辽宁地区的淡水 虎鱼主要分布在辽河和鸭绿江两大河流。常见的大约有七种 ,多为小型鱼类 ,生活于底质为沙石的清流中。近年来由于生态环境的恶化和人为等因素的影响 ,使水环境因子和水生生物生长失衡 ,造成淡水 虎鱼难以生存 ,资源数量明显减少。 虎鱼在遗传学、人类食用、水环境监测等方面具有重要的作用 。
The freshwater goby is mainly found in Liao River and Yalu River in Liaoning.There are seven common kinds ,most of which are small ones,living in clear waters with sand and stone at the bottom.Recently because the ecology environment is getting worse,together with human actions etc,the elements and the living thing in water has lost balance.Naturally it has become hard for the freshwater goby to live and the number of it is getting smaller and smaller.This essay means to emphasize the attention to the protection and the use of the freshwater goby in terms of its functions in genetics,food for human, water conditions supervising.
