Carp appears a traditional fishery object in the Republic of Belarus and average weight of carp's underyearlings is calculated in the size of 25 g. But in regions with unstable temperature regime (Minsk, Mogilev and Vitebsk regions) standard weight gain of fingerlings is not achieved due to temperature fluctuations. It leads to the enlargement of the period of fish growing and increases self-cost of fish production. The article analyzes the parameters for obtaining large carp underyearlings with the weight of 50-80 g in the conditions of the second fishery zone of Belarus. The research has been carried out in the conditions of experimental ponds. The object of the research appear fingerlings of industrial breeding and natural spawning. Normative characteristics of growing of fish larvae appear the control base. Feeding of the fingerlings has been carried out twice a day; vegetation period of growing composes 120 days. Dependence of final mass of carp fingerlings on stocking density is analyzed; influence of stocking density of carp underyearlings on their fish productivity is evaluated.
