Abstract: The impact of applying NuPro® (40 g/kg feed) and levamisole (300 mg/kg feed) in European pikeperch (Sander lucioperca) diets with vegetable oils on growth, immunological, hematological, and blood chemical parameters was assayed. The fish were fed the feed containing sunflower and linseed oils (48 and 21 g/kg feed) (group VO) or this feed with levamisole (group VOL) or NuPro® (group VON). The fourth group was fed the feed with fish oil added in the amount of 69 g/kg feed (group FO). The pikeperch were reared for 56 days. Feeding the fish feed supplemented with levamisole or NuPro® increased the immunological responses of the phagocytes and lymphocytes, lysozyme activity, and total gamma-globulin levels. The feed supplemented with NuPro® resulted in decreased aspartate and alanine aminotransferase and alkaline phosphatase activity. Vegetable oils in the feed were linked to increased contents of linoleic acid in fish bodies. The quantity of eicosapentaenoic and docosahexaenoic acids was significantly the highest in group FO. The immunological index obtained in group VON indicated that the diet supplemented with brewer's yeast extract (NuPro®) was the most advantageous when feeding juvenile pikeperch feeds with vegetable oils.
