利用工程化循环水槽养殖大口黑鲈对小型水库水质的影响分析

Analysis of the impact of using engineering circulating water tanks to cultivate largemouth bass on the water quality of small reservoirs

为了客观研究在水库中进行工程化循环水技术养殖大口黑鲈(Micropterus salmoides)对水质的影响,选择了一个农业灌溉小二型水库进行了试验。结果表明:利用工程化循环水槽养殖大口黑鲈后,在养殖区水域内,水中的氨氮、浊度比养殖前有一定的增加,但在合理范围内。养殖尾水经过处理设施处理后,各项指标都达到排放标准。

In order to objectively study the impact of engineering circulating water technology on the water quality of breeding largemouth bass in reservoirs,an agricultural irrigation small second type reservoir was selected for testing.The results showed that after using an engineered circulating water tank to cultivate largemouth bass,the ammonia nitrogen and turbidity in the water in the aquaculture area increased to a certain extent compared to before cultivation,but within a reasonable range.After being treated by treatment facilities,all indicators of the aquaculture tail water meet the discharge standards.
