Aspects of reproduction of the blue mussel mytilus edulis pelecypoda mytilidae in long island sound usa


, : Aspects of reproduction of the blue mussel mytilus edulis pelecypoda mytilidae in long island sound usa. Fishery Bulletin (Washington D C) 81(4): 733-740

A population of M. edulis in Long Island Sound, Fairfield, Connecticut, was studied for 2 yr to determine the sequence of gametogenic development of gonadal tissue and the frequency and duration of spawning under natural conditions. This population spawned annually in May-June. Dribble spawning occurred during the winter months of 1982. Sexes were distinguishable in all size classes studied, except those individuals in an inactive condition (stage 0). A low incidence of simultaneous hermaphroditism suggests that M. edulis is a stable gonochoric species. There was no evidence of protandry. Sex ratios of M. edulis 26.0-72.1 mm shell length did not differ significantly from 1:1. Photomicrographs of the gametogenic cycles of both male and female mussels are included.
