A device comprising a corkscrew; a substantially flexible shaft operably attached to the corkscrew at a first end of the shaft; and one or more protrusions extending from the shaft between the first end of the shaft and a second end of the shaft. Methods of using the device are also disclosed.

A double pipe cultivation system which enables the reduction of falling the mussels cultivated with the effect of vertical and horizontal forces that would occur due to wind, wave and tides that can be received in all directions in mussel farms established in sea and lake areas, and the losses that can occur due to similar reasons.

A system of fattening for molluscs having supporting frames with first coupling members for the uprights that make up components and, carriers of the breeding compartments, and second coupling members on the flotation tubes of a moveable platform. The members and the uprights have aligned openings and that are actuated by removable coupling devices allowing the uprights to be attached or uncoupled. A crossbar, with an arrangement of connectors, keeps the components and provides an easily handled module that can be separated from the supporting frame along with the breeding compartments.

An automated oyster maturation system including a containment assembly rotatably disposed within a housing. The containment assembly includes a spiral construction that includes compartments that are in communication with one another, walls that define the compartments, and ramps. Openings disposed in the walls and ramps increase in size from the outer diameter to the inner diameter of the spiral construction so that, with every complete rotation of the containment assembly, every oyster will tumble further into the spiral construction and ascend from its original compartment into the adjacent inner compartment where opening size is larger than in the original compartment such that only oysters which have grown sufficiently can remain in the adjacent inner compartment while oysters that have not grown sufficiently yet will fall through the openings of the adjacent inner compartment into the original compartment.

A coral reef float utilizes a large, elongated steel and, optimally, balloon shaped structures which can be prefabricated en masse, anchored in place to rest buoyant below the ocean surface, and then used to farm live coral. These large structures using biorock applications have insulated copper cables attached at multiple points every 5-10 feet along the structure for homogenous corrosion resistance and mineral accretion on the surface of the structure. A hollow, balloon shaped structure allows more of this copper wiring to be connected internally, where it can be protected from corrosion. Helical anchors can be used in soft sediments and to handle extreme conditions for tethered floats using easy-to-deploy systems onboard ships. Buoyant artificial reefs will be able to be positioned where other artificial reefs cannot effectively be placed.
