The amino acid also differed significantly (p&lt;0.05). The nine essential amino acids found in the five species of fish were Lysine (4.21 - 6.34 g/100 g), Histidine (1.96 - 4.30 g/100 g), Arginine (5.80 - 8.21 g/100 g), Threonine (1.93 - 5.05 g/100 g), Valine (2.91 - 5.53 g/100 g), Methionine (1.74 - 3.80 g/100 g), Isoleucine (2.04 - 3.37 g/100 g), Leucine (3.64 - 7.18 g/100 g) and Phynylalanine (1.90 - 4.23 g/100 g). Whereas, the eight non-essential amino acids included: Serine (2.12 - 5.22 g/100 g), Glutamic acid (13.24 - 16.30 g/100 g), Proline (3.12 - 6.29 g/100 g), Glycine (4.20 - 9.08 g/100 g), Alanine (5.00 - 6.36 g/100 g), Cysteine (0.94 - 1.24 g/100 g), Tyrosine (2.33 - 3.33 g/100 g) and Aspartic acid (6.34 - 11.01 g/100 g). <italic>P. bane bane</italic> was first in terms of crude protein; <italic>S. mystus</italic> had the highest lipid and essential amino acid content.

The study assesses the proximate composition, amino acid profile and its content and chemical indices of the sun-dried Schilbe mystus, Bagrus bayad, Oreochromis niloticus, Clarias anguillaris and Petrocephalus bane bane from Tiga Dam Reservoir, Nigeria. The proximate composition varied significantly (p<0.05) in all five species of fish and these ranged as follows: Moisture (4.79 - 9.52 g/100 g), Crude Protein (42.20 - 57.71 g/100 g), Ash Content (0.90 - 12.51 g/100 g), Ether Extract (3.41 - 9.93 g/100 g), Crude Fibre (0.62 - 5.08 g/100 g), Nitrogen Free Extract (12.28 - 42.70 g/100 g) and Dry Matter (90.48 - 95.21 g/100 g). The amino acid also differed significantly (p<0.05). The nine essential amino acids found in the five species of fish were Lysine (4.21 - 6.34 g/100 g), Histidine (1.96 - 4.30 g/100 g), Arginine (5.80 - 8.21 g/100 g), Threonine (1.93 - 5.05 g/100 g), Valine (2.91 - 5.53 g/100 g), Methionine (1.74 - 3.80 g/100 g), Isoleucine (2.04 - 3.37 g/100 g), Leucine (3.64 - 7.18 g/100 g) and Phynylalanine (1.90 - 4.23 g/100 g). Whereas, the eight non-essential amino acids included: Serine (2.12 - 5.22 g/100 g), Glutamic acid (13.24 - 16.30 g/100 g), Proline (3.12 - 6.29 g/100 g), Glycine (4.20 - 9.08 g/100 g), Alanine (5.00 - 6.36 g/100 g), Cysteine (0.94 - 1.24 g/100 g), Tyrosine (2.33 - 3.33 g/100 g) and Aspartic acid (6.34 - 11.01 g/100 g). P. bane bane was first in terms of crude protein; S. mystus had the highest lipid and essential amino acid content. Also, C. anguillaris recorded the highest calorific value and best amino acid content. Thus, P. bane bane can serve as a source of animal protein to balance deficiencies in humans. Both S. mystus and C. anguillaris can be used as a nutrient base for high energy food and oil in the food industry.
