In this study, serum lysozyme activity was studied by the agar well diffusion assay in various species of fish (common carp, Cyprinus carpio, pikeperch, Sander lucioperca, prussian carp, Carassius gibelio) and crayfish (Astacus leptodactylus) obtained from three different regions in spring and autumn in 2013. The highest levels of lysozyme activity were found in pikeperch fish, followed by common carp, prussian carp, and crayfish, respectively. There was no significant difference between common carp, prussian carp, and crayfish, but it was found a significant between pikeperch fish and the other species (p<0.05). There was a significant difference of serum lysozyme levels between spring and autumn in common carp, prussian carp and crayfish (p<0.05). There was no significant difference between seasons in pikeperch fish. These results showed different of the lysozyme activity in the fish innate immune system in the aquatic ecosystem of different species.
