The maturation and spawning of white crocker Pennahia argentatus were investigated using samples collected in the
Southern Sea of Korea from January to December 2018. We analysed monthly changes in maturity stage, gonadosomatic
index (GSI), total length (TL) at 50% group maturity. The spawning period was May to July. Fecundity
varied between 71,627 and 888,041 eggs. The relationship between the fecundity and TL of the fish was expressd in
the fecundity equation as F=0.2198TL4.2784 (r2=0.8423). The percentage of sexually mature females estimated from a
logistic function was over 50% for the size group 19.33 cm (total length, TL).
