The role played by the Umba fish hatchery in artificial reproduction and conservation of water biological resources in the Murmansk region

The article provides information on the need for artificial reproduction of water biological resources. It is shown that the conservation of biological diversity of fish, maintaining stocks of valuable fish species, preserving the natural habitat is impossible without effective measures in the field of artificial reproduction. A brief description of the activities of the Murmansk branch «Glavrybvod» is given. The greatest attention is paid to the oldest enterprise in the Murmansk region – the Umba fish hatchery. The historical information about the activity of this enterprise is given. An assessment of the current state of the Atlantic salmon stocks in the Umba River basin is given. The main problems of the fish-breeding enterprise are identified and analyzed: a high level of illegal fishing, the consequences of molten timber rafting and the influence of the activities of enterprises of the mining complex. Measures aimed at solving these problems are proposed. It has been proved that thanks to the fish breeders of the Umba fish hatchery, the stocks of the Atlantic salmon population of the Umba River are replenished. It is shown that a promising direction of the plant's activity is the cultivation of other valuable fish species (whitefish, pink salmon, brown trout), which will significantly contribute to the replenishment of valuable fish stocks in the water bodies of the Murmansk region. The role and importance of artificial reproduction and conservation of water biological resources will increase more and more as the anthropogenic impact on the environment intensifies. This type of activity will be the only way to preserve the commercial value of valuable species of fish and other biological resources, which makes artificial reproduction artificial reproduction one of the highest priorities in development of fishery system of the Russian Federation.
