The reproductive biology of the mangrove clam Polymesoda erosa (Solander 1768) in Lianzhou Bay
摘要
Abstract
The gonadal development, reproductive cycle, and embryonic development of Polymesoda erosa sampled from Lianzhou Bay of Beihai, Guangxi from August 2011 to July 2012 were studied. The results showed that P. erosa was dioecious and the sexes can be differentiated by the colors of ripe gonads. The clam had one productive cycle a year. The gametogenesis of P. erosa can be divided into five stages, including early active stage, late active stage, ripe stage, partially spawned stage and spent stage. Gametogenic development was synchronous between the sexes. P. erosa reproduced from June to November, and reached reproductive peaks in July and October. The Con-dition index peaked in May at 5.19% and footed in February at 1.98%. The clam exhibited no brooding of larvae and released demersal eggs with a thick glue egg membrane. Fertilized eggs reached D larvae stage around twenty-seven hours at 26℃.关键词
