History of Artificial Reefs and Materials
Since the first ships and sailors, we have known that objects placed in sea water are soon colonized with marine life. Beyond the initial nuisance of growing barnacles and infestations of aquatic wood boring worms on wooden ship hulls, mariners observed large fish populations inhabiting sunken vessels.
From these early observations, the first artificial reefs were constructed from manmade materials purposefully put underwater to enrich marine life. New reefs were mainly constructed from deteriorating vessels or “materials of opportunity”. In the 1830s, artificial reef pioneers in South Carolina experimented with logs huts, which they discovered deteriorated too quickly. Locally, as early as the 1950s and 60s, fishermen used railroad cars, school buses, car bodies, white goods (stoves, refrigerator, washer, etc.), tires, and even porcelain toilets.
Modern use of Artificial Reefs and Materials
Today’s artificial reef materials have moved from underwater junk yards to marine resources that will last at least 20 years and not harm wildlife or the environment. Decommissioned steel hulled ships and durable “materials or opportunity” are still utilized. Additionally, new engineered concrete artificial reef modules that support specific species and various life stages of fish have been developed. Current fisheries research seeks to refine materials, design, and placement of artificial reefs to maximize conservation.
Within hours of sinking a vessel or artificial reef, baitfish move into their new home. This initiates a “parade” of marine life over several months. The hard structure of an artificial reef is slowly colonized by soft corals, plants, and barnacles. Baitfish will soon have new neighbors, as snapper and grouper take residence. Nearby sand sediments come to life with sea stars, sand dollars, and other invertebrate species. In total, it takes about 3 – 5 years for reefs to reach a level of maximum production for both fish and invertebrate species.
Attraction vs. Production
Almost as old as the history of artificial reefs is the question of attraction vs. production. Do artificial reefs actually increase the fish population or merely increase the number of fish being caught? Researchers struggled with this question for decades producing seemingly conflicting results. Today’s consensus is that the answer to the question is both yes and no – it depends. When fishing pressure and mortality exceed the number of fish produced, artificial reefs can end up as expensive fishing equipment. It’s in everyone’s interest to avoid this situation create productive resources.
Fisheries Management Tools
Artificial reefs are best used as a fisheries conservation tool that disperses fishing pressure and promotes healthy fish stocks. The ultimate goal when using artificial reefs is for fish production to exceed any fishing or natural mortality. Artificial reef managers or charterfishing captains deploy variety of reef materials that support fish at varies sizes and ages. Reefs are deployed so that the exposure to fishing pressure is limited by time or by geographic location.
How to Permit an Artificial Reef for Deployment in Local Waters
Bay County has two Large Area Artificial Reef Sites or LAARS, open to public permit and deployment. Permits are only $30.00 details and instructions are available at http://x.co/bayreef
Economic Benefits of Artificial Reefs
Our artificial reefs support more than just fish they support people and jobs that earning a living from Bay County important artificial reefs and fishing are to Bay County. A more recent study estimates, for every $1 spent on artificial reefs in the Florida Panhandle, the economic benefit of artificial reef expenditures returns $138.
Ready to go fishing? A list of reefs can be found on our artificial reef page. This page has an interactive map with weblinks to individual reef sites where we are collecting your submitted pictures and video. We are currently verifying and updating the coordinates to Digital GPS. Additional Reefs will be deployed in 2012 using construction grant funds from Florida Fish and Wildlife Commission. The County has also proposed new reef sites about two miles off the County Pier and Panama City Beach Pier (Pier Park). Bay County and other local governments have requested over 2 million dollars in funding as a part of early projects for National Resource Damage Assessment (NRDA).

The Extension Artificial Reef Advisory Committee and the Planning Department has great expectations for the Bay County artificial reef program in 2012. We have received local support with logistics, materials of opportunity, funding, education and promotion. We appreciate and welcome the contributions of charterfishing/diving industry, tourists, and residents. For more information about artificial reefs, contact Scott Jackson at the Bay County Extension Office at 850-784-6105. All programs are open to all persons regardless of race, color, age, sex, handicap or national origin.
