Reportages - Creating a Reef (119) Images supplémentaires...
Artificial reefs are man-made structures that are either deliberately or unintentionally submerged underwater, commonly with the result of mimicking some characteristics of a natural reef.
They may be created from a variety of sources and materials including the intentional sinking of ships and barges, concrete structures, tyres and other materials.The intentional deployment of artificial reefs enhances the production of reef associated species and mitigates against losses from overfishing, pollution and habitat destruction.
