龙虾苗基地


PEIYUCHIYAOQIU

龙虾苗基地池塘以面积20-40m2、水深0.6-0.8m的水泥池为佳,土池也可,但新建水泥池要先进行去碱处理,要求靠近水源,水质较好,注、排水方便,建好防逃设施,进行池塘消毒(方法与亲虾培育相同)。消毒后施入发酵的有机肥500kg/亩,培育浮游生物供稚虾摄食。同时设置树根、竹筒等,提供龙虾幼苗辽宁福彩35选7走势图栖息、蜕壳和隐蔽场所。

(3)进水和施肥 注入新水时要过滤,以防止野杂鱼及鱼卵随水入池。同时施肥培育浮游生物,成为淡水龙虾苗辽宁福彩35选7走势图的直接天然饲料。常用有机肥料施用量为每亩75-100千克,使水色有一定的肥度。此时水位较浅,随着水的加深,要逐步增加施肥量。具体要视水色而定。
