During this period, the water contains the most nutrients and food. This is done to maintain fish diversity and improve catch quality.

Such activities were carried out on Lake Dolgoe within the territory of the "Dolgoe" hunting complex of the Lepel Forest Enterprise. The process was coordinated by representatives of interested services – the Department of Agriculture and Food of the District Executive Committee, the Lepel Forest Enterprise, the Inspectorate of Natural Resources and Environmental Protection, and the Inter-district Inspectorate of Fauna and Flora.

The number of individuals released into the water is 1250, and their total weight is 320 kilograms. Incidentally, the lively carps were delivered to the Lepel region from the "Gritsеvo" fish farm of the Molodechno district.
