根据物料平衡规律，通过对鱼苗至成鱼养殖过程中增加的总氮、总磷、铜、锌含量及养殖期间投喂饵料中总氮、总磷、铜、锌含量的检测，估算获得残饵中总氮、总磷、铜、锌含量，以此来估算进入水环境中总氮、总磷、铜、锌含量。研究结果显示，合成纤维网衣网箱养殖过程中残饵中总氮、总磷、铜、锌相对投喂饵料的比值分别为12．5％、22．5％、21．3％、33．1％，金属网衣网箱养殖过程中残饵中总氮、总磷、铜、锌相对投喂饵料的比值分别为4．5％、9．7％、－11．4％、28．8％。表明金属网衣网箱养殖对水环境的影响要小于合成纤维网衣网箱养殖。

In this paper ,based on the material balance law ,through the detection of total nitrogen ,in‐crease the fry to breeding process of total phosphorus ,copper ,zinc content and during breeding ,feed of total nitrogen ,total phosphorus ,copper ,zinc content ,total nitrogen ,total phosphorus ,estimation for copper ,zinc content in order to estimate the residual bait ,into the water total nitrogen ,total phosphor‐us in the environment ,copper ,zinc content .The results display that ,net cage culture process of syn‐thetic fiber in the bait of total nitrogen ,total phosphorus ,copper ,zinc relative investment ratio of feed were 12 .5% ,22 .5% ,21 .3% ,33 .1% ,the metal net cage are respectively 4 .5% ,9 .7% ,-11 .4% ,28 . 8% ,this shows that the metal net cage culture on water environment than the synthetic fiber net cage culture .
