The aim of this study was to compare the effect of feed mixtures with different proportion of cannabis products on fingerling of common carp (Cyprinus carpio L.). The addition of hemp cake to feed was tested. The feed experiment was conducted in period 21.9.2016 - 21.11.2016 in recirculation system consisting of 10 tanks of 200 l volume connected to a biofilter. During the experiment, control weight measuring was performed and the hydrochemical and physical parameters in every tank were recorded. Fish were fed feedstuff with 5 %, 10 % and 15 % of hemp cake. On average, the fish grew from 35.37 grams to 57.24 grams. The best feed conversion ratio (FCR), specific growth rate (SGR) and ratio of these two values achieved fish fed feeding mixture number 2 with 10 % of cannabis cake (FCR 3,14, SGR 0,83 %, FCR/SGR 3,96). Statistical significant influence of feed mixture on content of proteins, fats and n-3 fatty acids in carp muscle was not proven.
