The mating system of the gobiid fish Trimma okinawae is one of polygynous hermaphroditism, in which the largest female of a social unit changes sex following the removal of the dominant male. Histological observations of the gonads however, revealed

Spawning behavior was observed in the red spotted grouper, Epinephelus akaara, to investigate the reason for low fertilization rates in spawning tanks. Artificial fertilization was also carried out to examine the egg quality of tank-reared fish. Grou
