Abstract

The annual gonad condition of Anadara antiquata was determined histologically in biweekly samples collected over a two-year period from Calatagan, Batangas, Philippines. Examination of gonad sections showed that gametogenic activity and spawning occur continuously throughout the year, with peak spawning from July to September. Fluctuations of the gonad index suggest that the duration of the gametogenic cycle is 1-2 months.
