In the embodiment, the height of the sinking part is about 3 m, and the specific value is determined according to the local sea bed geological conditions.
[0026] The net 1 is composed of a mesh 101 and a side beam 102, a horizontal beam 103 and a vertical beam 104 bound to the mesh 101. One of the horizontal beams 103 is located at the junction of the mesh 101 and the sea bed mud surface 7. In the embodiment, the side beam 102, the horizontal beam 103 and the vertical beam 104 are made of fiber rope with a diameter of 20 mm, and the side beam 102, the horizontal beam 103 and the vertical beam 104 are connected to the mesh 101 by fiber rope with a diameter of 3 mm. The mesh 101 is made of fiber mesh with a wire diameter of 4 mm and a mesh size of 8 mm, and the mesh size of the mesh 101 is determined according to the size of the cultured objects. The distance between all the binding points is not greater than one mesh size, each binding point is bound by at least two turns, and each binding point has a separate knot. The mesh and the rope share part of the load of the mesh through the side beam, the horizontal beam and the vertical beam. During processing, the mesh and the rope should be spliced / connected as little as possible. If there is a joint, an insertion joint is required.
