摘要
对辽宁省大伙房水库（1980－1987）和柴河水库（1981－1987）的水文、理化和生物数据，与这两座水库同时间的不投饵网箱养殖的鲢、鳙鱼种的生长和产量进行了回归分析。结果表明，7－8月的入库水量和出库水量、9月与6月间的水位差等参数同鲢、鳙均重及产量相关显著，用它们来估测大水体鲢、鳙的生长与产量是可行的。
This paper deals with the regression analysis of mean body weight and yield ofsilver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis)in cage culture without feeding, against the environmental variables, such as hydrographic,physical, chemical and biological indexes in Dahuofang Reservoir during 1980-1987 and Chaihe Reservoir during 1981-1987. The results show that the inflow,outflow from July to Aug., and the difference of water levels between Sept.and June are significantly correlated to the mean body weight and the yield of the fishes and so could be used to estimate the growth and production of the fishes in reservoirs.
