All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.

For the first time, early this summer 1999, New Jersey's Reef Program will place 600 designed fish habitats on its ocean artificial reefs. These designed reef habitats, called Reef Balls, were developed and patented by a company in Sarasota, FL. Reef Balls are made of concrete and resemble an igloo with lots of holes. The habitats are 4' in diameter, 3' high and weigh about 1,400 pounds. The many holes around the periphery provide access for fish, crabs, and lobsters to the hollow interior of the undersea homes.
