The reproductive biology of tumid venus clamGafrarium
tumidum (Roding) was studied in detail from the
Southeast coast of India. Sample size ranged from
10.3 to 41.3mm. Sexes are separate but not di¡erentiated
externally. Annual sex ratio male:female (M:F)
deviated signi¢cantly from the 1:1 ratio with females
dominating. Based on ova diameter progression of
gonad smear and histology, four and two maturity
stages of gonads were di¡erentiated in female and
male clams, respectively. Peak spawning was observed
during November and a minor one in April.
