Estimation of the Fecundity of Threatened Pethia ticto

In order to estimate fecundity of threatened small indigenous fish species, tit punti (Pethia ticto), an investigation was done at the Field Laboratory Complex, Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh during June to August, 2017. The mean total lengths were 5.39 ±0.58, 5.20 ± 0.43, 5.79 ± 0.97 cm and mean ovary weights were 0.45 ± 0.20, 0.38 ± 0.15, 0.53 ± 0.26 g for the month of June, July and August, respectively. The fecundity of P. ticto for the month of June was estimated to be 1120-13892 with a mean of 5319.62 ± 3169.16, for the month of July it was 1071-12325 with a mean of 5407.68 ± 3186.82 and for the month of August it was 2268-14328 with a mean of 5919.92 ± 3436.29. The gonadosomatic index (GSI) were 16.62 ± 3.35, 19.01± 4.55 and 14.75± 2.53 for the month of June, July and August, respectively. The highest GSI was observed in July (25.77) and the lowest was 10.53 in June. Information of fecundity and GSI of P. ticto will be helpful for artificial propagation, conservation, and management of this fish species.
