Effect of Stocking Density and Feeding Strategy on Zootechnical Parameters and Profitability of Nile Tilapia (Oreochromis niloticus) Reared in Floating Cages in Toho-Todougba Complex Lagoon in Benin Republic

This study aimed to compare the growth performance and economic profitability of rearing Oreochromis niloticus in floating cages using three feeding strategies (5 days a week, 6 7 week) coupled with stocking densities (20, 40, 60 fish·m−3). Male monosex fish measuring 6.44 ± 0.18 cm weighing 3.42 0.7 g were used. The controls weighed every 15 from 35th day until 185 assess zootechnical parameters. BioMar feed (Efico Cromis 832F) was used during study, ration adjusted for each treatment 2 weeks. At end average weights varied 293.09 468.41 conditions 40 fish·m−3 5/7-day diet 20 7/7-day diet, respectively. yield per m2 values between 7.11 kg 23.17 kg, On other hand, better condition fish.m−3 daily feeding. These results suggest that Toho-Todougba lagoon complex, density (three times day) promotes optimization production farming.
