Abstract :In the present study, the usability of Prussian carp (Carassius gibelio) meal (PCM) as an alternative animal protein source in fish feeds was investigated by comparing it with anchovy (Engraulis encrasicholus) and sprat (Sprattus sprattus) meals in terms of their biochemical, fatty acid, amino acid and element compositions. Prussian carp were obtained by fishing and made into a meal (PCM). Anchovy (AM), and sprat (SM) meals were purchased from a commercial company. The amino acid analysis results show that PCM\\\'s total, essential, and non-essential amino acid values were lower than that of AM and SM (P < 0.05). The polyunsaturated fatty acids (PUFA) and Omega-6 values of PCM were higher than AM and SM; and lower than saturated fatty acids (SFA), Omega-3, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), atherogenicity index (AI) values (P < 0.05). According to the element analysis, the P and Ca values of the PCM were higher than the AM and SM (P < 0.05), and the Na, K, Fe, Cu, Zn and Se values were lower. According to the results of the present study, PCM can be utilized in the feed industry to boost the sustainability of fish meals used in feed production, which in turn will reduce the foreign dependency on vegetable and fish meals, and lower feed costs.
