The present research aimed to examine the effect of dietary phytoextracts supplementation on the biochemical blood parameters (glucose, urea, creatinine, total protein, albumin, ASAT, ALAT) of common carp (Cyprinus carpio L.), cultivated in a recirculation system. The fish were divided into 6 groups: one control (C) and five experimental groups in whose food was added phytoextracts of curcumin (EC), paprika (EP), thyme (ET), oregano (EO) and garlic (EG). The addition of phytoextracts had significant influence on total protein content of fish from the experimental groups (EC - P≤0.01), EP - P≤0.05, ET - P≤0.05 and EG - P≤0.05) compared to control group (C).
