The variability of immuno-physiological parameters of juvenile european catfish (Silurus Glanis) in ontogenesis
For the domestication and breeding of animals it is important to study the variability of estimated characteristics. In the present work the results of studying the variability of blood parameters of juvenile catfish common in ontogenesis. The smallest variability among different age groups of catfish (fingerlings, two-year and three-year) observed in the percent of Mature red blood cells of all cells of the erythroid series; the percentage of lymphocytes in leukogram; of transaminases, glucose, total protein, albumin and cholesterol in serum. As well as the content of lysosomal cationic proteins in the neutrophils of blood.
