A multiyear archival tagging study identified consistent seasonal and daily patterns of depth-specific behavior by Greenland turbot in Alaska. These new findings provide key information for sustainably managing this commercially valuable population in a changing environment. Migration and Management of Greenland Turbot Although Greenland turbot have been well studied in the Atlantic Ocean, relatively little is known about […]
