Assessing the impact of a budget cage technology on Nile Tilapia (Oreochromis niloticus) production in the Bontanga, Golinga and Libga reservoirs in Northern Ghana, Africa

The potential of irrigation reservoirs in northern Ghana to support Nile Tilapia (Oreochromis niloticus) production 1 m3 budget cages was assessed over six-months three (Bontanga, Golinga and Libga). Fingerlings with a mean weight 17.0 ± 5.0 g were randomly stocked at 50, 100, 150, 200 250 fish per cage duplicate fed commercial tilapia feed (Raanan, 30% protein level) 3 5% body weight. results indicated that the lower densities (50 100 m-3) had higher specific growth rate (SGR) compared (150-250 m-3). gross yield (7.5–23.1 kg cage-1) differed increasing density on all reservoirs. Consumers Tamale Metropolis preferred small sized tilapias (5-6 kg-1) willing pay US$ 1.40-2.34 kg-1 fish, while restaurants 2-3 3.27- 3.51 kg-1. m-3 stocking most profitable is recommended for culture Ghana.
