Popis: This study was conducted to evaluate the effects of a dietary earthworm meal mixture (earthworm meal: EM and wormcast: WC) for replacing fish meal (FM) on growth performance, antioxidant capacity, lipid metabolism, and intestinal health of common carp (Cyprinus carpio L.). FM was used as the protein source in the control diet (D1), while 30% FM protein was replaced with an EM and WC mixture in the experimental diets, and the specific mixing ratio was as follows: D2 (15.4% EM), D3 (15.1% EM and 1.8% WC), D4 (14.8% EM and 3.7% WC), and D5 (14.5% EM and 5.8% WC). The growth performance was significantly decreased in the D4 and D5 groups compared with the D1 group, while the condition factor was highest in the D2 group (P
