Abstract
The purpose of the work: to describe the variability of cod fishes stocks and catches in the Far Eastern seas and the Pacific waters of Kamchatka and the Kuril Islands and to assess the prospects for their fishery.
Methods used: to achieve this goal, data on the biomass and catches of walleye pollock, Pacific cod and saffron cod for the period from 1935 to 2025 were analyzed. Calculations were made for fish in general, for individual habitats and local stocks.
Novelty: the novelty elements include generalized materials on the reserves and catch of cod fishes resources in the Far East for the entire period of their study and fishery. In total, information on 30 groups of walleye pollock, Pacific cod and saffron cod living in the study area was considered, the dynamics of their biomass and catches were shown. Trends and cyclicality of stocks and catches of fish of individual stocks were revealed. The periodicity of the formation of cod fishes stocks made it possible to present forecast estimates of the expectation of high estimates of their abundance for the period 2026-2038. Geographical localization in the sequence of formation of biomass maxima of individual fish populations was also revealed, the clarification of the reasons for which will serve as the basis for further research.
Practical significance: the information obtained can become the basis for a long-term action plan for the effective use of cod fishes stocks, which are fundamental for Russian fishery.
