Role of the geologic medium in forming bioefficiency of hydrobionts of river basins and the Arctic shelf

The paper is dedicated to the problems of bioproductivity and species variety of salmon on Kamchatka. The author explains it by integration of the salmon biological system in geologic carboniferous systems, the integration ensures sufficient feed basis to salmon, which fry is being fattened in the native river during four years. The foundation of the feed pyramid is carbonaceous substance of the geologic systems including mineral organic carbon, mineral plankton, humic acids. The mineral organics is converted to albuminous nutrition of zooplankton of spawning rivers by a microbiological way. The specialization of bacteria in freshwater, mixed and sea basins has been represented. Carrying out by the rivers of the Arctic ocean basin, England, Northwest of the Pacific ocean of carbonaceous substance has been considered as a natural mechanism of supply of hydrobionts by feed basis.
