Comparative Studies on Serum Lysozyme Activities of Common Carp (Cyprinus carpio), Pikeperch (Sander lucioperca), Prussian Carp (Carassius gibelio) and Crayfish (Astacus leptodactylus)

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
