Japanese eel, Anguilla japonica is a commercially important species and catadromous fish that grows in fresh water, and moves to the sea to spawn. This study investigated the gametogenesis process based on artificially induced sexual maturity of A. japonica based on sexual maturity where it acclimated to the aquatic environment of the seawater. 10 female A. japonica (mean TL 70.1 ± 2.3 cm, mean BW 727 ± 74 g) were used for the inducement of sexual maturity. And specimens were treated with salmon pituitary extracts (SPE) once per week, and induced sexual maturity after 8-12 weeks, and then gametogenesis process was observed. Male A. japonica (mean TL 47.2 ± 2.5 cm, mean BW 322.8 ± 14 g) were treated with human chronic gonadotropin (HCG) every week, and allocation was induced after 6-8 weeks, and then spermatogenesis was observed.
