Proximate/Nutrient analyses of fresh and salt water catfish and tilapia


Erepamowei Young, Timi Tarawou

The nutritional value of fish can be defined in terms of its proximate features (% moisture, % ash, % protein, % lipid, % fibre, % dry matter) and nutrient features (Ca, Mg, Na, K, Fe, Mg, Zn, Cu, and P). In the present study, the qualities of fresh and salt water catfish and tilapia were studied via proximate and nutrient analysis. Salt water tilapia (% moisture, 92.50 ± 0.01; % ash, 3.58 ± 0.01; % protein, 34.50 ± 0.01; % lipid, 4.50 ± 0.01; % fibre, 0.42 ± 0.01; % dry matter, 7.50 ± 0.02; Ca, 0.58 ± 0.01; Mg, 0.32 ± 0.001; Na, 0.96 ± 0.002; K, 0.30 ± 0.02; Mn, 0.10 ± 0.02; Zn, 0.43 ± 0.03; Cu, 0.02 ± 0.002; P, 0.24 ± 0.03). Fresh water tilapia (% moisture, 94.60 ± 0.001; % ash, 3.76 ± 0.001; % protein, 36.40 ± 0.001; % lipid, 5.20 ± 0.01; % fibre, 0.38 ± 0.01; % dry matter, 5.40 ± 0.02; Ca, 0.36 ± 0.01; Mg, 0.23 ± 0.01; Na, 0.70 ± 0.001; K, 0.24 ± 0.01; Mn, 0.10 ± 0.01; Zn, 0.35 ± 0.002; Cu, 0.01 ± 0.01; P, 0.26 ± 0.01). Salt water catfish (% moisture, 92.20 ± 0.02; % ash, 4.00 ± 0.02; % protein, 35.80 ± 0.02; % lipid, 7.36 ± 0.01; % fibre, 0.36 ± 0.01; % dry matter, 7.80 ± 0.02; Ca, 0.42 ± 0.02; Mg, 0.30 ± 0.01; Na, 0.85 ± 0.01; K, 0.36 ± 0.01; Mn, 0.14 ± 0.002; Zn, 0.40 ± 0.02; Cu, 0.30 ± 0.01; P, 0.43 ± 0.001). Fresh water catfish ((% moisture, 94.10 ± 0.01; % ash, 5.64 ± 0.01; % protein, 38.52 ± 0.01; % lipid, 8.52 ± 0.01; % fibre, 0.25 ± 0.01; % dry matter, 6.90 ± 0.001; Ca, 0.24 ± 0.01; Mg, 0.21 ± 0.01; Na, 0.64 ± 0.001; K, 0.32 ± 0.001; Mn, 0.12 ± 0.01; Zn, 0.25 ± 0.01; Cu, 0.01 ± 0.01; P, 0.38 ± 0.01). For the proximate variables, there are significant differences between the fresh water fish samples and the salt water fish samples with less value for the salt water samples except %fibre and %dry matter. The results show significant differences between fresh and salt water samples with higher values for the salt water samples except phosphorus. The salt water fish samples have higher nutrient values than the fresh water fish samples.
