220 杂志2, Vol● PreLiminary Study of the influence of Water Tamperature on the Grass Carp Hemorrhage Disease g Li-hua Wuhan Institute of Virology,, Academia Sinica, Wuhan 430071 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 24c to 30C. However, when the water temporature was cut down to 20C and gone up to 33c the death-rate were marked reduction( P< 0. 01).Because of reduction of the water temperature the peak of death woul be delaied. The result indicated that it did not cause a large number of graBs carps to die under the condition of inf ection below 20c for a week even though he water temperature was gradually gone up to 30C囊●攀囊毒 2，l●H V Jro|o| - 8 tn Pr蜊 mJnary Study ofthe Influence of W aterTemperature on the GrassCarp Hemorrhage Disease DingQiug-quan Yu Lan-fen KeLi-hua (W uhan lns：ituteo， Virology，Academia 3inlca,W uhan 430071) The grass ca~pe infected by the Fish Reovlrus(FRV )weFe fed in co．staRt tem perature water， in which there are no notable differences of the death—rate (P> O．05)from 24℃ to 30℃ ． However， when the water temperature WaBcat down to 20℃ and gone up to 33℃ the death-rate were marked reduction(P< 0，01)． Because of reduction of the water temperaturethepeakof death would be delaied． The result indicated that it did not canse a large num ber of gra~s carps to die under the condition of infeetion below 20℃ fora week evea though the water tem perature was gradually gone up to 3O℃ ． K ey w ordsl Fish reovirus Hemorrhage disease Temperature 维普资讯 http://www.cqvip.com
