The feeding and excretion of three little fishes (Hemiculter. leucisculus, Tilapia. aurea and Cirrhinus. molitorelld) was studied and their effect on water quality of Qiankeng reservoir in Shenzhen City Around the topdown effect of fish was also studied. Based on the analysis of their stomach contents, their diet composition was assayed. The three fishes" feeding rhythm in cage and their rate of digestion indoor were looked into, and their daily ration was estimated through the method of daily average fullness index. Using the spectrophotometer, the content of chlorophyll a in the stomach was measured, and the feasibility of taking the chlorophyll a as an index of measuring the feeding of fish on phytoplankton was studied. Adopting the national standard method, the effect of the three fishes" excretion on total nitrogen, total phosphorus, CODMn, pH, turbidity and conductivity coefficient was surveyed. The effect of feeding and excretion offish on water quality was discussed and the results revealed as follows:H.

围绕鱼类的下行效应，本文以深圳茜坑水库三种小型鱼类Hemiculter leucisculus罗非鱼Tilapia.aurea和鲮鱼Cirrhmus.molitorella为研究对象，以胃含物分析为基础，分析了三种鱼类的食物组成；调查了网箱中自然状态下三种鱼的摄食节律，在室内调查了三种鱼的食物消化速率，运用日平均饱满指数法计算出三种鱼的日粮；采用分光光度法测定了鱼体肠叶绿素含量，探讨了叶绿素作为鱼类对浮游植物摄食量衡量指标的可行性；采用国家标准的水质测量方法，测定了鱼类排泄对总氮、总磷、高锰酸盐指数、pH、浊度和电导率的影响量。
