Using the methods of classical shape size measuring and chromosome analysis, we studied the morphological characters and Karyotype of Cobitis sinensis in Xiangjiang River. We also investigated the evolution line and Karyotype polymorphism of the C . sinensis by the methods of cytological classification and cytocatalytic. Our results suggest that the formation of chromosome polymorphism was concerned with heterologous hybridization and some of C . sinensis may perpetuate in a clonal manner by natural gynogenesis.
本文以湘江流域的中华花鳅为研究对象，运用经典的形态测量观察方法、染色体制片技术对中华花鳅的形态生态特征、染色体组型进行了初步研究：运用细胞分类和进化方法对中华花鳅的核型演化和核型多态现象的形成进行了分析，提出：其核型多态的形成牵涉到鳅科鱼类的异源杂交，某些中华花鳅可能是行雌核发育生殖的。

The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.
刺鳅，属鲈形目、刺鳅科(Perciformes，Mastacembelidae)，是广泛分布于中国南方的小型淡水鱼类。1998年，我室通过核型分析，首次发现该物种具有明显分化的异形性染色体，其性别决定类型为XX／XY型。1999年，本室通过染色体显带、精母细胞联会复合体观察，再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体，两者不仅已经出现结构异染色质分布上的不同，同时在外部形态上也存在明显差异，识别特征鲜明，在光镜观察下无需显带即能清晰辨认性染色体。

The basic diploid number of chromosomes in the family Cobitidae was deemed to 2n=50. The C . sinensis with 2n=40 may originate from the ancestor of the subfamily Cobitidae. The C sinensis with 2n=90 which reserved all of 40 original chromosomes maybe result from heterologous hybridization among some fishes of the subfamily Cobitidae. The C . sinensis with 2n=76 is probably a branch of hybrid offspring.
鳅科鱼类染色体的祖先二倍数是2n=50，2n=40的中华花鳅可能是由类似于泥鳅的2n=50的鳅亚科祖先经罗伯逊易位2n=50→48→40转变而来的。2n=90的中华花鳅保留了初始的40条染色体，它可能是由2n=40的中华花鳅与同为鳅亚科的其它鱼类杂交后演化而来的。2n=76的中华花鳅并非异源三倍体，它可能是杂交后演化的一个分支。

A flume experiment and a 2-D numerical model, TABS-2, were employed to simulate the hydraulic characteristics in fixed-bed condition. In addition, by selecting Gobioidi, Cyprinidae and Homalopteridae as the indicator species, the change of fish habitat and the habitat diversity for two different Froude number conditions were discussed.

鲤科鱼类包含3个主要的分支，即鱼丹系、鲤系和雅罗鱼系；但在非鲤科鲤形目鱼类中，其关系不能得到很好的解决，其中鳅科是复系，平鳍鳅科、条鳅亚科和花鳅亚科可能有较近的亲缘关系。
