摘要/Abstract

摘要： 绢丝丽蚌钩介幼虫在雌蚌外鳃中发育成熟后于冬季排放到体外,而后寄生到宿主鱼的鳃丝进行变态发育,寄生期历时近4个月.寄生后3d,内、外足丝消失;35d后,肉足形成;90d后,肠、闭壳肌、肾脏和鳃原基等生成;壳面加厚且外凸.次年春季,钩介幼虫变态发育成大小为253.37×273.26×179.96μm的稚蚌,脱离鱼鳃营独立生活.

Abstract: The glochidia of Lamprotula fibrosa develop to maturity in the outer gill of female and are expelled to the outside in winter, and then,the mature glochidia are parasitized to the gill of fish host and start the parasitic metamorphosis development.The parasitic period lasts about 4 months.The inner and outer byssuses disappear after parasitizing for 3 days.The foots develop after 35 days.The intestine,adductor muscle,nephridium and gill anlage develop after 90 days.The shells become thick and protrusive.The glochidia become larvae with a size of 253.37×273.26×179.96μm in the next spring,then leave the gill of fish host,and start their independent life.

Key words: Lamprotula fibrosa, Glochidia, Parasitic metamorphosis development, Larva
