温度对链鳙鱼生理生化指标的影响

Effects of Temperatures on the Physiological and Biochemical Indexs of Silver Carp and Bighead Carp

鱼类属变温动物，温度对鱼类的生命活动有极为重要的影响。通过对鱼类血液红细胞、转氨酶及鱼体脂肪含量等指标在不同温度时的变化进行研究．通过目标规划方法的回归分析，分别得到了链鳙鱼在不同温度时各指标的上限值．这为研究火力发电厂温排水对鱼类的影响及制定温排水排放标准提供了重要依据．

A fish belongsto the group of cold-blooded animals. Its living activities are greatly influenced by temperature. The variations of some indexs such as a fish's red blood cells, transaminase and the contentsof a fish fat etc was dealed with, under different temperatures. By regression analysis based on the method of goal programming, we get upper limit values of these indexs of silver carp and bighead carp different temperatures. The result has a great effect on the study of the influence on a fish which is made by thermal wastewater from thermal power plants and it also provides an important foundation for working out the standard of drainage of,the thermal wastewater.
