Investigation of Local Fisheries Resources of the Labrador Coast

     Dr. Joe Wroblewski and  his graduate students are investigating local fisheries resources of the southeastern Labrador coast which are utilized by coastal communities, but which have not been scientifically documented. We are working with Labrador residents to study the ecology of these living marine resources. We have focused on bay cod and Icelandic scallop, specifically to understand the productivity of the wild stocks and the potential for aquaculture (Wroblewski et al., 1998).
     One of our projects is located in Gilbert Bay, southern Labrador. From a historical description of the Labrador cod fishery (Powell, 1987) and interviews of local fishers by regional officers from the provincial fisheries department, we learned of the existence of a local population of northern cod in Gilbert Bay (Wroblewski, 2000). These bay cod were found to be genetically distinguishable from offshore cod (Ruzzante, et al., 2000), confirming that the stock is indeed a local resource. Sonic tagging and tracking experiments conducted from 1996-99 demonstrated that these cod remain in the bay year-round (Green and Wroblewski, 2000). This research is conducted in partnership with Fisheries and Oceans Canada, the provincial Department of Fisheries and Aquaculture, the Labrador Fishermen Union Shrimp Co. and the White Bear Development Association. In response to these findings, the communities of Williams Harbour and Port Hope Simpson asked DFO to consider Gilbert Bay as a marine protected area.  In 2005 Gilbert Bay was announced by the Minister of Fisheries and Oceans Canada as the first Marine Protected Area in eastern Canada's subarctic coastal zone established and managed under the Oceans Act.
