牛蛙蝌蚪,牛蛙苗早期发现气泡病应该采取什么措施,怎么做才能预防呢?

时间:2019-6-5

现阶段是牛蛙蝌蚪养殖阶段,放苗时间集中在清明节前后,单个池塘放苗密度约为20-25万尾,一天投喂2餐,6-7月开始变态为小蛙。变态成活率和前期的水质管理以及病害发生率密切相关,其中气泡病是影响前期成活率的主要疾病,容易引起蝌蚪出现大面积跳水、浮头、活力差,不下沉,同时会继发细菌感染,造成红肚子、大肚子等症状。本文介绍气泡病发生原因和预防措施以供您参考。

4、pH值升高  本地区蝌蚪池塘普遍pH值较低,氨氮高,但是一般不出现亚硝酸盐,当pH值升高,氨氮转变为氨气和氮气过程容易产生氮气气泡病或者氨中毒。
