(3)科學喂養投放泥鰍種苗5天后開始少量投餌,飼料以專用顆粒飼料為主,逐步誘食、馴化,當泥鰍對投餌形成條件反射時加大投餌量,逐步增加到泥鰍體重的3%?4%。泥鰍性貪食,喜歡夜間覓食,經過馴化可改為白天攝食。有養殖戶用燈光誘捕蟲子讓泥鰍吃。要用固定的食臺,每天投喂2?3次。要注意殘餌換的飼料。

(5)日常管理主要是加強巡塘,觀察泥鰍的活動情況、水質變化情況、泥鰍吃食情況、設施運轉情況等,并做好記錄。高溫季節保持微流水,每天注人新水,日交換量達10%以上。每天投館時,觀察有無泥鰍逃到網外,檢查有無因田鼠嚼咬、操作不慎造成防逃網損壞等。經常用地籠在網外捕撈,根據捕撈量的多少,大體判斷漏洞所在位置,以便人工檢查、修復。

(6)病害預防泥鰍的疾病應以防為主,只要水質清新,泥輯一般沒有病害。通過水質調控措施,形成良好的水域環境,泥輯就會生長旺盛,抵抗力強。要盡量做到不用藥或少用藥,避免有關的藥物殘留,實現無公害標準化泥鰍健康養殖和水產品質量安全。
