Abstract:
The present investigation was carried out to study Gonadosomatic index and fecundity of Schizothorax niger in Dal Lake, Kashmir. A total of 360 samples of S. niger were collected from Dal Lake from August 2018 to July 2019. The mean values of GSI in case of males was found lowest during July (0.53) and highest mean value of GSI was found during march (11.08), while in case of females lowest mean value of GSI was found during July (1.36) and highest mean value was found during March (15.13). Based on GSI values, peak spawning was observed in March in S. niger. Absolute fecundity of S. niger varied from 2700 to 16,758 and relative fecundity varied from 28 to 89 ova per gram of body weight. In the present study, positive correlations were observed between fecundity and length and weight measurements of the fish as well as the ovaries in S. niger. High positive correlation was found between fecundity and ovary weight in S. niger with R² = 0.979.
