水泥池:新建水泥池在放养蝌蚪前应浸泡7~10天,用清 水洗刷干净,然后用消毒剂或漂白粉消毒,在阳光下曝晒2~ 3 天后再放入新水养殖蝌蚪。

用生石灰清池后7 ~10天,漂白粉清池后4 ~5 天,可向 池中进水60厘米左右。因为孵化出的蝌蚪在卵黄囊消失后, 开始摄食浮游植物,所以在蝌蚪下池前的四五天,蝌蚪池还要 施肥,以培肥水质。每 667平方米水面可施放牛粪300千克, 或施放鸡粪150千克,但首先必须经过发酵。施牛粪,培肥的 水质比较稳定,使用方法一般用堆肥法即可,即把肥料堆放在 向阳的两个角上,池水刚刚把肥料淹没, 过一星期左右, 将肥 料翻动一次,促使其发酵分解。施用鸡粪,尤其是没有发酵过 的,用来培肥水质很不稳定,特别是在春天,施放后很长时间 水不肥,待水温突然升高时,水质会一下变得过肥,甚至变老, 因此,施放的鸡粪最好要经过发酵。方法是把鸡粪装成袋,每 袋 15千克左右,然后放在池边水中,袋与袋之间保持一定距 离, 当看到水质变肥时,可将袋提出来, 这样才不至于造成水 质过肥。
