Fish is a vital source of high-quality protein and essential nutrients, contributing significantly to human health by preventing cardiovascular diseases, cancers, and neurodegenerative conditions. This study investigates the proximate composition and filleting yields of four commercial freshwater fish species—Nile Tilapia (Oreochromis niloticus), Catfish (Clarias spp.), Bagrus (Bagrus spp.), and Nile Perch (Lates niloticus)—from El-Mawrada Fish Market, Khartoum, Sudan. Analyses revealed significant variations in moisture, protein, fat, and ash content among species. The fillet yield was highest in Nile Perch (Lates niloticus, 49.67%), while Nile Tilapia (Oreochromis niloticus) exhibited the lowest (40.97%). Catfish (Clarias spp.) showed the highest percentage of viscera (12.58%), and Nile Perch had the lowest (6.12%). Moisture content ranged from 72.9% to 81.92%, and protein content varied between 18.9% and 20.5%. Statistical analyses confirmed significant differences (p ≤ 0.05) in carcass yields and proximate composition among the species. These findings underscore the nutritional and industrial value of these fish species, providing critical data for their use in food production and market enhancement. The study highlights the necessity of periodic evaluations to monitor the impact of environmental and industrial changes on fish composition.
