海水贝类养殖业的迅猛发展以及养殖品种的异地养殖越来越普遍 ,导致了贝类病原性寄生虫全球范围内的广泛传播 ,而寄生虫是贝类最大的病原生物。本文比较系统地列举了导致牡蛎、贻贝、蛤类、扇贝、鲍鱼病害的寄生虫种类及体内寄生原生动物分类地位 ,为我国贝类病害的研究提供基础资料。 The rapid development of seawater shellfish farming and the growing prevalence of farmed species elsewhere have led to the widespread worldwide distribution of shellfish parasite species, the largest pathogen of shellfish. This article systematically lists the parasite species that cause oyster, mussel, clams, scallop, abalone disease and the status of parasitic protozoan in vivo, and provides the basic data for the study of shellfish diseases in China.
