Abstract

The criteria of ovarian maturity during the spawning season and maturity rates according to age are described for the female red sea bream Pagrus major collected from the Chikuzenkai between April and June, 1984. The degree of maturity of the ovary is categorized into four stages based on the maturation stage of the most advanced oocytes in the ovary, rate of atresia and occurrence of post-ovulatory follicles. The ovarian maturity rates in fish aged 2, 3, 4 and 5 years were shown to be 5.8, 46.2, 75.0 and 97.3%, respectively, assuming that yolked ovaries with low levels of atresia (<50% yolked oocytes affected) attain maturity. The fork length at which 50% of the fish attained maturity ranged from 280 to 300 mm.
