Delaware Artificial Reefs

Delaware Artificial Reefs (and a few New Jersey reefs)

Coverage of Delaware is restricted to just those sites that are in the ocean and vessels in the bay. Siting reefs has been tricky for Delaware, as they must be kept clear of the shipping lanes. This doesn't leave a lot of places that are both located in usefully deep water and a convenient distance from shore. Cape May Reef belongs to New Jersey, but is within range of Delaware, and lately seems to have received material from Delaware. I have also included the USS Blenny, to the south - drag the chart.

Delaware Artificial Reef Sites

Delaware has eight permitted reefs in the Delaware Bay, and another way offshore that is undeveloped and will likely stay that way.

Site #8 has a 70' tugboat "Golden Eagle". Site #6 has a 120' barge. Site #1 has a 40' pilot boat. Other than that, the Delaware Bay reefs are all concrete rubble.

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.



Horned Salp

Thalia democratica

Although they may superficially resemble swimming siphonophores, salps are actually free-living tunicates. There are 6 genera of salps and all are transparent.

Tunicates are much more advanced in the evolutionary scheme of things than jellyfishes, having, for example, a circulatory system. The larvae actually even have several features in common with vertebrates, including the precursor of a spinal cord, but these are lost in the sac-like adults. Salps do not sting.
