Spatio‐temporal trends of the Krill fisheries in the Western Antarctic Peninsula and Southern Scotia Arc
Abstract Krill fisheries in Antarctica have concentrated their effort on the Western Antarctic Peninsula and Scotia Arc (WAP) in the last decades, following a steady increase in annual catch. Short‐term shifts in habitat exploration may have occurred and may be the cause for the increasing catch. Ha...
