克孜赛水库浮游生物与鲢、鳙鱼生产潜力的研究

The study on plankton and productive potential of silver Carp and Bighead in Kezisai Reservoir

克孜赛水库地处高寒地带 ,养殖水面 1 33hm2 ,多年来没有进行大规模人工养殖。1 991～ 1 999年平均鲢、鳙鱼产量仅为 52 51kg/hm2 。调查结果表明浮游植物 1 38种 ,生物量 8 72mg/L ;浮游动物 54种 ,生物量 6 74mg/L。根据浮游生物量估算鲢、鳙鱼生产潜力为 362 0

Kezisai reservoir district is situated high frigid zone,and its aquatics area is 133ha.We have not any fishes in great scale for many years.The average production of silver carp and bighead carp is 52.51kg/ha.year The research result can be summerized as follows:the species of phytoplankot is 138,biomass is 8.72mg/L;zooplankton is 54,biomass is 6.74mg/L.According to the biomass,we estimate fishery of silver carp and bighead carp is 362.09kg/ha.
