A floating offshore wind turbine integrated with a steel fish farming cage mainly includes a wind turbine, a wind turbine tower, a living quarter, a floating wind turbine foundation in a conic steel structure, a mooring system, a lateral net encircling the floating wind turbine foundation, a bottom net, and lifting systems. The upper end of the wind turbine tower hosts a wind turbine, and the lower end of the wind turbine tower is fixed on the floating wind turbine foundation. In the present invention, the inner space of the floating wind turbine foundation is used to form a huge farming cage, which functions for the objectives of power exploitation on the top and fish farming at the bottom. The foundation has excellent stability and seakeeping performance, and is applicable to deep waters.

A floating Fishermen's island for growing 10,000 tons of fish and seafood within multiple water-filled ring-tube fishery, including auxiliary fish growing pools and recreation boating, fishing and water sports amenities. The Island comprising equally spaced radial Island member array made of molded plastic emerging from a floating Island center with cylindrical ends pivoted to island center arms-ends and to island outer boat docking segments. Vertical poles extending island radial members supporting walk-over-water fishermen's deck segments above water-filled ring-tube fishery for fishing from fish pools underneath. Connection cable connects each island radial member underneath the ring-tubes, with cable to anchor the island to seabed. A walk over water elevated deck connected with bridges over poles multiple radial island docking for large service boats, sail boats and speed boats comprising multiple radial island boat docking segments, service boat docking segments allow loading and unloading reef for multiple service, sail and motorboats.

A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.

An aquaculture system including a negatively buoyant enclosure disposed within a body of water. A mooring line can extend between a first anchor and a second anchor coupled to a bottom surface of the body of water, respectively. Two buoys can be disposed within the body of water and on opposing sides of the enclosure and the mooring line can extend from a first buoy and a second buoy and back to the bottom surface of the body of water. The mooring line can be coupled to a bottom surface of the enclosure between the first buoy and the second buoy.
