【 摘 要 】

In this study, human chorionic gonadotrophin (HCG) hormone of 1, 3, 5 and 7-days interval injection was done to investigate the morphological and growth changes in relation to maturation on male Japanese eel, Anguilla japonica in the tropical region within two months. No significant difference was found in all growth parameters. However, noticeable growth and morphological changes were only seen in the 5-day interval of hormone injection compared to other treatment. Hence, this study suggests that Japanese eel of 5-days injection interval has high possibility to achieve sexual maturation by taking growth and morphological changes into consideration.
