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

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
