Summary: | Synchronism of year‐class strength was noted for the majority of commercial fish in the Barents Sea. The reason for this is probably connected with a common factor, namely the intensity of water inflow which influences spawning efficiency, zooplankton food production, fish larval drift to the feeding grounds, and consequent survival of juvenile fish. Consequently, the established regular relationships of hydrological and weather processes in the ecosystem can serve as basis for long‐term fishing forecasts. The overall pattern of the Barents Sea water circulation, long‐term climatic changes in this region, and their effect on the fish stock reproduction are considered, using Arctic cod as an example. |
