养殖中国对虾暴发性流行病病虾现场快速诊断方法研究

A Simple and Rapid Diagnosis of Explosive Epidemic Disease for the Cultured Shrimp (Penaeus chinensis)

通过人工投喂感染试验，观察了中国对虾感染暴发性流行病病原后出现的特殊外观病症，即与健康是截然不同的空胃和拒食。在现场利用这种外观症状作排外诊断和鉴别诊断，可以简便、快速地判断出池虾群体中有无病虾，同时根据统计发病虾的概率，也可以了解群体的发病进程。

Based on the infectious trials, the earlier cardinal symptoms (a characteristic feature of empty stomach and rejection of feeding)of the shrimp (P.chinensis)suffered from foe explosive epidemie disease were observed by naked eye. By using the diagnosid by exclusion and differential diagnosis of these symptoms,a few of diseased shrimps can be rapidly separated from the healthy ones,and the probability of which can also be calculated in the growout ponds.
