn (Penaeus monodon), Giant freshwater prawn (Macrobrachium rosenbergii), Pacific white shrimp (Litopenaeus vannamei), Shiba shrimp (Metapenaeus joyneri), Mangrove crab (Scylla serrata) and Red spotted swimming crab (Portunus Sanguinolentus) as samples. We used high speed centrifugation, ammonium sulfate saturation, isoelectric point and column purification and try to find the best condition to purify the crustaceous TMs. |

| 摘要： | Mudskipper, which is also named “Spotty-bounce” or “Mud-monkey”, is common in mangrove marsh regions of Taiwan. The mudskippers commonly found in western coast of Taiwan are Periophthalmini boleophthalmus and Periophthalmus
cantonesis. This mudskipper species amphibian, it can breathe with its moist skin and the moisture in the gill chamber, and adapt to life in a semiwater-landed shore. It can construct vertical underground tunnels in bayou, marsh, and mud shoal,
and inhabits within. Because of the bouncing character of mudskipper and the oxygen-changing living condition, we are interested in the structure of the mudskipper`s muscle.In this study, we focus on the highly conserved muscular fibril – TM
of whole muscle. We probe into the structure and the thermostability of the skeletal TM of mudskipper, and compare and analyze the data from mudskipper with other species. Firstly, we extract TM molecules using isoelectric precipitation,
high speed centrifugation and ammonium sulfate saturation. Next we identify the extract of TM by SDS-PAGE and 2D-SDS-PAGE. Finally we analyze the thermostability and the 3-D structure using by differential scanning calorimetry (DSC)
and circular dichroism (CD) spectrometry; respectively. The data acquired from mudskipper were compared with other fish.We found that the structure of mudskipper TM is different from other species and the thermostability is higher.
Although we can not prove that the results are caused by the amphibious situation, this truely provides a new direction for subsequent studies. We hope that this research adds to the knowledge about the living styles of animal in everglade and
how these animals adapt physiologically to the environments. Furthermore, the study provides insight to the significance of biological diversity and evolution. |

| 摘要： | 台灣西南沿海廣佈濕地地形，潮間帶泥地常有一些特殊的生物。彈塗魚是此區常見的
兩棲魚類，具有特殊適應濕地的型態及生態結構。長久以來大家都知道彈塗魚是會築巢的
，築巢的行為除了提供彈塗魚在漲退潮時的棲息地外，在求偶行為、逃避敵害，溫度調節
等生態意義也是重要的一環。但卻鮮少有人知道彈塗魚巢穴的形狀，國內外有關彈塗魚巢
穴的文獻也相當有限。本次調查以分布於台南四草地區彈塗魚為主要探討對象，針對其巢
穴形狀作一調查，探討其生態之意義。經野外採樣調查發現，台南四草地區以廣東彈塗魚
(Periophthalmus cantonensis)為主要魚種。選定退潮時彈塗魚巢穴洞口裸露時，先趕走巢穴
內之彈塗魚，利用道具吸乾巢穴內水分，再利用固形劑注入該巢穴中，待凝固後挖出模型
，探討彈塗魚巢穴模式及生態功能。經數個彈塗魚巢穴模型取出後發現；廣東彈塗魚的巢
穴基本樣式如Y字型，巢穴甚深可達30公分以上，巢穴之型態具有多樣性，洞口至少有兩個
以上，通常一大一小。有時一個巢穴多達四個洞口。巢穴底部通常充滿水，退潮時在洞口
乾燥狀態下底部仍有相當保水性，調查中亦發現有巢穴底部直接與河底相連通者，顯示彈
塗魚巢穴的複雜性。這些研究希望能了解更多彈塗魚適應濕地之行為生態，並能有效管理
溼地資源。 |
