    • Abstract


      The fecundity of an allochthonous feeder,Rasbora daniconius and an autochthonous feeder,Puntius amphibius in a perennial tropical pond was assessed and found to be higher in the latter. The fecundity of each of the species was correlated with parameters like standard length, weight offish, length and weight of ovary. A comparison of the regression coefficients in the relations statistically confirmed that as the length or weight of the fish and the length of the ovary increased the rate of increase in the number of eggs was greater inP. Amphibius suggesting a better assimilation of the autochthonous food byP. amphibius than of the allochthonous food byR. daniconius.
