摘要

将鱼呼肠孤病毒(FRV)感染的草鱼饲养在人工控温的水族箱内,水温在24—30℃恒温时其死亡率无显著差异(P>0.05),而在20℃和33℃恒温时死亡率则明显降低,与24℃—30℃恒温相比死亡率有非常显著差异(P<0.01)。人工感染恒温饲养期间,死亡高峰期随水温降低而推迟,缓慢改变水温能降低死亡率,在低于20℃攻毒并维持一星期左右,即使逐步升温至30℃也不会导致感染鱼的大批死亡。

Abstract

The grass carps infected by the Fish Reovirus(FRV) were fed in constant temperature water, in which there are no notable differences of the death-rate(P>0.05)from 24℃ to 30℃. However, when the water temperature was cut down to 20℃ and gone up to 33℃the death-rate were marked reduction(P<0.01). Because of reduction of the water temperature the peak of death would be delaied. The result indicated that it did not cause a large number of grass carps to die under the condition of infection below 20℃ for a ...
