Deepwater snappers (Lutjanidae) support important commercial demersal fisheries in Okinawa and throughout much of the Indo-Pacific region. However, recent evidence suggests that over-exploitation has substantially reduced stock biomass throughout the

We examined the reproductive cycle, sexuality, and length at 50% maturity ( L 50 ) of the deep-sea snappers Etelis coruscans, Paracaesio caerulea, Pristipomoides filamentosus, and Pr. sieboldii from Okinawan waters based on gonadal histology. The ove

The demography and reproductive biology of three Epinephelus groupers (Serranidae), namely E. polyphekadion, E. tauvina, and E. howlandi in the Yaeyama Islands, Okinawa, were examined based on age assessment using otoliths and gonadal histology. The

Lutjanid snappers belonging to the subfamilies Apsilinae and Etelinae are commercially valuable components of tropical deep-water fisheries throughout much of the Indo-Pacific region. Based on age assessment using sagittal otoliths, the age-specific

In order to evaluate the impact of fishing on the Pacific steephead parrotfish (Chlorurus microrhinos) resource around the north of Okinawa Island, life history variables such as growth, ages of both sexual maturation and sexual transition, and the s
