Gonadal development of the hairy mussel, Trichomya hirsute (Mollusca: Bivalvia) from Lake Macquarie, New South Wales

摘要

A histological study of reproductive periodicity in the hairy mussel,Trichomya hirsuta, from Lake Macquarie, New South Wales, found partial spawning throughout the year in males. Few female mussels were spawning but three peaks in gonadal development and regression suggest corresponding female activity. The gonads of both sexes underwent development throughout the year.
