ABSTRACT. The present study was undertaken to evaluate humoral indices response in sturgeons reared under controlled conditions and treated with exogenous lysozyme dimer in immersion. Fish of average body weight 40±4 g were bathed for 30 minutes in 0.1 mg l-1 of dimer (Lydium KLP-602). After the treatment, blood was sampled from the fish for 7 weeks, at weekly intervals. Lysozyme activity, the level of -globulins, ceruloplasmin, and total protein were measured in blood serum. Average body weight of fish increased 5 fold (to 210±12 g) during the experiment. In treated fish the bacteridytie activity of endogenous lisozyme, -globulins, and ceruloplasmin levels increased already in the first week after immersion by 27%, 40%, and 60 % respectively. Increase of these parameters was observed until the end of the experiment. The results indicate that lysozyme dimer stimulated humoral responses in fish.
