Ecological Features and Opportunities for Economic Use of the Solovetsky Archipelago Freshwater Ichthyofauna

Abstract

The species composition and taxonomic diversity of the Solovetsky Archipelago freshwater ichthyofauna were revealed, and a description of the current state of the fish was given. The belonging of fish to freshwater faunistic complexes and ecological groups (nature of feeding and mode of natural reproduction) was examined. Currently, 14 species of fish were found in the inland waters of the Solovetsky Islands, including local and alien species with varying degrees of acclimatization effect. A possible annual catch of freshwater fish has been established, which could be considered optimal. If it is necessary to organize freshwater aquaculture, pasture cultivation in the lakes of the Solovetsky Archipelago of the whitefish complex seems promising. It is based on the collection and fertilization of eggs at temporary fish breeding stations, its subsequent incubation at fish farms and the release of reared juveniles into feeding lakes.
