2.苗种质量。要选择体质健壮、流动力强、体表光滑、无病无伤的泥鳅苗种。

3.苗种消毒。苗种放养前,要用20~30克/升的食盐水浸浴5~10分钟,以杀灭体表病原体。

4.放养密度。在泥鳅养殖期间,如放养密度低,则造成水资源铺张;放养密渡过高,又轻易导致泥鳅患病。一般放养体长3~4厘米的夏花100~150尾/平方米,体长在5厘米以上的苗种可放养50~80尾/平方米,前提好的情况下可适当增加放养量,否则要适当减少放养量。

5.饲料治理。泥鳅是一种杂食性的淡水鱼类,尤其喜食水蚤、丝蚯蚓及其它浮游生物,但动物性饲料一般不宜单独投喂,否则轻易造成泥鳅贪食,消化不良,肠呼吸不正常,“胀气”而亡。对腐臭变质的饲料不能投喂,否则泥鳅易患肠炎等疾病。
