(3)科学喂养投放泥鳅种苗5天后开始少量投饵,饲料以专用颗粒饲料为主,逐步诱食、驯化,当泥鳅对投饵形成条件反射时加大投饵量,逐步增加到泥鳅体重的3%4%。泥鳅性贪食,喜欢夜间觅食,经过驯化可改为白天摄食。有养殖户用灯光诱捕虫子让泥鳅吃。要用固定的食台,每天投喂23次。要注意残饵换的饲料。

(5)日常管理主要是加强巡塘,观察泥鳅的活动情况、水质变化情况、泥鳅吃食情况、设施运转情况等,并做好记录。高温季节保持微流水,每天注人新水,日交换量达10%以上。每天投馆时,观察有无泥鳅逃到网外,检查有无因田鼠嚼咬、操作不慎造成防逃网损坏等。经常用地笼在网外捕捞,根据捕捞量的多少,大体判断漏洞所在位置,以便人工检查、修复。

(6)病害预防泥鳅的疾病应以防为主,只要水质清新,泥辑一般没有病害。通过水质调控措施,形成良好的水域环境,泥辑就会生长旺盛,抵抗力强。要尽量做到不用药或少用药,避免有关的药物残留,实现无公害标准化泥鳅健康养殖和水产品质量安全。
