1961年11月初和1962年1月,在原厦门市水产研究所的两口临海池塘里,曾两次发生非洲鲫鱼成批死亡,经检查是由于东方鱼虱(Caligus Orientalis Gussev)的大量寄生而引起的,这发病情形,不论寄主或寄生虫,在国内外都是罕见的。作者藉此机会作了防治的研究,但由于试验次数不多,以后又无再发病的机会,因此有些项目还有待进一步深入探讨。 In early November 1961 and January 1962, batch deaths of African crucian carps occurred twice in the two sea-facing ponds of the former Xiamen Institute of Fisheries, which were caused by the mass parasitization of the oriental fish louse (Caligus Orientalis Gussev) , The incidence of this disease, whether host or parasite, is rare at home and abroad. The author took this opportunity to make research on prevention and treatment. However, due to the small number of trials and the possibility of further disease later, some projects have yet to be further explored.
