抄録

The reproductive biology of the wrasse, Cirrhilabrus temminckii, was studied at one of the Izu Islands, Miyake-jima, Japan during August and September, 1979. Most males at the study site were territorial while females occurred in“herds.” Individual females migrated between male territories, indicating a promiscuous, but not necessarily random, mating system. The reproductive season at Miyake-jima was estimated to occur between May and September. Reproductive activity occurred in the afternoon and three pre-spawning actions were observed: flashing, rushing and looping.Only pair spawning was observed. Spawning tended to occur earlier as the time of sunset advanced. A relationship between timing of spawning and light intensity is suggested. Individual males were observed to spawn from 1 to 26 times per day. Interference spawning by a territorial, terminal-phase male is described.Initial-phase males are not believed to occur in this population. Male territoriality appeared to be based on the defense of territories for spawningassociated activities.
