Abstract:
This research is aimed at comparing the nutritional profiles of African catfish fed with commercial diet in earthen and concrete ponds. A total of 500 fingerlings were randomly distributed into Earthen (4 x 8m2) and Concrete (1 x 2m2) ponds with 400 and 100 fingerlings respectively. The fish were fed 5% of their body weight twice daily for 84days. The fish sampled from each treatment were smoked-dried and milled into powdered form. The proximate: Protein (Pro), Moisture (Moi), Fat (Fa), Fiber (Fib), Ash (Ah), Carbohydrate (CHO) and mineral compositions of the powdered fish were determined using the standard methods of analytical chemists. Results showed that highest values were recorded for Potassium K (88.25±0.04), Sodium Na (72.36±0.00) and Copper Cu (0.36±0.47) in earthen pond and Calcium Ca (240.58±0.04), Manganese Mn (0.15±0.00), Iron Fe (8.17±0.01) and Zinc Zn (1.26±0.01) in concrete pond respectively. The ash content showed that there was no significant (p0.05) differences in moisture, fat, fiber, protein and carbohydrate contents of fish reared in both ponds. The significant differences in the ponds chemical compositions might be due to the differences in the environment and nutrient utilizations that they were subjected to. These attributes differing significantly between earthen and concrete pond shows that they were in good condition for human consumption, but for better enhancement, fish raised in earthen pond should be consumed more as it shows higher protein content.
