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.

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.
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 ]
“Measures to increase fish resources like setting up artificial coral reefs can help avoid this competition and also indirectly help protect turtles.” Multiple studies by climate scientists have found that the risks of more intense, unpredictable and frequent cyclones have increased along India's coastline as a result of global warming.
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.
Oyster Reef. Oyster reef restoration refers to the reparation and reconstruction of degraded oyster reefs.Environmental changes, modern fishing practices, [1] over harvesting, [2] water pollution, and other factors, have resulted in damage, disease, and ultimately, a large decline in global population and prevalence of oyster habitats.
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
