Oogenesis, hepatosomatic and gonadosomatic indexes, and sex ratio in rosy barb (Puntius conchonius)

Seven stages of oogenesis were identified in the rosy barb (Puntius conchonius). Oogonia were present throughout the reproductive cycle. A group-synchronous ovary with a possible asynchronous ovarian development was observed. The most important event observed during the developmental stages of oogenesis was the observation of the crystalline yolk (at the maturation stage). Maturation of females was observed at 112 days post hatch. Mean hepatosomatic index (HSI) and gonadosomatic index (GSI) increased with increasing mean body weights and lengths during gametogenesis in females. The relationship was statistically significant (p< 0.05). The sex ratio observed in 300 fish was 210:80 (female:male) and the difference was statististically significant (p<0.05).
