Physiological and immunological features of males and females of the immunologically resistant carp breed (Cyprinus carpio L.)

Selection on increased immune stability is one of the most radical opportunities to strengthen the resistance of animals. Especially in the actual conditions of intensive farm cultivation, with unilateral selection on efficiency when there is a decrease in resistance of the individuals against diseases. It is important in bigger measure for fishes as they are hydrobionts and water habitat leaves the mark on their activity. Besides, the poikilothermic fish increases their vulnerability to any invasion of pathogens and causative agents of diseases. From the breeds of a carp which are available now, only Angelinsky breed passed long selection on resistance to rubella (a poly etiology disease which activators can be a virus of a spring viremia carp, aero monads, pseudo-monads). Selection was carried out on a provocative background. Quantitative characteristics of the increased resistance of an Angelinsky mirror carp were shown at statement of biological tests with causative agents of diseases. The purpose of this research was the comparative analysis of hematological, biochemical and cytochemical indices of Angelinsky producers and productive carp breeds. Analysis of the results showed that the fall in adult carp, the recovery after spawning and preparing for the hibernation is expressed by the activation of hematopoiesis, the proportion of mature segmented neutrophils. The pattern for all age groups of Angelinsky carp regardless of the season of the year is the high level of metabolism, AST and albumin (protein metabolism) and triglycerides (energy metabolism).
