Fisheries management has evolved over the centuries as marine resources have been discovered and harvested. Recently there has been increased focus placed on a more holistic approach to management as fisheries adopt an ecosystem approach to management (ecosystem based fisheries management) which implicitly includes both an increased understanding of the effects of fishing on the ecosystem as well as the involvement of the human system. Despite this focus, most fisheries remain managed as single species entities based around a range of management tools and harvest strategies aimed at sustainable production. While many of the management tools (e.g. size limits, closed areas, catch limits) can be applied to range shifting species, we argue that transformational change in our thinking is required as range shifting species appear and establish in their “new” ecosystems.
