dc.description.abstractThe proximate, amino acid, nutritional values and mineral contents of fourteen fresh water fish families viz: Cichlidae, Bagridae, Mochokidae Cyprinidae, Clariidae, Characidae, Mormyridae, Schilbeidae, Citharinidae, Centropomidae, Distichodontidae, Gymnarchidae, Osteoglossidae and Malapteruridae comprising of fourty species collected from Tiga dam, Zaria dam, Shiroro dam and Niger-Benue Confluence were determined using standard procedures of AOAC (1975 and 1980), Winberg (1971), TSM, FA) (1973) Atomic Absorption spectrophotometer (AAS), Flame photometer and Spectronic 20. The carbohydrate, lipid and protein were generally in the ratio of 1:2:4. The range of the nutrients contained were moisture 70.20-79.60g/100g wet weight, Ash 2.40 - 39.70, Organic matter 60.00 - 98.00, Carbohydrate 4.60 - 28.30, Lipids 15.80 - 56 40, protein 28.10 - 58.30g/100g dry matter while the calory was 235.62 - 728.90 k cal./l00g organic matter. These range of values were found to be within the range recommended for human of all ages. Seventeen amino acids were also observed with significant difference (P<0.05) between the most prominent was glutamic acid and the least prominent was mainly methionine. However, the essential amino acids contained in all families had values indicating that fish proteins are of good quality, this was confirmed by the high values of Essential to non essential ratio, Essential to total nitrogen, Essential to protein ratio, Essential amino acid index and protein scores. The results also indicated that calcium dominated the mineral pool and the least was copper. The fresh water fishes were good sources of dietary minerals. There was no significant difference (P>0.05) in all nutrients contained in fishes collected from the four locations, however some nutrients were significantly higher (P<0 05) during the wet seasons. viien_US
