Nutrition is a determining factor in the growth potential of fish. The high costs of fodders have created the need for research of substitutes that will contribute to improving the growth performance and that will achieve high-quality fish products. Many by-products in the food industry are rich in bioactive nutrients, with the potential to serve as functional food ingredients for fish fodder. The aim of this study is to determine how the growth parameters and composition of carp meat (Cyprinus carpio), reared in a recirculating system and fed with diets that have grape marc as a fodder component, are influenced. The inclusion of grape marc in fodders ensures increased growth performance compared to diets without the addition of grape marc, and a feed conversion ratio (FCR) with better values in the experimental lots (1.48 for lot T2, 1.67 for lot T1, 1.62 for lot T3) compared to the control lot C (1.86). Grape marc used as supplement in diets, determined the accumulation of protein and lipids in carp meat, an increased intake of fatty acids, an improvement in the ω3/ω6 ratio, causing an increase in the nutritional value of fish.
