Regime shifts and recruitment dynamics of snow crab, Chionoecetes opilio, in the eastern Bering Sea
Abstract Shifts in climate regime are prominent features of the physical environment of the eastern Bering Sea and in recent years have been documented in approximately 1977 and 1989. Average snow crab ( Chionoecetes opilio ) recruitment decreased sharply after the 1989 fertilization year. Models in...

Abstract Shifts in climate regime are prominent features of the physical environment of the eastern Bering Sea and in recent years have been documented in approximately 1977 and 1989.

These models are evaluated using cross‐validation and retrospective analysis, both of which indicate that the relationships are relatively robust to varying levels of information.
