A conventional artificial reef uses materials such as concrete, which can be molded into specialized forms (e.g. reef balls). Green artificial reefs incorporate renewable and organic materials such as vegetable fibres and seashells to improve sustainability and reduce energy consumption, pollution, and greenhouse gas emissions.

In 2004, 12% of the continental shelf of Japan held twenty million cubic metres of artificial reefs of all types particularly metal structures. [1] Concrete blocks are frequently used but also metal towers 35 metres high weighing 92 tons mounted on three discs each three metres in diameter which create walls with currents to block plankton.

Rigs-to-Reefs (RTR) is the practice of converting decommissioned offshore oil and petroleum rigs into artificial reefs. [1] Such biotic reefs have been created from oil rigs in the United States, Brunei and Malaysia . [ 2 ]
Its aim is to create environmentally and economically sustainable artificial reefs (ARs) in British Columbia and around the world for the protection and enhancement of sensitive marine habitats, while also providing interesting destinations for the enjoyment of scuba divers. The Society operates without any paid employees.
National Fishing Enhancement Act of 1984; Other short titles: Antarctic Marine Living Resources Convention Act of 1984: Long title: A bill to establish national standards for the construction and siting of artificial reefs in the waters of the United States in order to enhance fishery resources and fishing opportunities and for other purposes.
Their printers are made to work anywhere, from coastal reefs to Alaska. Penn State researchers created 3D-printed housing for life on Mars. Next: artificial reefs
Over time the artificial reef becomes covered by epifaunal organisms such as oysters, musselss, barnacles, tunicates, sponges, and corals. This increases small-scale changes in the surface relief of the structure which provides habitat for crabs , worms , sea urchins , blennies , and other animals.
The Louisiana Artificial Reef Program (ARP) was established in 1986 to create habitats for providing food, and shelter for marine life that includes coastal fish, using human-made structures. The program includes several types of artificial reefs that supports ecosystem development, recreational fishing and diving, and critical research.
