暴发性鱼病,在所有的淡水鱼养殖水域,几乎都有暴发性虾病,在整个对虾生命发育期,几乎均见,但是也有例外。与青虾等混养的鱼类,却安然无恙。我县1991年至今累计养殖2000余亩,1986年至今的鱼蟹混养塘,都是例外。 实践观察,养殖对虾规格在3～4cm以下时,可谓绝对安全,暴发性虾病决不犯幼虾,我市1993年至今累计万亩对虾塘,也是例子。
Outbreaks of fish diseases, with almost any outbreak of shrimp disease in all freshwater fish farming waters, are almost always seen throughout the life of the shrimp, but there are exceptions. Mixed with freshwater shrimp and other fish, but safe and sound. Since 1991, my county has accumulated more than 2000 acres of aquaculture. Since 1986, fish and crab mixed ponds have been exceptionally excepted. Practice observation, shrimp farming specifications below 3 ~ 4cm, can be described as absolutely safe, never violent shrimp disease juvenile shrimp, the city since 1993 acres of shrimp ponds have been accumulated, is an example.
