Оценка эффективности выращивания сибирского осетра (Acipenser Baerii Brandt) в условиях Европейского Севера Аннотация. В работе представлены материалы по выращиванию сибирского осетра ленской популяции (Acipenser Baerii Brandt) в условиях северных регионов. Отмечено, что, несмотря на сложные климатические условия Европейского Севера, биологические особенности сибирского осетра позволяют достаточно эффективно выращивать его до товарных размеров, а также получать половые продукты высокого качества.

The article presents materials on the state of the fisheries complex of the Republic of Karelia and the peculiarities of personnel training for this industry at Petrozavodsk State University. It was noted that in the process of developing aquaculture and increasing the production of fish products from 2001 to 2021, the system of training students was improved, educational programs of various levels were developed, allowing the production of in-demand specialists. As a result, the high importance of PetrSU in providing personnel for an actively developing industry in the region is shown. The article analyses educational programs of different levels. It is noted that modern educational technologies are used in the learning process, good material and the technical, scientific and practical base is used. The training of qualified personnel is of great importance is also a high level of practice-orientation of all programs and active participation in the training of enterprises of the fisheries complex. Thanks to this, the most important professional competencies necessary for graduates at the present stage are implemented when teaching students. This experience allows us to train high-level specialists and thus actively participate in developing the fisheries complex of the Republic of Karelia, forming its human potential.

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.
