海水鱼血居科Sanguinicolidae吸虫病的研究现状

海水血居吸虫(Sanguinicolidae)病是严重影响一些重要商业鱼(金枪鱼、琥珀鱼等)养殖发展的一大疾病。该病具有一年一次流行高峰的流行特点,其流行要求一定的水温范围。血居吸虫感染养殖鱼,常常引起高感染率和高死亡率。在同一海区,原来寄生于野生鱼体内的血居吸虫可通过一定途径感染养殖鱼并造成流行,引起重大的经济损失。根据近几十年国内外对该病的研究,对海水鱼血居科吸虫病的危害现状、流行病学规律以及综合防治等方面进行了综合评述,总结了血居科吸虫病的研究现状及研究中亟待解决的问题,为进一步开展对该病的综合防治研究提供科学理论依据。

The status of the research on disease of Sanguinicolidae in marine fishes

The disease of sanguinicolid trematodes(Sanguinicolidae)has a serious impact on the aquaculture of some commercial important fishes(tuna,amberjack,etc).It occurs once a year,and its prevalence needs a certain water temperature range.The rates of infection and death are usually high in cultured fishes.Sanguinicolids from the wild fishes can infect the cultured ones in the same sea area,leading to heavy economic losses.Here we reviewed the recent studies on this disease,including the hazards,epidemic features and integrated control methods used recently.At the same time we summarized the problems need to be solved urgently.It can be a reference for further study on the control of the disease.
