一、改白天注水為夜晚注水。在天氣正常的情況下，夜晚給漁池注水

，尤其是淩晨3時~4時或1時~2時注水，可提高池水的溶氧量，改良水質
，避免魚缺氧浮頭，對防止泛池和病害發生有明顯效果。

　　二、改吸深層水為吸淺層水。用抽水機給漁池加注新水時，通常是將抽水管插入水下1mihuogengshenchu，suoxizhudeshishencengshui。zhezhongshuiyoujizhihanlianggao

　　四、改水流直落為板落。向漁池加注新水，如果水流直接從高處落下衝水池底，由於衝入的水流、水量都較大，會將沉積在池底的飼料殘渣、paixiewujiwunidengchongfanqilai，shenzhihuizaichidichongchuyigeaotang，zaochengchigengtaxian。weifangzhizheyixianxiangfasheng，kezaishuiguanxiabuluoshuichufangzhiyigudingmuban，shizhurudexinshuiluozaimubanshang
