AB: The fisheries of the North Pacific and Bering Sea (NP/BS) have been fully exploited since the 1960s, with some of the more valuable fisheries dating back a century and longer. Many of the fisheries exhibit trends in productivity over a range of time scales. Debate on the causes of the productivity trends dates back to the 1950s (the "Thompson-Burkenroad" debate) and continues to this day. It is now widely recognized that environmental forcing, including the Pacific Decadal Oscillation and the El Nino-Southern Oscillation, contributes substantially to the observed variability in fisheries production. In this review, I will illustrate the historical trends in NP/BS fisheries, highlighting spatial and temporal commonalities/differences across species. Pacific halibut and Pacific salmon, which have been exploited for the longest period and for which the longest time series of data exist, will be discussed in greater detail. I conclude with a summary of proposed mechanisms linking climate variability and control of NP/BS fisheries production.
