摘要
Growth and sexual maturity in Saccostrea palmula were studied between May 1998 and May 1999, in Morales estuary, Punta Morales, Puntarenas, Costa Rica (n = 540 individuals according to sample size equation). The weight-length relationship for the population was Pt = 2.13 x 10(-2) Lt(1.6602) and von Bertalanffy growth function was Lt = 68.2 (1-e(-0.1577)). The mean sex ratio was 1,00 male: 0.92 females with sexually mature individuals found throughout the year, Spawning activity was highest between November and January. The mean condition index (IC=PCF/PV x 100) for the population was 121.53 +/- 2.24 and the mean meat yield was 10.32 = 1.64%.
