Description

Oyster shallow sea cultivation method capable of resisting wind waves and shaking and avoiding floating ice

Technical Field

The invention relates to the technical field of shallow sea cultivation, in particular to a method for cultivating oysters in shallow sea, which is resistant to wind, wave and shaking and capable of avoiding floating ice.

Background

The oyster is cultured in the open sea area far away from the sea bank, and the oyster culturing cage in the seawater ceaselessly shakes due to the large wind and wave and the long duration, so that the oysters in the culturing cage and the culturing cage continuously collide with each other, the newly grown shells of the oysters are knocked off or ground flat, the normal growth of the oysters is influenced, and the oysters grow slowly or grow slowly. If oysters are cultured in the shallow sea in the north and are overwintering, floating ice can also appear in some sea areas in the late winter and early spring period, the floating ice often drags the oyster culturing raft and the culturing cage away, serious economic loss is caused to farmers, the floating ice layer is generally avoided by sinking the culturing cage to the depth, but the oyster culturing overwintering must be carried out in a deeper sea area if the oysters cannot collide together and cannot collide with the seabed, and the shallow sea culturing of the oysters is restricted.
