| 摘 要： | 目的]对比洞庭湖区不同养殖池塘的水质状况。方法]以珍珠养殖池塘、四大家鱼苗种养殖池塘、四大家鱼成鱼养殖池塘、大水面、藕池、浮萍池等养殖池塘和进水沟为研究对象,分别测定各水体中COD、氨氮、亚硝酸氮、总氮、总磷、可溶性磷的含量,并进行对比分析。结果]藕池中的COD含量显著高于其他水体(P0.05),苗种池和进水沟的COD含量差异不显著(P0.05),7大水体中珍珠养殖池的COD最低;苗种池中的氨氮含量显著高于其他水体(P0.05),大水面、进水沟和珍珠养殖池的氨氮含量差异不显著(P0.05),其中以珍珠养殖池的氨氮含量最低。成鱼池中的亚硝酸盐氮含量显著高于其他水体(P0.05),珍珠养殖池和浮萍池中的氨氮含量差异不显著(P0.05),其中珍珠养殖池的亚硝酸盐氮含量最低。大水面中的总氮含量显著高于其他水体(P0.05),进水沟和浮萍池中的总氮含量差异不显著(P0.05),其中珍珠养殖池的总氮含量最低。大水面中的总磷含量与进水沟差异不显著(P0.05),但显著高于其他水体(P0.05),浮萍池与藕池中的总磷含量差异不显著(P0.05),其中珍珠养殖池的总磷含量最低。大水面中的可溶性磷含量显著高于其他水体(P0.05),进水沟和成鱼池的可溶性磷含量差异不显著(P0.05),浮萍池和苗种池的可溶性磷含量差异不显著(P0.05),其中珍珠养殖池的可溶性磷含量最低。结论]该研究结果可为养殖池塘水质的调控与管理以及合理、可持续的渔业开发提供参考依据。

Contrast of Water Quality in Different Culture Ponds of Dongting Lake Region |
| |
| Abstract: | Objective] To contrast water quality situation in different culture ponds of Dongting Lake.Method] Taking pearl aquaculture pond, four main Chinese carps fry pond,four main Chinese carps breeding pond, large water surface, lotus pool, duckweed pond and water inlet ditch as the research objects, the concentrations of COD, ammonia nitrogen, nitrite nitrogen, total nitrogen, total phosphorus and soluble phosphorus in water body were measured, and the contrast analysis was conducted.Result] The COD content in lotus pool was significantly higher than that in other waters (P<0.05), the difference in fry pond and water inlet ditch was not significant (P>0.05), pearl pond had the lowest COD in the 7 waters.The ammonia nitrogen content in fry pond was significantly higher than that in other waters (P<0.05), the difference in large wa-ter surface, water inlet ditch and pearl pond was not significant (P>0.05), and pearl pond had the lowest ammonia nitrogen content in the 7 waters.The nitrite nitrogen content in breeding pond was significantly higher than that in other waters (P<0.05), the difference in pearl pond and duckweed pool was not significant (P>0.05), and pearl pond had the lowest nitrite nitrogen in the 7 waters.The total nitrogen content in large water surface was significantly higher than that in other waters (P<0.05), the difference in water inlet ditch and duckweed pool was not significant (P>0.05), and pearl pond had the lowest total nitrogen content in the 7 waters.The total phosphorus content in large water surface was significantly higher than that in other waters (P<0.05), but the difference in it and water inlet ditch was not significant (P>0.05), the difference in duckweed pool and lotus pool was not significant (P>0.05), pearl pond had the lowest total phosphorus in the 7 waters.The solu-ble phosphorus content in large water surface was significantly higher than that in other waters (P<0.05), the difference in water inlet ditch and breeding pond was not significant (P>0.05), the difference in duckweed pond and fry pond was not significant (P>0.05), pearl pond had the lowest soluble phosphorus in the 7 waters.Conclusion] The research results could provide reference basis for regulation and management of wa-ter quality in culture pond and reasonable and sustainable fishery development . |
