Sustainability of Aqua-Feeds in Africa

Bio-Economic Assessment of Novel Fish Feed Formulation Software (FUTA AQUAFEEDAPP) for African Catfish Clarias gariepinus (Burchell 1822) Raised in Recirculatory Aquaculture System

Asian Journal of Fisheries and Aquatic Research, Journal Year: 2024, Volume and Issue: 26(1), P. 16 - 24

Published: Jan. 4, 2024

In the current study, data on nutritional composition and cost of conventional non-conventional fish feed ingredients were gathered, a spreadsheet was created to bank data. Four feeds formulated produced using three formulation methods namely Pearson’s Square method two other softwares, WINFEEDTM, ALLIXTM developed software (FUTA AQUAFEEDAPP); analytical tools: simple harmonic equation, linear programming stochastic techniques. The nutrient four diets evaluated in laboratory. result proximate analyses indicated that met crude protein requirements for African Catfish fingerlings, values ranged from 40.68±0.62 (Pearson square) 40.98±0.86 (ALLIX). There no significant differences moisture content, protein, fibre, lipid NFE across all treatments, however there difference ash content diets. assessment treatments significantly different, it revealed AQUAFEED had lowest investment ($1/Kg) when compared with while Pearson highest ($1.5/kg) due high inclusion fishmeal diet.

Effect of Biodigester Effluent on Carbohydrate Metabolizing Enzymes and Oxidative Stress Markers in the African Catfish (Clarias gariepinus)

Asian Journal of Research in Biochemistry, Journal Year: 2024, Volume and Issue: 14(6), P. 92 - 103

Published: Nov. 19, 2024

Background: Although the use of biodigester effluent as fish feed have been previously reported, however, its effect on metabolic activities fish, which might inform safety and administration guideline in farming is poorly understood. Aim: The aim present study was to investigate effects pig dung (PDBE) key enzymes antioxidant markers Clarias gariepinus. Methodology: Fifteen catfish (120±10 g) were purchased grouped into three. Group I (control): exposed freshwater; group two: raw PDBE; three: 1:10 dilution PDBE. After exposure, serum lactate dehydrogenase (LDH) glucose-6-phosphate (G-6-PDH) total protein concentration measured using commercially available kits while reduced glutathione peroxidase activity standard methods. Results: TP (g/dl) for control, II III 6.00±0.12; 20.0±0.10 6.86±0.02 respectively, their LDH (IU/L/min) 115.00±1.57; 422.00±5.64 105.00±5.18 respectively. G-6-PDH (U/L/min) 8.00±0.40; 32.00±0.73; 7.00±0.40 concentrations (µg/ml) 6.5±0.01; 0.5±0.01 9.83±0.12 GPx (µg/ml/min) 15±0.25; 64±1.99 10±1.33. Conclusion: Raw PDBE caused a significant alteration parameters however these alterations absent This study’s novel inclusion both diluted PDB exposures offers valuable guidelines usage aquaculture.
