tFishery management is increasingly moving toward management that accounts for environmental andsocial dimensions. Such an approach requires the integration of natural and social science informationinto planning and decision-making processes. The actual integration of social science information, how-ever, remains limited in many policy and decision-making processes within fisheries. Our study providesinsights into factors that influence the intention to use social science information among fishery managersand the actual integration of such information into fishery management. Based on interviews with fish-ery managers in the Great Lakes, we find that the lack of social science expertise in fishery managementagencies leads to multiple negative beliefs and attitudes, and subsequently a low intention to use socialscience information in decision-making processes. At the same time, the paper finds that more expertisein decision-making tools and basing social science on equal footing with natural sciences within fisherymanagement institutions appears critical to advance the actual integration of social science informationin fishery management.
