Comparative characteristics of the results of wintering of new selection groups of carp: the created breed “Belarusian mirror” and scaly carp, the selection of which is aimed at improving reproductive qualities

The article presents the results of wintering of each age group of the broodstock of two lines of mirror carp and scaly carp bred in Belarus, the selection of which is aimed at improving reproductive qualities. The results of wintering of the bred carp were compared with collection lines of Belarusian and foreign selection, the wintering of which took place together with the selection material, that is, in the same conditions. In general, the broodstock and producers of the bred carp were characterized by wintering indicators close in value to the regulatory requirements. Some decrease in the survival rate of yearlings of the bred mirror carp was noted compared to purebred groups from the collection stock. In older bred groups and producers, an increase in the exit from wintering was observed compared to carp lines that wintered in the same conditions (together). In terms of the level of body weight loss during the wintering period, all age groups of selective carp were characterized by significant advantages compared to regulatory requirements.
