Florida coastal waters contain more permitted artificial fishing reef sites (ca. 150) than any other state. Initiative stems primarily from local interests, including over 60 different private and public organizations. Florida's earliest reef was authorized in 1936 although 87% were proposed after 1962. Prevalent reef materials include some combination of concrete rubble, tires, automobiles and/ or vessels in 40% of Florida reefs, followed by vessels (25%), and automobile bodies and tires (13% each). Statewide resource agencies and educational organizations have fostered local reef building through financial assistance with construction, streamlined permitting procedures, information transfer via advisory services for siting and publications, and coordination of research, which has yet to address the economic impact of recreational reef fisheries.
