Development of a Submersible Raft for Shellfish Aquaculture

We propose the development of a full-scale, unique, mussel producing aquaculture platform that can remain fully submerged for the entire benthic stage of the mussel growth cycle. Our experimental mussel growing concept is unique in that it is designed to be fully submersible, unlike conventional surface mussel rafts currently being used that are subject to the ravages of wind, heavy seas, and ice flows, among other disadvantages. Our apparatus remains well below hazards on the surface. Our proposed raft stays submerged at the 10 to 15 foot level and is only brought to the surface for occasional services, or to harvest mature, marketable mussels. We are striving to create technology that is logistically, environmentally and economically feasible, which will help to reduce multiple-use conflicts, and which will lead to economic opportunity in the aquaculture sector.
