It has good quality of meat for both consumption and industrial processing. Th e quantity of by-products obtained during primary processing of bighead carp and chemical characteristics of internal organs were investigated in this paper. Th e total average weight of by-products was 760.45 g (42.31%) in relation to live body weight, which<br>was cca 1797.5 g. Th e by-product contributing to the largest quantity to total live body weight was the head with 529.39 g (29.45% of live body<br>weight), followed by complete internal organs and tail and fi ns, which weighed 137.67 g (7.66%) and 68.82 g (3.83%), respectively Chemical composition of internal organs of bighead carp was mostly water (60.99%), following by crude fats and crude proteins (21.20% and 10.61%, respectively). The low collagen content (15.25% of total crude protein) indicates the high nutritional quality of protein content from internal organs. Nitrogenous complexes from the internal organs were predominantly proteins. Digestible nitrogen was approximately equal to total nitrogen (92.04%), indicating that all proteins of the internal organs had high biological value. Based on the results obtained, it can be concluded that bighead carp internal organs could be important sources of proteins and fats, and thus, could be used in Serbia as a raw material for feed and technical fat production.</p>}, number={2}, journal={Archives of Veterinary Medicine}, author={Okanović, Đorđe and Ristić, Milutin and Kormanjoš, Šandor and Tasić, Tatjana and Ikonić, Predrag and Branislav, Šojić and Pelić, Miloš}, year={2017}, month={Dec.}, pages={3–12} }
