Proximate Composition and Some Mineral Contents on Flesh of Tetradon Fahaka and Synodotis Schell Fish from River Nile

Abstract

Proximate composition (moisture, protein, fat, ash, fiber) and some minerals (iodine, zinc, and iron, copper) content in the flesh of two fish species, Tetradon fahaka and Synodotis schell were investigated. Statistical analysis using ANOVA showed significant differences in the values of the moisture and fat in the two fishes studied (P<0.05). In terms of percentages, moisture content was highest in Synodotis schell (72.1±0.3 %) and lowest in Tetradon fahaka (70.6±0.7 %). Fat content was found to be highest in Tetradon fahaka (2.1±0.8 %) and lowest in Synodotis schell (1.7±0.6 %), there were no significant differences in protein, ash and fiber content while minerals showed significant differences in the content of Iodine, Zinc and iron there was no significant differences in copper content. Iodine and iron were highest in Synodotis schell (0. 24 mg/kg) and (0.19mg/kg) respectively. While Zinc was highest in Tetradon fahaka (0. 3 ppm).
