Abstract: | The zooplankton of 23 small salmon rivers of the White Sea and Barents Sea basins in the Kola Peninsula were studied. The
species composition and quantitative indices in juvenile salmonids habitats are characterized. The maximum species diversity
and abundance of planktonic fauna were recorded in lake-regulated rivers and places with large quantities of water. The quantitative
development of zooplankton in rivers is low, which testifies to its minor role as a food resource for salmonid juveniles.
The assessment of the ecological state of the river water is presented. |
