The phylogenetic tree of fish IgH conserved region contains two major branches of teleost and elasmobranch, and snakehead IgH is most closely related to pufferfish. The phylogenetic tree of IgL conserved region shows three major branches, and snakehead IgL locate as a branch of IgL1A.

根据IgH和IgL恒定区氨基酸序列构建系统进化树，鱼类IgH形成硬骨鱼和软骨鱼两大分支，其中乌鳢IgH与河豚IgH的亲缘关系较近；硬骨鱼IgL系统树显示3个主要的分支：L1、L2和L3，乌鳢IgL位于L1分支的L1 A亚类。

The breeding scale of hybrid snakehead (Channa argus♂×Channa maculate♀)waslarger and larger in south of China. Three important factors witch lead to low survivalrate was studied, including prey density, stocking density and cannibalism.

杂交鳢是乌鳢父本和斑鳢母本，通过杂交获得的F_1代，在苗种培育时期易发生残食现象，常使存活率大大降低，严重制约了杂交鳢大规模养殖和推广。

The activities and distribution of digestive enzymes in the juvenile, young and adult stages of Chinese Snakehead Channa asiatica were studied. The results showed that activities of digestive enzymes increased with the development of C.

对月鳢稚鱼、幼鱼和成鱼的主要消化酶活性及分布进行了研究，结果如下：①随着鱼体发育和生长，月鳢消化系统各器官组织的各种消化酶活性不断地增强，尤其是蛋白酶和脂肪酶活性的发育更为明显。

The Triangle town of the agricultural sector and seed breeding of aquatic products in the relevant market with the help of fisheries experts, for the first time in Guangdong Province will be carried out and the area north of Hunan and Hubei and the snakehead Channa spot of Hong Kong to carry out research crossbreeding.

2000年起，三角镇农业部门和裕荣水产种苗繁育场一起在相关水产专家的协助下，首次在广东省开展了将两湖及以北地区的乌鳢与香港地区的斑鳢进行杂交育种的研究工作。

Gobbid fish Odontobutis potamophila (Günther was one kind of raptatorial benthonic fish in Taihu Lake.

河川沙塘鳢Odontobutis potamophila(Günther，Gobbid fish属鲈形目，塘鳢科，俗名塘鳢鱼，为淡水底栖小型野生肉食性鱼类，分布于我国长江水系中下游、钱塘江、闽江等水系。

The Odontobutis potamophila belongs to Perciformes, Odontobutidae. It is an important freshwater commercial fish in china.

河川沙塘鳢Odontobutis potamophila属鲈形目、沙塘鳢科，为我国重要的淡水经济鱼类。

Siniperca chuatsi and Channa argus are two fish species belonging to the same family Perciformes with the spiny eel, which both possess productive importance. So far there are no any reports about their sex chromosomes.

鮨科鱼种鳜鱼和鳢科鱼种乌鳢都是鲈形目的物种，具有较高的经济价值，是同刺鳅近缘的常见淡水鱼类，目前尚无有关两个物种的性染色体的报道。

When applied the spiny eel X chromosome library probes to the chromosomes of the two fish, different signals were distributed: in Siniperca chuatsi, besides some little signals on lot of autosomes, a large bright signal region was detected on the 8th chromosomes, which represented a synteny of spiny eel X chromosomes; but in Channa argus, no distinct synteny was found.

当以刺鳅的生物素标记X文库探针对鳜鱼和乌鳢的有丝分裂染色体进行染色体涂绘后，经过核型分析和统计分析表明，在这两种鱼的染色体上的杂交信号分布是不同的：在乌鳢中，除散在信号外，在其第八号染色体近着丝粒部位存在着一段较大的信号结合区域，应是与刺鳅的X染色体同源的保守同线群，而在鳜鱼中，只有散在信号分布于多条染色体上，没有明显的保守同线群存在。

Western blots were performed to investigate the cross-reactivity of various labeled antibodies with serum proteins from other fish species. Results Immunoglobulins of five fish species were purified, including bighead carp, carp, argus snakehead fish, ricefield eel, sea bass. The titers of five rabbit anti-sera obtained up to 1:32 examined by agarose double immunodiffusion. Five kinds of purified rabbit anti-fish immunoglobulins antibodies were labeled with HRP and their activities were up to 1:10000 examined by EUSA. Four kinds of rabbit anti-fish immunoglobulins antibodies labeled with HRP could react with serum proteins from other fish species.

结果 纯化了鳙、鲤、乌鳢、黄鳝、鲈五种鱼血清免疫球蛋白，免疫双扩散法测定兔抗这五种鱼免疫球蛋白的抗血清效价均达到1：32，并对纯化的兔抗鳙、鲤、乌鳢、黄鳝、鲈五种鱼类免疫球蛋白的抗体进行了HRP标记，ELISA测定标记抗体的效价达到1：10000左右，Western blots显示标记抗体与部分其他鱼类免疫球蛋白之间存在不同程度的交叉反应。

Our previous molecular cloning of snakehead fish GTH cDNAs revealed that the third cysteine residues is absent in shfFSH-β; instead, a positionally shifted cysteine is present at the N-terminus, as found in some phylogenetic related fish.

本研究已选殖鳢鱼脑下垂体GTH cDNAs，发现FSH-β次单元之第三个半胱胺酸并不存在，取而代之在N端有一多的半胱胺酸，由进一步资料分析发现鳢鱼相近鱼种亦有此特性。
