What is an Oyster Castle

• Manufactured concrete block designed to be
  instant habitat for oyster spat and oyster growth
  once deployed in an area designated with
  potential due to the availability of juvenile
  oyster spat.
• They are a 12 square block, 8 high, with
  certain features that enable them to be stackable
  and interlocking. The stackable and interlocking
  nature of the blocks lend themselves to the
  stability and wave resistance of the assembly and
  installation.
• These block are currently being used successfully
  on the Eastern Shore of Virginia, and will be
  marketed to Restoration groups and agencies in
  coastal states/regions of the eastern United
  States.
• Oyster Castles are manufactured on a conventional
  concrete block(CMU) machine in standard molds
  with special raw materials.
