Annotation	The aim of this study was to evaluate the efficiency of feeds with the addition of various algae and cyanobacteria. Common carp (average body mass of 19.6 ± 3.49 g) were randomly divided into 4 groups and fed a commercial feed (control group), the same commercial feed with the addition of 10 % of dry green algae of the genus Chlorella (chlorella group), dry biomass of algae from waste water treatment (algae group), and lyophilized toxic cyanobacterial biomass of the genus Microcystis (microcystis group). After 29 days of the experiment, standard indices for the assessment of feed utilization, external characteristics, fish condition, chemical composition of muscles and composition of fatty acids were measured. The feed variants with the addition of green algae (chlorella and algae groups) appeared to be nutritionally more favorable in our experiment. A higher content of PUFAs and total amount of fats (expressed in units of weight) were found in the groups of fish fed the green algae and algae from waste water treatment supplemented feed.
