Ecological state of aquatic biocenoses in the streams of the Kola basin, Barents Sea
Abstract The ecological state of freshwater ecosystems is essential because they are actively used in human economic activities. As the habitats of valuable commercial fish species deteriorate, their population decreases rapidly. Therefore, environmental monitoring of water bodies, markedly affected...

Abstract The ecological state of freshwater ecosystems is essential because they are actively used in human economic activities. As the habitats of valuable commercial fish species deteriorate, their population decreases rapidly. Therefore, environmental monitoring of water bodies, markedly affected by human activities, contributes to efficient natural resources management. Thus, analysis of recent data on the state of river ecosystems in the Kola Bay basin is of great interest. It shows the current state of biocenoses in some of the streams flowing into Kola Bay of the Barents Sea, an environmentally unsafe area on the Kola Peninsula.
