Alien Invasive Species Management: Stakeholder Perceptions of the Barents Sea King Crab

The alien invasive Red King Crab in the Barents Sea represents both a threat, via ecosystem impacts, and a gain as a revenue source from food sales. Uncertainties exist regarding the ecological impacts but debate in Norway has also emphasised the economic benefits to marginalised fisher communities. This paper reports on a Q-methodology study involving key stakeholders to probe the extent to which divisions exist between different groups. While divisions are indeed found and two groupings identified, these are not as clear as suggested by the lines typically portrayed in the media and elsewhere –, i.e. economic gains versus ecological preservation. Stakeholder groups reported here generally agreed that biodiversity concerns should be central and that further invasion was undesirable due to potential impacts on ecosystem services.
