Contrast of Water Quality in Different Culture Ponds of Dongting Lake Region
摘要
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 .关键词
