Abstract

The study about Fecundity and Gonadosomatic index (GSI) of Osteobrama vigoressi (skyes) was undertaken to investigate the reproductive potential of this fish. The fecundity was in range of 6241 to 25262 with a mean value of 14517.4 ±42.54. The mean Gonadosomatic index (%) was 211.81 ±9.134 with a range of 4.349- 10.051. The correlation coefficient for Fecundity (Y) and total body weight (X) was 0.9629. The correlation coefficient for Fecundity (Y) and total gonads weight (X) was 0.8937, the correlation coefficient for Fecundity (Y) and total body length(X) was 0.9629, and the correlation coefficient for Gonad weight (y) and total body weight (X) was 0.9202. The regression was linear when graph was plotted against the fecundity for TL, BW, GW, and GSI. The variable observed were significant at P
