Are Marine Protected Areas in the Turks and Caicos Islands ecologically or economically valuable?

Marine Protected Areas (MPAs) are often advocated by ecologists as a method of conserving valuable fish stocks while ensuring the integrity of ecological processes in the face of increasing anthropogenic disturbance. In the Turks and Caicos Islands there is little evidence that current MPAs are ecologically beneficial but there are indications that boundary changes may enhance queen conch and finfish production. Implementing boundary changes usually requires political will and, hence, quantifiable economic benefits. Assessing the value of reef fish is particularly important because they are potentially valuable for consumptive and nonconsumptive purposes. We demonstrate the nonconsumptive economic value of increased Nassau grouper size and abundance to the dive tourism industry through a paired comparison conjoint survey of visiting divers. Our results suggest that accounting for the non-consumptive economic value of increased Nassau grouper abundance and size may have a large impact on the economic viability of ecologically functional MPAs.
