Current state and development of aquaculture in Vologda Oblast

Abstract

The article considers the peculiarities of aquaculture development and summarizes the long-term studies of establishing fish farms in Vologda Oblast. Industrial cage-type cultivation of fish (primarily rainbow trout) in volume of 3.3 thousand tons per year is recommended for 14 out of 25 water bodies investigated by the Vologda Branch of FSBSI “VNIRO”. The estimated volumes of commercial cultivation meet the requirements of environmental safety of water bodies. Currently, 19 fish farming grounds are in operation, 15 of which provide industrial cage and 4 – pasture fish farming. In the region, there are also pond fish farms and enterprises equipped by closed water supply systems. A total of 21 enterprises engaged in fish farming keep different species of sturgeon, whitefish, rainbow trout, clarid catfish, carp, grass carp and produce edible black caviar and planting (sturgeon, rainbow trout) material. The aquaculture production for 2013–2022 in Vologda Oblast has been analyzed. By 2022, commercial cultivation in the region reached 1100 tons per year.
