| dc.description.abstract | Three species of fresh Water fishes from Zaria dam (Alestes nurse; Synodontis Schall and Tilapia zillii) were analysed for their water, fat, carbohydrate, total organic matter, protein, amino acid, ash, and mineral contents and also for their calorific values, using ten samples of each. The results shows that the three speciea contain the same percentage of body water content, but different fat, carbohydrate, organic matter, protein, amino acid, ash, mineral contents and calorific values. A. nurse, S. schall and T zillii, are of low fat content, (17.40g, 9.55g and 12.33g/100g dry weight, respectively). The three species contain high amounts of protein (69.94g/100g for A. nurse, 61.91g/100g for S. schall and 54.36g/100g for I. zillii). The carbohydrate content of the three species was found to be very low as shown by the values 2.52g/100g for A. nurse, 14.16g/100g for S. schall and 13.38g/100g for T. zillii. The calorific values of the three species shows that proteins contribute a lot to the calorific value than carbohydrate and fat. nurse has the highest mean calorific value of 55B.40Kcal/100g followed by T. zillii with a value of 500.6lKcal/100g and lastly S. schall with a value of 490Kcal/100g. From the amino acid analysis, the following amino acids were found to be present in equal amounts in the three species; (i) lysines (ii) histidine, (iii) arginine, (iv) valine, (v) alanine (vi) threonine (vii) glutamic acid (viii) Methionine (ix) tyrosine and (x) phenylalanine. Variations were observed only for (i) aspanftic acid (ii) glycine (iii) serine (iv) proline, (v) isoleucine and (vi) leucine values. S. schall was found to be richer in all the mineral elements investigated than A nurse and T. zillii. High levels of calcium and phosphorus content were recorded for the three species, while potassium sodium, and magnesium are present in appreciable amounts. However, zinc, iron and copper are present in very small amounts in the three species. Suggestions have been made for further investigation into the mineral and vitamins content, as well as the fattyacid composition of the fat. Marine and brackish water fish samples have been suggested to be investigated along similar lines for a comprehensive chemical data for fishes obtained in Nigerian waters. | en_US |
