通过测试鲢、鳙不同生长阶段的氮、磷含量以及粪物质的氮、磷含量 ,回归分析体重与氮、磷含量的关系。比较研究了鲢、鳙不同生长阶段的排泄物中氮、磷含量。养殖大个体鲢鳙可降低水体中磷含量
Through the test of nitrogen and phosphorus content in different growth stages of silver carp and bighead carp, and nitrogen and phosphorus content in the manure, the relationship between body weight and nitrogen and phosphorus content was analyzed by regression analysis. The contents of nitrogen and phosphorus in the excrement in different growth stages of silver carp and bighead carp were compared. Breeding large individual silver carp and bighead carp can reduce the phosphorus content in water
