In cage facilities, it is essential to effectively connect two adjacent nets. Improper connection between two nets will lead to the escape of cultured fish in the cage and cause serious economic losses.
At this stage, the netting system adopts the method of direct connection of metal wires to the connection between two adjacent metal trapezoidal nets. The metal trapezoidal nets and the connecting wires are worn out by comprehensive factors such as sea wind, waves, currents and sea water, resulting

Abstract
The invention discloses a connection method for adjacent meshes of a copper alloy trapezius net, relating to a connection method for a mesh of an aquaculture net cage. In the connection method for the adjacent meshes of the copper alloy trapezius net, a cylindrical braid, a rope, a suture line and a tarpaulin ring are adopted. The connection method is characterized in that a soft connecting piece is arranged between two copper alloy trapezius nets, and ring plates manufactured by the tarpaulin ring on the soft connecting piece correspond to screens on the copper alloy trapezius net one by one; one end of a polyethylene rope is fixed on one net knot at one side of the trapezius net, and the other end of the polyethylene rope successively passes through the tarpaulin ring on the soft connecting piece and screens on the copper alloy trapezius net until the other end of the polyethylene rope passes through all the ring plates on the same side of the soft connecting piece and all the screens on the trapezius net; the other end of the polyethylene rope is fixed on one net knot of the copper alloy trapezius net; and the soft connecting piece is connected with the other copper alloy trapezius net with the same method. The connection method is used for connecting the adjacent meshes of the copper alloy trapezius net.
Description
technical field [0001] The invention relates to a method for connecting nets of net cages for aquaculture. Background technique [0002] Cage net clothing is mainly divided into synthetic fiber net and metal net according to its material type. Metal mesh can be divided into trapezoidal mesh, woven mesh and spot welded mesh according to the weaving method; metal mesh can be divided into copper alloy mesh, galvanized wire mesh and steel mesh according to the type of substrate material used for weaving mesh. Compared with ordinary synthetic fiber nets, copper alloy nets have the advantages of antifouling, antibacterial and corrosion resistance. They were first applied in cage pot fisheries, and are currently used in freshwater net cages, offshore seawater net cages and deep water anti-wind and wave net cages. . The connection method between adjacent nets in the cage net system is directly related to the operation safety of the cage facility and its fishery adaptability. In t...
