The Current State of Carp Breeds Bred in Western Siberia

Abstract

AbstractOn the territory of Western Siberia, two officially registered carp breeds are currently being bred in Russia: the Altai mirror carp and the Sarboyan carp. These two breeds are different in origin. Altai mirror carp is a descendant of Galician carp imported in 1936 to ponds in the Altai Territory, and then for eight breeding generations, selection was carried out to increase body height, girth, high fertility and growth rate. The Sarboyan carp was obtained by crossing the Ropshinsky carp and the Amur carp. The crossing was carried out to increase winter hardiness and adaptability to low values of oxygen dissolved in water. Currently, breeding of breeds takes place at different intensity of selection. Breeding work with the Altai carp is carried out constantly and is aimed at maintaining its breed characteristics. Unfortunately, the Sarboyan carp bred in three breed types has lost its herds and currently there is one of its types, the northern type. But due to the fact that breeding work with him has not been carried out for 20 years, the degree of selection was low, individuals by physique deviated to the carp type. Their b body became shorter, and their absolute body length increased. The fish do not have a characteristic carp hump behind the head and belong to the 2nd breeding class. Class 1 fish make up only 1.9% of the herd.KeywordsCarpWestern SiberiaThe pondsSelectionBreedingSexual dimorphismA femalesA malesA body condition indices
