Moriches Reef was originally very small, but has been expanded greatly. The pink region is the historical area, and the blue region is the new deployment zone, while the full permitted size of the reef is a 1-nm square that encloses the deployment zone. The misalignment in the northern boundary between old and new is accurate.
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.
M60 tanks undergo a thorough cleaning before use as reefs
The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.
Commercial fishing in New Jersey is centered around several small ports, each of which has a particular type of processing or handling facility. Without the necessary facilities onshore, the boats would have no place to take their catch. Belford, in Raritan Bay, supports a fleet of long-liners and seiners with a fish processing plant. Point Pleasant is the locus for shellfisheries and supports a large fleet of resident and transient clam dredges. Barnegat Light has mainly long-line fishing boats and scallopers, while Atlantic City and Cape May have more clammers and trawlers. Lobster boats and head boats are found all over.
