Abstract
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.
