Migrations and harvest rates of Arctic charr (Salvelinus alpinus) in a marine protected area
ABSTRACT Arctic charr are a particularly important species in Arctic and sub‐Arctic regions and face conservation challenges including human exploitation. Arctic charr migration pattern and harvest rate in the Gilbert Bay Marine Protected Area in southern Labrador, Canada were examined. The marine m...
