Abstract

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&lt;0.05). There was a significant difference of serum lysozyme levels between spring and autumn in common carp, prussian carp and crayfish (p&lt;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.

Highlights

Fish and crayfish are interaction with a wide range of pathogenic and non-pathogenic microorganisms in the aquatic environment and have complex defense mechanisms for their survival
Field Sampling of Fish Common carp, prussian carp, pikeperch fish, and crayfish used in this study, were obtained from Egirdir Lake in Turkey
The highest lysozyme activity was detected in pikeperch (0.944 mg ml-1). prussian carp (0.236 mg ml-1) and crayfish It was followed by common carp (0.256 mg ml-1), (0.227 mg ml-1), respectively (Figure 5)

Summary

Introduction

Fish and crayfish are interaction with a wide range of pathogenic and non-pathogenic microorganisms in the aquatic environment and have complex defense mechanisms for their survival. Comparative Studies on Serum Lysozyme Activities of Common Carp (Cyprinus carpio), Pikeperch (Sander lucioperca), Prussian Carp (Carassius gibelio) and Crayfish (Astacus leptodactylus). Lysozyme level or activity is an important index of innate immunity of fish, due to the high concentration of these leukocytes in the anterior hematopoietic portion of the kidney (Saurabh and Sahoo 2008).
