Description
Summary:No abstracts are to be cited without prior reference to the author.Fisheries are subject to major changes of state driven by ocean-atmosphere interactions. In the North Pacific, ecological changes are associated with the relative strength and position of the Aleutian low pressure system. These have driven changes in fisheries, including increases in sardine catches of 10 million tonnes off Japan and Peru. In the North Atlantic, fluctuations in the relative strength of the high pressure systems off the Azores and at Greenland have major effects on the Atlantic ecology and fisheries. Cod and haddock at Greenland need a negative NAO index. The gadoid outburst in the North Sea was associated with high recruitments during periods of negative NAO index. ...
