The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。

The recover stage of testis development showed strong immunopositive reaction to aromatase antibodies, especially in spermatogonia and spermatocyte.

上述研究结果说明，睾酮、雌二醇及芳香化酶参与了大泷六线鱼精巢发育和繁殖内分泌功能调节。

Moreover, according to element compositions in mussels, these fishes were divided into three groups. The first group was characteristic with low phosphorus and high C/N ratio including Engraulis japonicus, Conger myriaster and Scomberomorus niphonius. The second had low phosphorus and low C/N ratio including fishes such as lower and middle carnivores such as Pseudosciaena polyactis, Platycephalus indicus and Argyrosomus argentatus. The third included some cold temperatefishes such as Scomberomorus niphonius and Liparis tanakae that were high phosphorus and low C/N ratio.

此外，根据鱼类的肌肉元素组成，将鱼类分为3类：第一类的主要特征为低磷、高C／N比值，主要包括鳀鱼、星康吉鳗和带鱼；第二类种类最多，主要包括小黄鱼、鲬和白姑鱼等中、低级肉食性鱼类，其元素组成特征为低磷、低C／N比值，；第三类的主要大泷六线鱼、细纹狮子鱼等冷温性鱼种为主，元素组成特点为高磷、低C／N比。

Any of various marine food fishes of the family Hexagrammidae, which frequent rocky coastal areas of the northern Pacific.

六线鱼，长蛇齿鱼六线鱼科的以海洋生物为食的任一种鱼，常见于北太平洋岩石海岸海区

Type genus of the Hexagrammidae.

六线鱼科的一个模式属。

Hexagrammos otakii is distributed mainly in the Bohai and Yellow Seas in China, and is a kind of important commercial Scorpaeniformes fish.

大泷六线鱼主要分布在我国的黄海和渤海水域，是北部海区重要的经济鱼类之一。

Moreover, fatty acid composition also indicated environment change. For example, cold temperatefishes such as Liparis tanakae and Hexagrammos otakii had more polyunsaturated fatty acids than warm species such as Pseudosciaena polyactis, Trichiurus lepturus and Scomberomorus niphonius.

此外，鱼类的脂肪酸组成还反映了生长环境的差异，冷温性鱼类(如细纹狮子鱼和大拢六线鱼)比暖水性鱼类(小黄鱼、带鱼和蓝点马蛟等)含有更高含量的高度不饱和月旨肪酸。

From September, 2004 to July, 2005, samples of Hexagrammos otakii were collected during 6 different periods, including spawning, post-spawning, over-winter, autumn, spring and summer in Dalian sea area.

以大连海区的大泷六线鱼为实验对象，于2005年9月至2006年7月期间，分别于秋季（9月）、春季（5月）、夏季（7月）3个季节和繁殖期（10月下旬）、繁殖后（12月上旬）、越冬后（3月）3个时期采集标本。
