Valuing Coastal Habitat–Fishery Linkages under Regulated Open Access
AbstractThis paper explores how regulation of an open access fishery influences the value of a coastal habitat that serves as breeding and nursery grounds. A model of the fishery supported by a coastal wetland is developed, which includes a quota rule that restricts harvest to a fixed proportion of the current stock. The model is applied to mangrove-dependent shellfish and demersal fisheries in Thailand. The value of the welfare effects associated with a change in a supporting coastal habitat is influenced significantly by whether or not the regulatory quota can adjust in response to these changes. Welfare losses are considerably higher when the quota is fixed as opposed to when it can be adjusted. With the restriction in place, effort cannot change to offset the decline in biomass, and as a result, there is a much larger fall in harvest. In addition, the welfare losses are much larger for the shellfish compared to the demersal fisheries. The analysis illustrates that imposing a regulatory rule on an open access fishery has important implications for valuing any linkage between coastal breeding and nursery habitat and a near-shore fishery.
