• Atlantic halibut (Hippoglossus hippoglossus), once abundant in the Gulf of Maine (GOM) on the northeast coast, were overfished until the stock collapsed in the 1940s.
• In 2007, a three-year tagging study using electronic tags was done by the Maine Dept. of Marine Resources.
• The objective of the study was to determine if GOM halibut migrate to spawning grounds on the Scotian Shelf and mix with Canadian halibut stock
