英语. In course of the research there were worked out the technological methods of growing the merchantable carp of increased weight conditions at two years circulation allowing to obtain two year old carps of mass over 500 g in the conditions of the Republic of Belarus with capacity from 8.5 to 10.6 c/ha. The research was realized in the conditions of the Republic of Belarus in profit-and-loss management ‘Vilejka’ in (Minsk region) in 2012 -2013 at 12 experimental ponds, with a total area of 2.88 ha and two production fish farm ponds ‘Beloe’ of the Gomel region, with a total area of 126 ha. As a result of realized hematological research there was revealed the optimum planting density of large carp yearlings in growing of two-year trade bions. It was found that for the two-year trade bions with weight 650 g and fish productivity of 8.5 c/ha a stocking density of carp yearlings with average weight of 50 grams must be 2.2 thousand ind./ha, weighing 508 grams, and fish productivity of 10.6 c/ha – 3.6 thousand ind./ha. The analysis of the production process of growing commercial carp fish farms in the country was done.
