ABSTRACT:
An artificial reef of lightweight construction employs a dome-shaped, thin-walled enclosure of plastic material having apertures therein to permit acquatic life to enter and exit. The enclosure has a circular perimeter that is provided with a circumferential trough integrally formed with the enclosure. At a staging area adjacent the installation site, concrete ballast is poured into the trough to form a perimetrical weight which holds the reef in position on the desired underwater surface. The construction allows the reef to be installed from the surface of the water by releasing it over the site and permitting it to parachute downwardly through the water until it comes to rest.
