  Evaluation of nutritional composition was carried out on Clarias lazera fish while functional properties were also investigated. The proximate composition were total ash (8.6%), moisture (7.5%), crude protein (73%), crude fat (8.3%) and carbohydrate (2.5%); crude fibre was not in the detectable range. The available energy was high (1.59 MJ/100 g). The proportion of energy due to protein and fat were 78.0 and 2.7%, respectively. The fish sample was low in sodium Na, potassium (K), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), chromium (Cr) and lead (Pb). Calcium (Ca) was the most highly concentrated mineral (63.7 mg/100 g sample). The total amino acid was 925.2 mg g-1 crude protein while lysine (Lys) was the most highly concentrated essential amino acid (79.0 mg g-1). The fish sample had a balanced content of essential amino acid in isoleucine (Ile), leucine (Leu), lysine (Lys), methionine (Met) + cystine (Cys), phenylanine (Phe) + tyrosine (Tyr) and threonine (Thr), with respect to the FAO pattern while supplementation may be required only in valine (Val). The calculated isoelectric point (pI) was 5.6, Predicted Protein Efficiency Ratio (P-PER) was 26.1 and first limiting amino acid was Val. Results of functional properties were: foaming capacity (4.9%), foaming stability (3.7%, 8 h), water absorption capacity (280.5%), oil absorption capacity (280.6%), oil emulsion capacity (20.0%), oil emulsion stability (19.5, 12 h), lowest gelation concentration (10.0%) and bulk density (470 g L-1). The results showed that Clarias lazera could be a good source of most of the parameters determined in this study.
