Abstract. Extraction valuable products from fish waste such as protein, lipid has gained more research attention
around the worldwide. In this study, a fish waste was subjected to approximate analysis to determine the nutritional
composition includes protein, lipid, and carbohydrates as well as moisture and ash content. The fish waste included
scales, fins, and bones isolated from Cyprinus carpi fish samples. The fish samples were divided into three samples
groups and named G1, G2, and G3.The results showed high protein content in fish waste and the highest value 27.3
% found in bones (G3). The highest value of lipid content also was recorded in bones 7%. The higher moisture
content was detected in scales parts 73% accompanied with a significant difference (P-value <0.05) in the scales
moisture contents among the three fish waste groups. In addition the results revealed that the protein and lipid
content increased with increasing weight and size of fish. In general, this study presents a high nutritional value of
fish waste, providing another a viable source for sustainable food industry.
