本文根据浮游植物生产量求得对鲢、鳙的供饵能力,并通过浮游植物对鲢、鳙转化效率的计算,估算出武昌东湖鲢、鳙的生产潜力,进而求得武昌东湖鲢、鳙的合理投放量。作者求得东湖浮游植物全年对鲢、鳙的供饵能力是61,153吨(鲜重);由此估算出东湖鲢、鳙的生产潜力是789公斤/公顷以上,每年鱼种(四寸以上)的合理投放量,鲢是 209万尾,鳙是 110万尾。
Based on the phytoplankton production, we calculated the yield potential of silver carp and bighead carp, and calculated the production potential of silver carp and bighead carp by phytoplankton, and then obtained the production potential of silver carp and bighead carp in Wuchang East Lake, Reasonable volume. The authors estimated that annual phytoplankton production in Donghu Lake is 61,153 tons (fresh weight) for silver carp and bighead carp, and the production potential of silver carp and bighead carp in the East Lake is estimated to be 789 kg / ha. Annual fish species (more than 4 inches) A reasonable amount of investment, silver carp is 2090000, 鳙 is 1.1 million.
