Gametogénesis y desove de chione subrugosa (Wood, 1928) (Bivalvia veneridae) en el golfo de Nicoya, Costa Rica.

Abstract

Se estudió el ciclo reproductivo de una población de la almeja Chione subrugosa mediante métodos histológicos e índice de condición. El porcentaje de hembras y machos fue de 41,7: 58,3, respectivamente. No hubo evidencia de hermafroditismo; el período de mayor actividad de desove fue en junio, octubre y febrero. El índice de condición reflejó apropiadamente el desarrollo gonadal en el cap. Subrugosa. Un bajo incremento en la temperatura y una fuerte disminución en la salinidad coincidieron con los picos de desove.

The reproductive cycle of a population of the clam Chione subrugosa was studied by means of histological methods and index of condition. The percentage of females and males was 41,7: 58,3, respectively. There was no evidence of hermaphroditism; the period of greatest spawning activity was in June, October and February. The index of condition reflected appropriately gonadic development in Ch. Subrugosa. A low increment in the temperature and a strong decrease in the salinity coincided with the spaw ning peaks.
