Study on Reproductive Biology of Two SIF’s Puntius sophore and Rasbora daniconius

Abstract

The study of GSI and seasonal variation of development of ovary of any fish shows the reproductive cycle of fish and it is a very important aspect. The investigation of reproductive biology were carried out to estimate Gonadosomatic Index, Ovary Weight, Ova diameter, and Fecundity during August 2021 to March 2022. Total no. of 200 of each female individuals Puntius sophore, and Rasbora daniconius species of different size and length were dissected. The peak of average GSI value 10.17±5.33 was recorded in month of August in Puntius sophore and 2.82±2.21 in month of October in Rasbora daniconius.In  Puntius sophore maximum average fecundity was 3905.8±3668.1 recorded in month of august and in Rasbora daniconius maximum average fecundity was 1332.6±358.83 in month of September. Maximum average ova diameter of Puntius sophore and Rasbora daniconius, wasc1.99±0.27mm in month of August and 2.5±0mm in month of September respectively, Ovary weight of Puntius sophore  was recorded maximum in month of august 1.44± 0.82 and in Rasbora daniconius 0.22±0.16 in month of October.
