Nutritive value of three fresh Nile fishes Schilbe uraniscopus (Shelbaya), Aleste sdentex (Kawara), and Alestes nurs (Hemeala

Abstract

The aim of this study was to evaluate the nutritive value of three fresh fish species; Schilbe uraniscopus (Shelbaya), Alestes dentex (Kawara), and Alestes nurse (Hemeala). The study samples {18 fish, six for each species} were collected randomly from Elmawrada fish market in Omdurman, Sudan during the period from December 2010 to April 2011. And preserved with ice in thermostatic container, and then taken to the Laboratory. Proximate analysis was done to determine moisture %, ash %, ether extract % crude protein %, dry matter %, and Nitrogen free extract%. The result was 76.50 %, 23.60%, 4.30%. 32.00%, 7.905, 32.00% Schilbe uraniscopus,77.04%, 22.90 %, 4.10 %, 32.50 %, 7.60 %, 32.80 % Alestes dentex and 72.90 %, 27.20 %,4.60 %,31.00 %, 30.00 % ,7.20 % for Alestes nurse. The protein percentage, Fat, Moisture and Ash differed significantly (p < 0.01) among the three species
