海产甲壳类血卵涡鞭虫病研究进展

血卵涡鞭虫是导致海产甲壳类疾病的主要寄生虫病原之一,国内迄今尚未见相关报道。本文结合作者近年来对海水养殖甲壳类病害的研究结果,较系统地综述了国外甲壳类寄生血卵涡鞭虫的研究进展,包括分类地位、生活史、传播途径、流行病学、组织病理以及诊断方法,并提出了相应的防治措施,旨在为中国海水养殖蟹类血卵涡鞭虫病害的研究与防治提供参考。

Progress of studies on Hematodinium sp.disease in marine Crustacean

Hematodinium is one of the most serious parasitic pathogeny which has caused the diseases in marine crustacean prevalent.Since it was first reported in the green crab along the coast of France in 1931,the parasite has been found and reported in a lot of areas including Australia,Alaska,Scotland,Canada and the eastern coast of the United States.Outbreaks of the parasites have threatened the fishery of some commercial species such as Norway lobster Nephrops norvegicus,snow crab Chionoecetes opilio,American blue crab Callinectes sapidus,Tanner crab C.bairdi,and C.opilo.As it is widespread and has caused high mortality,it has been concerned world wide,while correlating studies have not been reported in China so far.This article focuses on introducing the progresss studies on the Hematodinium disease oversea,including taxonomy morphology,life cycles,pathology,diagnostics,transmition mechanism,and puts forward some preventing and controlling techniques.The purpose is to offer some reference for future research in this field in China.
