The reproductive cycle, egg diameter compositions, spawning season and first sexual maturity of the pomfret, Pampus echinogaster, were investigated by histological analyses and morphometric data. The reproductive cycle of this species can be divided into six successive stages in females: early developing stage (February to March), late developing stage (March to April), mature stage (April to June), ripe and spawning stage (June to early August), recovery and resting stage (August to October), and immature stage (October to February). Males can be divided into five successive stages: developing stage (February to April), mature stage (March to June), ripe and spent stage (June to August), recovery and resting stage (August to October), and immature stage (October to February). According to the frequency distributions of egg diameters in a spawning season, P. echinogaster is a polycyclic species that spawns two times or more during the spawning period. The percentages of P. echinogaster that had reached first sexual maturity over 50% in males from 12.1 to 15.0 cm in body lengths, while in females, those from 15.1 to 18.0 cm in body lengths reached over 50%. And both sexes were 100% for fishes over 21.1 cm in body length.
