Effects of replacing fish by-product meal with poultry by-product meal on growth performance of African catfish (Clarias gariepinus, Burchell 1822) in Recirculation Aquaculture System (RAS)


Author(s): Elsadig Arbab Hagar and Ahmed Mohammed Musa

Abstract: The study was conducted in recirculation aquaculture system in 20 July 2017. RAS is the moderate system in aquaculture technology. The experiment designed by five treatments with three replicates, 75 Clarias gariepinus (10.05gm) in 150 L/tank. Five experimental diets were formulated (37.36 % C.P.) depended on replacements of fish by-product meal with poultry by-product meal as T1 (0.0) %, T2 (25%), T3 (50%), T4 (75%) and T5 (100%). Results showed fish fed diet T1 attained highest weight (371.18± 7.30), weight gain (361.11± 7.21) and RGR (97.28± 0.03%). Next in performance was diet T5; T3 and T2 respectively. While the lowest growth were attained by fish fed T4 (p<0.05). The best FCR was in T1 (p<0.05), while diets T4 showed the poorest performance. The survival rate showed no significant different (p>0.05). Body composition resulted highly significant differences (p<0.05). Water quality resulted no significant (p>0.05) between T1 and T5. It is concluded that complete replacement of fish by-product meal with poultry by-product meal in diets of Clarias gariepinus it's affectless.
