Movements of a deep‐water fish: establishing marine fisheries management boundaries in coastal Arctic waters
Abstract Management boundaries that define populations or stocks of fish form the basis of fisheries planning. In the Arctic, decreasing sea ice extent is driving increasing fisheries development, highlighting the need for ecological data to inform management. In Cumberland Sound, southwest Baffin I...

Abstract Management boundaries that define populations or stocks of fish form the basis of fisheries planning. In the Arctic, decreasing sea ice extent is driving increasing fisheries development, highlighting the need for ecological data to inform management. In Cumberland Sound, southwest Baffin Island, an indigenous community fishery was established in 1987 targeting Greenland halibut ( Reinhardtius hippoglossoides ) through the ice. Following its development, the Cumberland Sound Management Boundary ( CSMB ) was designated and a total allowable catch ( TAC ) assigned to the fishery. The CSMB was based on a sink population of Greenland halibut resident in the northern section of the Sound.
