Evolutionary Origins and Prospects for Interaction between Invasive Pink Salmon and Natural Populations of Atlantic Salmon in the White Sea–Barents Sea Basin (Review)

The specifics of the adaptive processes in the evolution of salmonids, which underlie the formation of modern natural habitats, are examined, and substantiated adjustments to the structure of the Salmoninae subfamily are proposed. Prospects for developing effective technologies for the conservation and restoration of natural Atlantic salmon populations are analyzed, as are approaches to increasing fish productivity in the region’s waters by increasing Atlantic salmon numbers and monitoring an invasive species (the Far Eastern pink salmon). For pink salmon, a promising approach is to monitor populations in large and small rivers separately, combined with hatchery propagation, and to carry out complete harvesting in small rivers without permitting escapement to spawning grounds.
