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.
