The article develops a dynamic model of habitat--fishery linkage in which the habitat is being converted. The basic model is applied to a case study of the impacts of mangrove deforestation on the artisanal marine demersal and shellfish fisheries in Thailand. The comparative static effects of a change in mangrove area on the long-run equilibrium level of effort and fish stocks, as well as on the resulting market harvesting supply of the fishery, are determined. By estimating parameters through pooled time-series and cross-sectional data over the 1983--96 period for the five coastal zones along the Gulf of Thailand and Andaman Sea, the welfare impacts of mangrove deforestation are estimated. Mangrove conversion is expected to be a function of the return to shrimp farming and the input costs to farming shrimp, plus exogenous economic factors. The resulting aggregate reduced-form level of mangrove clearing by all farmers in coastal areas is empirically estimated across the five coastal zones in Thailand over 1983--96. The policy implications of the findings are discussed with respect to Thailand and the modeling of habitat--fishery linkages. Copyright 2003, Oxford University Press.
