Sturgeon breeding as the basis for forming a food base in the Arctic zone of the Russian Federation

Abstract

The article provides an analysis of sturgeon breeding, as well as materials for assessing the reproductive indicators of the Siberian sturgeon breeding stock in the conditions of the Arctic zone. The experience gained as a result of the multi-year research allows us to consider sturgeons, in particular the Siberian sturgeon, to have great potential for use in the Arctic zone of the Russian Federation. The cultivation of this species in the Northern regions may have great prospects for the formation of a food base, since it has high fish-biological, physiological and reproductive indicators when using various aquaculture technologies. The best productive indicators were obtained when sturgeon was reared in recirculating aquaculture systems (RAS), however, the experience of using the cage method showed a good physiological state of the fish. All the studied methods can be applied for the development of aquaculture in the Arctic zone of the Russian Federation. The cage method can be recommended for reproduction purposes, while using RAS can be recommended for fish rearing for sale.
