An offshore wind-solar-aquaculture integrated floater is provided, including vertical-axis wind turbine systems, solar photovoltaic panels, and a cube aquaculture cage. Four vertical-axis wind turbine systems are respectively rigidly connected to four corners of the cage; solar photovoltaic panels and a living and working quarter are located on cage deck; and side frames of the cage are equipped with tensile nets, the bottom frame of cage is equipped with a bottom net, and columns of the cage are equipped with lifting rails. This floater has good stability, sea-keeping performance and high strength. Utilizations of offshore wind and solar energy above the cage are high and they complement each other in power generation. This disclosure manages to exploit ocean resources to an unprecedentedly large extent, while resolving the issue of combing power generation with marine aquaculture in moderate and deep seas.

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 steel structure cage for marine crustacean aquaculture and integration thereof into a vertical fish-crustacean aquaculture system are disclosed. The steel structure cage includes a steel frame, top, side and bottom net systems, a ballast tank system, and steel grooves. The steel frame includes internal and external steel frames. The steel grooves are fixed on upper and lower ends of the internal steel frame. Edges of the top and bottom net systems are respectively fixed into the corresponding steel grooves. The side net is welded on the internal steel frame. The ballast tank system is arranged between the internal and external steel frames. A HDPE cage is moored to the steel structure cage to form a vertical aquaculture system. Whereby, an ideal culturing environment for marine crustaceans is given and the objective of vertical aquaculture 'culturing fish at top water layers and culturing prawns (crabs or cowries) at bottom water layers' can be fulfilled.
