480:. A recovery team for the northern and spotted wolffish has almost completed a recovery strategy and plan for both species. The strategy provides a framework for improving the status of wolffish through an enhanced understanding of their life history, potential sources of harm, and implementing management measures such as live release of captured wolffish. The plan also includes habitat stewardship and educational activities designed to involve stakeholders and inform the public.
