Artificial Reefs

What are Artificial Reefs?

An artificial reef is a human-made underwater structure that substitutes as a natural reef to form a habitat for marine life. Artificial reefs are placed in areas where there is little bottom topography or near coral reefs to attract marine populations. These structures are made from a variety of materials including shipwrecks, construction debris, oil rigs, concrete, and any other man-made material.[1]

Why Artificial Reefs?

Artificial reefs serve to protect coral reefs form human-induced damages. In addition, they are used for mitigating coastal erosion, creating surf breaks, and in the past have been built to block ships from entering coastal waters. These structures create plankton-rich feeding spots that attract small animals and the reef soon becomes covered by encrusting coral and sponges. The collection of smaller marine organisms brings in predators and expands to establish a new habitat. The significance of this is that these spots divert reef-dwellers like divers and boaters from endangered coral reefs to the artificial reef.[2][3]

Fisheries Management

  • biodiversity
  • sustainability of fish populations
  • special features of artificial reefs in solving fisheries management problems[4]

Types of Artificial Reefs

  • Basic characteristics and requirements, must be heavy, non-toxic, etc.[5][6][7]

Manufactured

  • EMA
  • reef balls and fish condos
  • mass produced concrete structures (e.g. cinder blocks)

Recycled

  • extensive cleaning and prep required
  • public transit
  • retired ships
  • retired tanks and military equipment
  • tires

Additional Types of Artificial Reefs

  • Art and sculpture reefs - Silent Evolution in Cancun
  • Memorial reefs - Neptune Reef - Ashes from cremation formed into artificial reef bases
  • Surfing reefs - Cables, Perth, Australia[8]


How Do Artificial Reefs Stack Up with Natural Reefs?

  • Note inconclusiveness and need for additional studies[9]

Advantages of Artificial

  • Can be placed in convenient and easily accessible locations[10]
  • Cheap recycled materials[11]
  • Can be calibrated specifically for their environment and specific organisms[12][13]
  • long term profit for tourism
  • Rapid colonization, high fish densities, and high catch rates[14][15]

Disadvantages of Artificial

  • Expensive transportation and labor
  • Recycled materials need extensive cleaning and stripping[16]
  • Possible introduction of toxins
  • large initial investment
  • Suggested that only 50 percent of artificial reefs meet their established goals[17][18]
  • Heavily exploited areas need significantly more help than just adding reef structures[19]

Eco-tourism and Artificial Reefs

  • New dive sites lead to new economic opportunities
  • Cheap option for developing tropical countries to attract tourists
  • Long term profit
  • Increased and easily located fish populations attract tourists interested in fishing[20]
  • Tourists attracted to reef destinations create a demand for hotels, restaurants, and other markets associated with tourists
  • All of the above while helping the oceans and increasing fish populations!
