研究了山东省１９９３─１９９４年对虾暴发性流行病的群体病症及其发展，分析了该病的地区、时间、种间分布及个体差异。结果表明：典型的虾池发病历时一周，死亡率达９０％以上；凡虾池密集（＞７０公顷／公里海岸线）、放苗量大（４５—６０万／公顷）、投入高（４５，０００—７５，０００元／公顷）的地区发病早、损失大。发病时间主要在６—７月。１９９３年病程短而急，形成一个发病高峰，近似流行病学的偏态分布（对数常态分布）；１９９４年病程长而缓，部分地区形成两个高峰。根据流行病学原理推算了１９９３年青岛流亭对虾暴发性流行病的平均潜伏期（６．０２天）和暴露日期。依据１０７个样品的切片分析，证实对虾暴发性流行病的病原为皮下及造血组织坏死病毒（Ｈｙｐｏｄｅｒｍａｌａｎｄｈｅｍａｔｏｐｏｉｅｔｉｃｎｅｃｒｏｓｉｓｂａｃｕｌｏｖｉｒｕｓ，ＨＨＮＢＶ）。还讨论了流行病发生与环境因子，如温度、溶氧、ｐＨ、浮游生物、放苗密度以及投饵等之间的关系。 The population disease and its development of shrimp outbreak epidemics in Shandong Province from 1993 to 1994 were studied. The regional, temporal, interspecific distribution and individual differences of the disease were analyzed. The results showed that the typical shrimp ponds lasted over one week and the mortality rate was over 90%. Where shrimp ponds were intensive (> 70 ha / km coastline), Fangmiao large (45-60k ha / ha) -75,000 yuan / ha) areas early onset, loss of large. The onset time is mainly in June-July. Short duration and acute illness in 1993, the formation of a peak incidence, approximate epidemiological skewed distribution (lognormal distribution); 1994 long and slow course, in some areas the formation of two peaks. According to the epidemiological principle, the average incubation period (6.02 days) and exposure date of the epidemic epidemic of Limbus shrimp in 1993 were estimated. Based on the analysis of 107 samples, the pathogen of shrimp epidemic outbreak was confirmed to be Hypoderma and hematopoietic necrosis virus (HHNBV). The relationship between the occurrence of epidemics and environmental factors such as temperature, dissolved oxygen, pH, plankton, density of amurense and feeding is also discussed.
