Ciclo reproductivo y fecundidad parcial de Isacia conceptionis (Perciformes, Haemulidae) en La Herradura, Coquimbo, Chile

This study analyses reproductive aspects of the fish Isacia conceptionis based on 280 females collected at La Herradura Bay, northern Chile, between April 1995 and March 1996, using histological analysis of the ovaries, measurement of gonadosomatic and gonadic indices and the batch fecundity. Five m...
