s -1, while showing best growth conditions of the cultured oysters as well as for the spat settlement of juvenile greenshell™ mussels.

Initial results show that the new design has survived waves at 4.6 m significant height and current velocities of up to 0.7 m The modelled structure indicates a design tolerance of significant wave height of over 7 m and currents of over 0.8 m/s. The system was deployed in March 2019 six nautical miles off the Bay of Plenty, North Island (New Zealand), in exposed waters near a commercial mussel farm and has been in test mode since then. The operational depth of the whole system can be at any depth but was tested at between 5 and 10 m below the water surface positioned on the mooring line between the screw anchor and surface floats for the prototype tests. Other possible candidates could be seaweed, lobsters, sponges or tunicates. These sub-units can be used for the culture of oysters ( Magallana gigas – formally Crassostrea gigas) as well as for the collection of mussel spat ( Perna canaliculus).

The final structure has a hexagonal body, with a centrally orientated variable buoyancy unit with culture sub-units on each of the six corners. These included multiple iterations during the designing stage, wave tank testing, fabrication, loading and unloading on trucks and vessels, deployment at sea, installation and assembly on the single mooring line, and bring it to its final position in a submerged mode 5m-10 m below the water surface. Marine Culture at the Virginia Institute of Marine Science over the past seven years has developed an oyster hatchery system through research. The device has gone through several very different phases of development on its way to the deployment of the prototype. The technical feasibility of the new construction, called Shellfish Tower, was assessed. Pricing listed below is for orders of 10,000 pieces or more.
