Specific features of the feeding of juvenile atlantic salmon (Salmo salar L.) in the subarctic varzuga river and its small tributaries (Kola Peninsula)

An analysis of the spectrum and intensity of salmon parr feeding and the structure and abundance of zoobenthos in the main channel of the river and its small tributaries has been made. It has been shown that young salmon in small tributaries feed more intensively. The biomass of the main food objects of juvenile salmon in the tributaries was significantly higher than in the main channel. In small tributaries, thus, feeding conditions are more favorable for the growth of juvenile salmon.
