Effects of stocking density on growth and production performance of Monosex male tilapia (Oreochromis niloticus) in earthen ponds


Author(s): Md. Moshiur Rahman, Parvez Chowdhury, Md. Shahidul Islam

Abstract: To assess the effects of stocking density on growth and production of monosex male tilapia (Oreochromis niloticus) in ponds, an experiment was carried out during the period of two months from March to May 2015. Three stocking densities used were 50, 100 and 150 fish/decimal and designated as T1, T2 and T3, respectively with three replications. Fish were fed with commercial pelleted feed containing 30% crude protein. After two months, the growth performance was evaluated by comparing mean final body weight and specific growth rate (SGR). The result of the present study showed that, the fish in T1 stocked at the rate of 50 fish/decimal resulted the best individual weight gain (35.97g) followed by T2 (34.27g) and T3 (32.13g), respectively. The SGR ranged between 8.77 and 8.95%. There was no significant variation (P<0.01) among the survival rate (%) which ranged from 74.56 to 78%. The production was 1.40, 2.58 and 3.59kg/decimal in T1, T2 and T3, respectively. But the highest production of 3.59kg/decimal was obtained in T3 with stocking of 150 fish /decimal due to higher stocking density. Although the highest production was obtained in T3 but individually growth performance of monosex male tilapia was higher in T1. Based on the result of present experiment, farmers could be suggested to rear tilapia (O. niloticus) at lower stocking density (50 fish/dec) to get higher growth and survival in a short period of time
