Se estudió el crecimiento y madurez gonadal en Crassostrea columbiensis desde febrero de 1984 hasta febrero de 1985, en Punta Morales. Puntarenas, Costa Rica. La relación peso-longitud fue P=1.04 x 10" . La ecuación de von Bertallanffy para la longitud total fue U =8.6 (1-e -0.1567(1 .(U23)). La proporción media de sexos fue 1.00 machos: 0.82 hembras. La El índice de condición promedio (IC=PCFIPVF x 100) para la población fue de 11.79 t 5.02 % y el rendimiento promedio de harina fue de 9. t 4. 11 %. Se encuentran individuos sexualmente maduros durante todo el año. La actividad de desove fue más alta en mayo. y octubre.

The von Bertallanffy equation for total lenght was U =8.6 (1-e -0.1567(1 .(U23)). The mean sex ration was 1.00 male: 0.82 females. The mean condition Index (IC=PCFIPVF x 100) for the populalion was 11.79 :t 5.02 % and lhe mean meal yield was 9.) :t 4. 11 %. Sexually mature individuals are found throughout the yeat.
