Potential impacts of artificial reef development on sea turtle conservation in Florida

Abstract

Artificial reefs have been constructed and deployed worldwide to enhance marine habitat, primarily to increase socio-economic benefits stemming from associated fishing and diving activities, but also for habitat restoration and mitigation purposes. As a result, the majority of studies focused on artificial reefs to date have centered on measuring performance, with metrics such as species' richness and abundance compared to natural reefs, or economic benefits to local users. While there may be demonstrable benefits to artificial reef development, there may also be unforeseen consequences. This study investigates the impacts Florida artificial reefs may have on sea turtle populations, such as increased predation stemming from altered predator complexes, mortality due to entrapment, and entanglement issues. Based on some of the associated effects artificial reef development may have on sea turtles, management recommendations to minimize potential impacts are offered for consideration.
