| Abstract | ||||
| The present study provides preliminary analysis on the feeding and reproductive characteristics of Onychostoma lepturum. The gastrointestinal structure of O. lepturum is long gut with an average RLG value ranges between 4.94 – 5.05, which is suitable for the herbi-omnivore fish. The food composition of O. lepturum includes 4 main types, algae, insects, crustaceans and organic detritus. The difference in the reproductive organs of males and females are clearly visible. Histological specimens of the gonads can clearly and accurately distinguish the developmental stages of the gonads. The maximum GSI values were recorded in April and the GSI values were the lowest in October for males and females respectively. | ||||
