Analysis on Gonadosomatic Index and Fecundity of Terapon Puta from Nallavadu Coast Pondicherry

In the present study fecundity of Terapon puta was estimated for 47 matured females from the Bay of Bengal, Pondicherry. The fecundity (F) was found to range from 20,002 to 1,23,042 in fishes between 134-219mm Total length(TL) and 30-78 gm weight respectively. The co-efficient of correlation for F/TL (log F = 0.790+1.731 log TL), F/SL (log F = 0.799+1.773 log SL), F/TW (log F = 2.590+0.450 log TW) and F/GW (log F = 0.518 + 1.7183logGW) were obtained as0.277, 0.282, 0.248 and 0.902 respectively. The regression line for the TL, SL, TW and GW of the fishes were found to be linear when they were plotted against their fecundity on logarithmic scales. Significant (P<0.05) linear relationship was obtained for the variables standard length and fecundity. Highly significant (P<0.01) relationship was obtained between gonad weight and fecundity. Gonad weight was found to be the best indicator of the fecundity of Terapon puta.
