Abstract
In this study, we examined the maturation and spawning of yellowback seabream Dentex tumifrons using samples collected by monthly bottom trawling in Korean coastal waters from January to December 2018. We analyzed monthly changes in gonadosomatic index (GSI), maturity stage, histology, fecundity, and total length at group maturity. Spawning occurred in May and October. Fecundity varied with total length as F=1.3754TL3.2664, with a range of 1,220 to 155,625 eggs per female. At group maturity, 50%, 75%, and 97.5% estimates of female total length were 18.4, 20.5, and 25.3 cm, respectively.
