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. Not Available |
