Abstract
  • Western Australia operates a diverse enforcement and education program aimed at achieving high compliance in a wide range of commercial and recreational fisheries managed using a mix of input and output controls. Since enforcement resources are invariably insufficient to totally eliminate non-compliance with fishery rules, it is important to ensure that they are optimally allocated toward those areas or activities that pose the greatest compliance risks. While it is generally accepted that compliance with fishery rules by participants is fundamental to the success of any fisheries management plan, most management agencies collect very little data to enable estimates of non-compliance or take of illegal catch. The reasons for this are twofold: compliance information is notoriously difficult to accurately measure, and enforcement personnel often do not have the training or experience to design surveys or experiments. In this paper I explore the concepts of statistical sampling principles, experimental manipulation of enforcement effort, and adaptive management as tools for helping to target enforcement resources for best effect. The role of experimental design and statistics for the collection and analysis of fisheries biological and ecological data is well established. Western Australia has adopted the approach that collecting compliance related information should be undertaken with the same rigor as any of our biological sampling programs. To this end, fisheries officers routinely collect location-, activity-, and fishery specific contact and infringement information. Analyses of these data help to direct future enforcement activity to specific areas of fisheries where compliance risks appear evident. Officers also take part in large-scale manipulative experiments varying the level of their enforcement activities. I outline the approach to compliance data collection and analysis adopted in Western Australia, drawing on examples of work undertaken in the western rock lobster fishery.
