The evaluation of
nutrient composition in adult Chrysichthys nigrodigitatus
(CN), Clarias gariepinus (CG) and Heterobranchus
(HB) was determined on wet basis. A total of
60 samples (weight: 500g – 1kg fish) comprising 20 of each
species were gutted, washed, ground and analyzed for
moisture, protein, fat, ash and carbohydrate, using standard
methods. Results showed the mean values for moisture,
 protein and fat as 72.53+ 0.23 (CG) – 80.73+
0.23% (HB), 18.20+ 0.13(HB) – 21.37+ 0.13% (CN)
and 2.13+ 0.10 (CN) – 7.25 + 0.10% (CG). The
carbohydrate and ash values ranged 1.33+ 0.19 (HB) –
2.55+ 0.19% (CG) and 1.63+ 0.09 (HB) – 3.30+
0.09% (CN). The caloric values for protein was 13.27+
0.14 (CN) – 17.22+ 0.14 Kcal/100g (CG), fat showed
27.26+ 0.19 (CN) – 57.31+ 0.19 Kcal/100g (CG)
and carbohydrate 1.17+ 0.34 (HB) – 1.35+ 0.34
Kcal/100g (CN). The nutrients showed significant differences
at p< 0.001 between the fishes examined. These catfishes
were observed to contain adequate quality animal protein,
fat and ash that would provide appreciable amounts of
essential nutrients such as amino acids, fatty acids,
minerals and energy to support human health.
