Neoliberal thought has exerted significant influence over the crafting and delivery of environmental policy. This has manifested in enlisting non-state actors to advance environmental policy agendas in ways that were previously the responsibility of the state. The participation of these non-state actors is positioned as integral to solving intractable environmental challenges, such as the degradation of fish habitat. Drawing on responsibilisation as a technique of governance, this research adopts a case-based study of fisheries rehabilitation policy to explore how recreationists are being mobilized to address environmental problems. Deploying interpretive policy analysis to analyze key policy artifacts this research highlights how fishers as recreational users of aquatic areas are constituted as moral, political and authoritative actors who bear responsibility for ameliorating degraded fish habitats, despite the impacts of recreational fishing on these habitats being contested. We conclude by identifying the implications of this responsibilisation for the implementation of co-management and shared stewardship of fisheries resources.
