摘要
[目的]比较中国对虾与日本对虾对白斑综合征病毒的耐受力,为WSSV的病害防治提供参考。[方法]在盐度30‰和(24±2)℃下,将体长约8~9 cm的中国对虾(Fenneropenaeus chinensi)与日本对虾(Marsupenaeus japonicus)停食48 h后,投喂感染白斑综合征病毒(WSSV)的死亡对虾,观察其摄食及感染情况,比较这2种虾的对WSSV耐受力。[结果]中国对虾的平均死亡率为63.33%,发病高峰期为4~5 d,而日本对虾的平均死亡率为54.44%,发病高峰期为5~7 d,中国对虾的发病率于日本对虾,发病时间也较日本对虾早。[结论]中国对虾对WSSV的耐受能力要强于日本对虾。
Abstract
[ Objective] The aim was to compare tolerance ability of Fenneropenaeus chinensis and Marsupenaeus japonicas against WSSV, and provide reference for prevention and control of WSSV. [Method] Under salinity 30‰ and (24 ± 2)℃, body length about 8-9 cm Fennero-penaeus chinensis and Marsupenaeus japonicas were used as study object, after indigestion for 48 h, feeding dead prawn infected WSSV, the tolerance ability against WSSV was compared. [Result] The average mortality of Fenneropenaeus chinensis was 63. 33%, peak incidence was 4-5 d, the average mortality of Marsupenaeus japonicas was 54. 44%, peak incidence was 5-7 d. The mortality of Fenneropenaeus chinensis was higher than that of Marsupenaeus japonicas, the disease appearance time was also earlier than Marsupenaeus japonicas. [ Conclusion] The tolerance ability of Fenneropenaeus chinensis against WSSV is stronger than that of Marsupenaeus japonicas.
