摘要

Rights-based management has been advocated as a means of improving the biological sustainability and economic performance of commercial fisheries. The most common forms of rights-based management implemented are individual transferable catch quotas (ITQs) and individual transferable effort quotas (ITEs). Perceptions of success of these management systems vary, however, with some being considered successful while others have been criticized, especially when broad social outcomes are taken into consideration. In this study, we develop a Bayesian belief network model that considers the underlying governance and social environment in which the fishery operates, along with the characteristics of the fishery. We use data derived from a survey of fishers, managers, and scientists to populate the model from 47 Australian fisheries currently managed through ITQs and ITEs. As well as capturing the characteristics of the fisheries, the survey asked respondents for their perceptions on the overall performance of the management system, as well as its performance against social, economic, environmental, and governance objectives. The results suggest that positive perceptions of management performance are related to the quality of social relationships between fishers, the efficiency in the functioning of quota markets, and the degree to which economic information is used in quota setting.
