本文报道了养虾过程中,虾池水和底泥泥浆中细菌数量变化规律以及“红腿病”虾心肌带菌率。结果表明;虾池水细菌数量受季节影响,底泥中细菌数量不受季节影响而一直上升;同期底泥细菌数量均高于池水细菌数量。病虾心脏带菌率随养虾时间延长而上升。并与底泥细菌数量增加趋势相同,与池水细菌数量关系不明显。说明底泥细菌含量过高是引起对虾红腿病的主要原因之一。
In this paper, the variation of bacteria in shrimp pond water and sediment slurry and the incidence of “red-legged disease” shrimp myocardium in shrimp culture were reported. The results showed that the number of bacteria in the shrimp ponds was affected by the seasons, and the number of bacteria in the sediment was not affected by the seasons. The number of bacteria was higher than the number of bacteria in the pond water at the same period. The incidence of diseased shrimp heart rate increased with shrimp time. And with the increase of sediment bacteria the same trend, and the number of bacteria in the pool water is not obvious. Description of sediment bacterial content is too high is caused by shrimp red leg disease one of the main reasons.
