The main objective of this study was to assess the impact of local zeolite on the amino acid and fatty acid profiles in the meat of African catfish (Clarias gariepinus). The fish were divided into three groups: the first (control) group was fed a basic diet, the second (experimental) group received the same diet with 3% zeolite, and the third (experimental) group received the same diet with 5% zeolite. Sample collection and laboratory analysis followed regulatory guidelines. The results revealed positive effects of zeolite on the total amino acid content in the meat. Glutamic acid content increased by 0.5%, and methionine levels rose by 10% in the third group compared to the control group. The protein’s chemical index also improved, indicating an increase in its biological value. Regarding fatty acids, zeolite had a minimal impact. Saturated fatty acid (SFA) content increased by 3.3% in the group with 3% zeolite (31.0±0.31g/100g) compared to the control group (30.0±0.21g/100g). Omega-3 fatty acid content remained unchanged in both the control and the 5% zeolite group (8.0±0.08g/100g), but decreased by 6.3% in the 3% zeolite group (7.5±0.02g/100g). Omega-6 fatty acids increased by 8.3% in the 3% zeolite group (13.0±1.12g/100g) compared with the control group (12.0±0.12g/100g). This study demonstrates that local zeolite improves the amino acid composition and nutritional value of protein, while helping to preserve healthy fatty acids in fish, offering new possibilities for its use in aquaculture.
