Abstract:
The beardless barb (Cyclocheilichthys apogon) is one of the freshwater fish species native to Indonesia. Gonadosomatic index (GSI), hepatosomatic index (HSI), and sex ratio are parameters in the study of fish reproductive biology. The aim of this study was to calculate the gonadosomatic index, hepatosomatic index and sex ratio of C. apogon from the Lebak Kalong Floodplain, Ogan Komering Ilir Regency. A total of 30 C. apogon samples were used in this study. C. apogon samples were dissected to remove gonadal organs and liver organs from the abdominal cavity. The gonads and liver were weighed for the calculation of GSI and HSI, respectively. The results showed that the gonadosomatic index of female C. apogon ranged from 3.33% to 15.83%, and that of males ranged from 1.04% to 7.27%. The hepatosomatic index of female C. apogon ranged from 0.20% to 2.86%, and that of male fish ranged from 0.34% to 1.92%. The gonadosomatic index and hepatosomatic index of female C. apogon were heavier than those of males. The sex ratio was 1:1 (♂:♀). Knowledge of the gonadosomatic index, hepatosomatic index, and sex ratio can be used to determine the reproductive biology aspects of C. apogon. Further studies should be conducted to obtain more information on the reproductive aspects of C. apogon.
