Abstract

Rohtee ogilbii (Sykes 1839) is an indigenous fish from Western Ghatsof Maharashtra. The study on Fecundity and Gonadosomatic index(GSI) of Rohtee ogilbii sykes, 1839 was undertaken to investigate thereproductive potential of this fish. The mean Gonadosomatic index (%)was 8.079±0.070 with a range of 3.6-11.75. The fecundity was in rangeof 5382-23542with a mean value of 12964.2±1373.71. The correlationcoefficient for Fecundity (Y) and total body weight (X) was 0.9217.The correlation coefficient for Fecundity (Y) and total gonads weight(X) was 0.8477, the correlation coefficient for Fecundity (Y) and totalbody length(X) 0.8013, and the correlation coefficient for Gonadweight (y) and total body weight (X) was 0.9165. The regression wasline was linear when graph was plotted against the fecundity for TL,BW, GW, and GSI. The variable observed were significant at P<0.01. This study would helpin knowing the commercial potentialities of the stock as well as to impose adequateregulations for the conservation of the edible species and would also benefit the fisheryeconomics.

Keywords: Rohtee ogilbii sykes, Gonadosomatic index.
