Fisheries co-management is an arrangement in which responsibilities and obligations for sustainable fisheries management are negotiated, shared and delegated between government, fishers, and other interest groups and stakeholders. This is the definition of fisheries co-management developed by the Fisheries Research and Development Corporation’s national working group on the fisheries co-management initiative. It reflects the increasing recognition among fishers and fisheries managers alike of the need for a cultural change, away from an untrusting, often conflicted “them versus us” approach to one of partnership based on joint responsibility for decision-making and implementation in fisheries management.  This definition also encompasses the key factor of delegation of functions to fishers, which many other co-management models do not envisage.
