How Property Rights Can Spur Artificial Reefs

Artificial Reefs Enhance the Marine Environment and Benefit Environmentalists and Recreationists

FEBRUARY 01, 1997 by MICHAEL DE ALESSI

Mr. De Alessi is coordinator of the Center for Private Conservation, a project of the Competitive Enterprise Institute in Washington, D.C.

Small fishing communities knew what they were doing when they created the first artificial reefs out of rocks and logs hundreds of years ago. When large, heavy objects are dropped into the sea, they attract and propagate large numbers of fish. In Japan, traditional fishing communities have evolved into cooperatives that own the reefs outright, and this secure ownership is the reason why their reefs are well-protected, productive resources.

Unfortunately, private rights to the seabed are virtually nonexistent in the United States.[1] Artificial reef creation has generally been the province of state conservation departments since the 1950s. These departments have made artificial reefs offshore out of everything from old tires, coal ash blocks, and automobiles to decommissioned ships and oil rigs. Often, this is at the behest of private sports fishing or diving interests.

But in one state, Alabama, artificial reefs can be privately owned—sort of. Private citizens are allowed to create artificial reefs. The state provides no defense of this ownership, however. If others learn about the reef, they can use it, too, so the property right is marginal at best. Even so, the most tenuous private property right related to reefs—simply having proprietary information on the exact location of a reef—results in a tremendous private initiative to create such reefs.

Artificial reefs are popular with local recreationists and environmentalists because they enhance the marine environment. Within days of a hard substrate appearing on the seafloor, small encrusting animals begin to attach themselves, in the process creating more surface area for other organisms to either attach to or hide behind. Thus artificial reefs create habitat for many species of both fish and invertebrates, which in turn attract many larger fish, some of which might not survive otherwise. There is some debate over the extent to which reefs attract sea life that is already present and the extent to which they encourage propagation of more fish and other animals. Clearly, they do both.

The Gulf of Mexico is particularly well suited to artificial reef creation because its seafloor lacks the rocky bottom and outcroppings that can support a rich variety of life (although even California, which has such features, has a strong contingent clamoring for artificial reef production). Dropping one of these [artificial reefs] in the middle of this vast expanse of mud bottom is like putting an oasis in the desert,[2] says an official with the Texas Parks and Wildlife Department.

Sunk Assets

Many of the privately created reefs off the coast of Alabama were formed by sinking old autos. While this may not initially seem prudent, the cars are well cleaned of any noxious chemicals before they are carried out to sea. Even without stringent regulations, many of the people who fish around these reefs eat what they catch, so it is also in their best interests to keep fish free from toxic chemicals. The main problem with cars is that they do not last very long, but without secure private property rights, there is little interest in finding more durable materials.

Legal, private reef creation began in Alabama in 1987 when the Department of Conservation and Natural Resources created the first of two large areas where people are allowed to sink acceptable objects (those passing a state inspection to ensure that no toxic materials remain). The measure came in response to the artificial reef creation that was already going on illegally. Recreational fishers had figured out the benefits of small artificial reefs and had been sinking objects on their own for many years. Eventually the commercial fishing industry grew tired of stray shopping carts damaging their nets, so they convinced the state to take action.

Because the jurisdiction over artificial reef creation rested with the U.S. Army Corps of Engineers, Alabama arranged for a large permit from the Corps, then issued its own permits to the public. As part of this arrangement, the state assumed all of the liability resulting from these reefs, which encouraged their creation but discouraged any private interest in the long-term effects of the reefs. Strengthening ownership rights to artificial reefs and returning liability to their owners would encourage long-term care and stewardship.

Once reef creation was sanctioned by the state, the numbers of reefs took off, and so did entrepreneurial activity. One company has specialized in preparing old cars to meet state standards, then delivering them to a specified and confidential location. Since 1987 it is estimated to have placed over 5,000 cars and 300 school buses underwater.[3] As a result of this kind of activity, in 1992, with only a fraction of the Gulf Coast shoreline, the recreational catch of red snapper in Alabama was two to five times higher than those of the other Gulf states.[4]

The value of proprietary information encouraged reef creation, but the fleeting nature of the property right and lack of liability encouraged people to consider only the short-term benefits of their actions. Thus most of the reefs were formed from old washing machines, toilets, and all sorts of other junk that corroded quickly or was otherwise rapidly destroyed. Auto bodies lasted longer, usually five years or more, but when Hurricane Opal passed by Alabama in 1995, many reefs were washed out of the area or destroyed, and auto hoods started winding up in fishing nets. This led the state to institute a moratorium on most junk and scrap by early 1997. With this move, Alabama may see some of its sport fishing moving to Florida.

Strengthening Property Rights

Setting restrictions to solve this problem ignores the very reason why care was not taken to avoid storm damages in the first place. Cars made popular reefs because they lasted longer than one could hope to keep a good fishing spot secret. For only slightly more than a car,[5] a firm called Reef Ball Ltd. offers prefabricated artificial reefs, specifically designed to enhance the marine environment and to be durable. By strengthening private property rights to artificial reefs, owners would naturally take an interest in their protection, and would probably be more interested in Reef Balls than old Chryslers. Increased liability would also encourage owners to account for the long-term effects of reef placement and construction.

In Japan, where the rights to subtidal lands are clearly defined, the level of investment in artificial reefs is huge. Custom reefs are designed for specific habitats and species production. Many fishing cooperatives even place guards to watch over productive areas day and night.[6] Japan is hardly a perfect example,[7] yet the vigilance with which private reefs are protected, and the research efforts that go into fishing reefs demonstrate the vast potential for the positive benefits of private ownership.

The success of Alabama’s artificial reef program is having an effect outside the state—Florida recently started creating large permit areas, and other Gulf states may follow suit. Limited ownership schemes already exist in offshore waters for aquaculture and oil and gas exploration. Extending those leases to artificial reefs would be a simple step toward encouraging the kind of private stewardship of artificial reefs that has been so successful in Japan.

7. Fishing cooperatives in Japan are heavily subsidized by the government, which also dictates that artificial reefs must be prefabricated. Thus one of the most important organizations involved in reef creation in Japan is the industry group of cement manufacturers, construction firms, steelmakers, and manufacturers of plastic materials.

CURRENT ISSUE

July/August 2014

The United States' corporate tax burden is the highest in the world, but innovators will always find a way to duck away from Uncle Sam's reach. Doug Bandow explains how those with the means are renouncing their citizenship in increasing numbers, while J. Dayne Girard describes the innovative use of freeports to shield wealth from the myriad taxes and duties imposed on it as it moves around the world. Of course the politicians brand all of these people unpatriotic, hoping you won't think too hard about the difference between the usual crony-capitalist suspects and the global creative elite that have done so much to improve our lives. In a special tech section, Joseph Diedrich, Thomas Bogle, and Matthew McCaffrey look at various ways these innovators add value to our lives--even in ways they probably never expected.
