Histological Study on the Development of Gonad of Isognomon ephippium
摘要
Abstract
Isognomon ephippium,withspecial lurid pearllayer,is a potentialaquaculture breed to cultivate specialcolor specialpearl. The historical identification of gonad development and reproductive cycle was important for breeding and pearl cultivation inI. ephippium. The development of gonad inI. ephippium was analyzed by histological sections technology. The data indicated that the development of both male and female gonads ofI. ephippium was devided into the proliferation stage,increasing stage, maturation stage,breeding stage and suspensive stage,with specific characteristics of gonads and germ cells. In the proliferation stage,oogonium and spermatogonium were produced in new follicles.In increasing stage,the area of the gonads,the number of follicles and germ cells were increased obviously. Massive oocytes and spermatocytes existed in follicles. In maturation stage,the follicles were filled with oocytes,which had bright germinal vesicle,clear nucleolus,and sperms with red tails. In breeding stage,mature germ cells were released from damaged follicles. In suspensive stage,follicles were shrinked and no germ cells were found. The reproductive cycle ofI. ephippium was one year,including proliferation stage from May to June,increasing stage from July to August,maturation stage from August to September,breeding stage from September to October,suspensive stage from October to November. Most gonads did not grow from December to next April.关键词
