The aim of this study was to evaluate the impact of different phytogenic compounds on the haematological profile and biochemical indices of carp, reared in a recirculating pilot aquaculture system. The experiment was conducted for 52 days. A basic feed, Aqua Classic type, with 46% protein and 22% lipid, was used. 5 g of different phytogenic compounds were added to form the experimental diets, as follows: V1 - control, V2 - 0.5% licorice (Glycyrrhiza glabra), V3 - 0.5% echinacea (Echinacea purpurea) and V4 - 0.5% wild thyme (Thymus serpyllum). At the end of the experiment, blood samples were taken to evaluate the haematological and blood biochemical parameters. The mean values for Ht, Hb, RBC and WBC were higher in the experimental variants than in the control. Serum protein was significantly lower (p<0.05) in variants V2 and V3 compared to the control. The serum glucose values registered significant differences between the control and the 3 experimental variants. In conclusion, the addition of phytogenic compounds in the diet has beneficial effects on the haematological and blood biochemical profile of carp (Cyprinus carpio).
