اجرای بهینه طراحی و تامین مالی برای صنایع گردشگری ماهیگیری در مقیاس کوچک و شیرجه رفتن

Effective enforcement can reduce the impacts of illegal, unregulated, and unreported (IUU) fishing, resulting in numerous economic, ecological, and social benefits. However, resource managers in small-scale fisheries often lack the expertise and financial resources required to design and implement an effective enforcement system. Here, a bio-economic model is developed to investigate optimal levels of fishery enforcement and financing mechanisms available to recover costs of enforcement. The model is parameterized to represent a small-scale Caribbean lobster fishery, and optimal fishery enforcement levels for three different stakeholder archetypes are considered: (1) a fishing industry only; (2) a dive tourism industry only; and (3) fishing and dive tourism industries. For the illustrative small-scale fishery presented, the optimal level of fishery enforcement decreases with increasing levels of biomass, and is higher when a dive tourism industry is present. Results also indicate that costs of fisheries enforcement can be recovered through a suite of financing mechanisms. However, the timescale over which financing becomes sustainable will depend largely on the current status of the fishery resource. This study may serve as a framework that can be used by resource managers to help design and finance economically optimal fisheries enforcement systems.
