| الوصف: | Yellowstripe goatfish, Mulloidichthys flavolineatus, is a widely distributed commercial fish in the Indo-Pacific. However, there have been few comprehensive studies on its life history, which is important for resource management. In this study, we examined age, growth, sexual maturity, and spawning season of M. flavolineatus near Okinawa Island, southern Japan, based on sectioned otolith and gonadal histology. These fish have short life spans, with a maximum age of 5 + years and reach maturation within the first year of life. Monthly changes in the appearance of an opaque edge indicate annual production of otolith bands. This fish shows sexual size dimorphism due to the faster growth of females compared to males. The von Bertalanffy growth functions were Lt = 31.5{1-exp[-0.61(t + 0.44)]} for females and Lt = 24.8{1-exp[-0.75(t + 0.48)]} for males. Observed fork lengths at 50% maturity were 17.0 cm for female and 14.5 cm for male. The spawning season occurs from May to September, and the peak is from May to July. Histological observations and fish market surveys indicate that the peak spawning and catching seasons overlap substantially. The development pattern of oocytes in the Okinawan fish showed group synchronous spawning, which indicates a different spawning strategy than that of this species with genetic continuity in other regions. |
