摘要:
为了解河蟹池塘养殖场水体及底泥中氮、磷动态变化规律,减少对周边水域的污染,选取太湖流域典型河蟹养殖场,监测水体及底泥中氮、磷周年动态变化. 结果表明,河蟹养殖场水体氮、磷浓度在第5次蜕壳期(7—8月)最低,育肥期(9—10月)最高,底泥中氮、磷负荷育肥期最高,捕捞季最低. 育肥期养殖塘水体TN、TP和NH3-N劣于国家地表水环境质量标准V类水标准,捕捞季TN和TP超出太湖流域池塘养殖水排放标准一级标准. 建议合理设置蟹苗投放量,加强日常管理,重点关注育肥期池塘水质的控制.
Abstract:
In order to understand the dynamic changes of nitrogen and phosphorus in the water body and sediments of crab farming ponds and reduce the pollution to the surrounding waters,a typical crab farm in Taihu Lake Basin was selected to monitor these parameters. The results showed that the concentration of nitrogen and phosphorus was the lowest during the fifth shelling period(July-August)and the highest during the fattening period(September-October). The load of nitrogen and phosphorus in sediments was the highest in the fattening period and the lowest in the fishing season. The TN,TP and NH3-N concentrations of pond waters during the fattening period were inferior to the Class V water standards of the National Surface Water Environmental Quality Standard,and the TN and TP during the fishing season exceeded the first-level standard of the Discharge Requirements of Pond Aquaculture Water in Taihu Lake Basin. It is recommended to set the reasonable amount of crab seedlings,and strengthen the daily management,and pay attention to the control of pond water quality during the fattening period.
