Oyster shallow-sea breeding method resistant to waggling caused by wind waves and capable of avoiding floating ice

Abstract

The invention provides an oyster shallow-sea breeding method resistant to waggling caused by wind waves and capable of avoiding floating ice. According to the technical scheme, an oyster shallow-sea usual breeding device is involved, the two ends of a large rope (8) are fixedly connected with hanging rings (3), the large rope (8) penetrates into connecting rings (9) and is knotted to evenly fix the connecting rings (9), hanging ropes penetrate into the connecting rings (9) and are knotted to fix the connecting rings (9), the upper ends of the hanging ropes are fixedly connected with floating balls (2), the floating balls (2) float on a sea surface (1), and the lower ends of the hanging ropes penetrate into cylindrical holes (19) of breeding barrels (6), the tail ends of the hanging ropes are knotted to fix the breeding barrels (6), and the hanging rings (3) at both ends of the large rope (8) are connected with two pile ropes (4) respectively. The method has the advantages that oyster breeding can be implemented in sea areas under different sea conditions, and the normal growth of oysters is ensured; a broad offshore sea area space is expanded for oyster breeding, and the sustainable development of marine environment protection and aquaculture is achieved.

Description

technical field [0001] The invention relates to the technical field of shallow sea culture, in particular to a shallow sea culture method for oysters that is resistant to wind and wave shaking and can avoid floating ice. Background technique [0002] Oysters are cultured in the open sea far from the coast. Due to the strong wind and waves and the long duration, the oyster culture cages in the seawater are constantly shaking, so that the oysters in the culture cages and the culture cages are constantly rubbing against each other, resulting in the newly grown shells of the oysters. If it is knocked off or ground flat, it will affect the normal growth of oysters, and the oysters will not grow or grow slowly. If the oysters are cultured in the northern shallow sea, they have to go through the winter, and there will be ice floes in some sea areas in the late winter and early spring. Sink the depth of the breeding cage to avoid the floating ice layer, but because the breeding cag...

[0002] Oysters are cultured in the open sea far from the coast. Due to the strong wind and waves and the long duration, the oyster culture cages in the seawater are constantly shaking, so that the oysters in the culture cages and the culture cages are constantly rubbing against each other, resulting in the newly grown shells of the oysters. It is knocked off or ground flat, affecting the normal growth of oysters, and the oysters do not grow or grow slowly

If the oysters are cultured in the northern shallow sea, they have to go through the winter, and there will be ice floes in some sea areas in the late winter and early spring. Sink the depth of the breeding cage to avoid the floating ice layer, but because the breeding cage is longer and the floating ice layer is thicker, if you want them not to collide together, and the breeding cage cannot hit the bottom of the sea, you must breed in a deeper sea area Oysters overwinter, which restricts the shallow sea culture of oysters
