| 摘 要： | 本文通过采样监测分析了网箱养鱼对水质的影响。分析结果表明，网箱养鱼明显增加了水库水体中藻类密度ＣＯＤ、ＴＰ、ＴＮ的含量，并引起水温上升，溶解氧减少，促进水库富营养化进程，是水质恶化的重要之一。同时，残余饵料和粪便的沉积，增加了底质中的有机质ＴＰ和ＴＮ，造成水库水体的二次污染。

| Abstract: | The effect of fish flue on Water quality in Yuqiao reservoir was studied by sampling and analyses.The results showed that the fish flue,is one of the reasons resulting in increasing of the algae density,COD,total phosphate,total nitrogen,thereby the higher water temperature and lower DO of the reservoir,is an important cause of the eutrophication and water quality deterioration.At the same time, the sediment of residue pastry and the fish excrement increase the content of organic matter,total phosphate and total nitrogen within the substrate,which leads to secondary pollution of the water body of the reservoir. |
