    • Abstract

       

      The present paper reports the fecundity(F) ofRasbora daniconius in relation to the total body length (L), total body weight (W) and gonad weight (G) of the fish. Catch data indicated a predominance of females during the months of July–August which is the breeding season of this species. The collected fish in the length range of 7·7–11·7 cm bore a linear relationship with their weights. The fecundity of the fish ranged from 580 to 11040 eggs fish−1. Fecundity exhibited a linear relationship withL, G andW. By subjecting the data to multiple regression analyses, a new and convenient method of best predictions ofF inR. daniconius in relation toL alone has been developed.
