Combined fishnet square net cage used for mariculture

Abstract

The invention discloses a combined fishnet square net cage used for mariculture, relating to a mariculture net cage. In the combined fishnet square net cage, a cupronickel B10 stretching net, a brass HA177-2 stretching net, a high-strenght single-fast-knot polyethylene fibre net, a high-strength nylon warp knitting net, a fishing high-strength polyethylene monofilament rope, a galvanized iron pipe and a cylindrical foam buoy are adopted. The combined fishnet square net cage is characterized in that a frame system used for the net cage is of a square double-row galvanized iron pipe frame structure. In a fishnet system used for the net cage, a double-layer synthetic fibre fishnet serves as a first fishnet, a combined copper alloy stretching net serves as a second fishnet, and the first fishnet and the second fishnet are in longitudinal semi-soft connection; a square synthetic fibre fishnet is in a combined fishnet form of the fishnets used for the net bottom of the net cage; the combined fishnet used for the net bottom of the net cage is hung on the square double-row galvanized iron pipe frame; and the square double-row galvanized iron pipe frame of the net cage is connected with a float line frame of a mooring system by a mooring rope.

Description

technical field [0001] The invention relates to a square net cage for mariculture in the technical field of agricultural science and aquatic products. Background technique [0002] Mariculture cages are an important part of marine fisheries. Mariculture cages can be divided into square cages, cylindrical cages, spherical cages and conical cages according to their frame shapes. The complete set of square net cage equipment and breeding technology has comprehensively applied multi-disciplinary technologies such as new materials, marine engineering, environmental protection, feed nutrition, disease control and breeding management, and has the advantage of simple structure. The nets of the existing square net cages for mariculture use a single form of ordinary synthetic rope net material, and the nets are seriously stained and attached during aquaculture production, resulting in more frequent net changes by farmers, greater consumption of raw materials for rope nets, and box ne...

Problems solved by technology

The nets of the existing square net cages for mariculture use a single form of ordinary synthetic rope net material, and the nets are seriously stained and attached during aquaculture production, resulting in more frequent net changes by farmers, greater consumption of raw materials for rope nets, and box nets. If the clothes are damaged, they will be discarded by farmers. Changing the nets is labor-intensive and the water exchange inside and outside the cages is not smooth, which affects the normal growth and development of fish and the breeding benefits.

Existing mariculture uses a single form of ordinary aluminum alloy mesh, stainless steel mesh or barbed wire material for the metal netting square net cage, and the common aluminum alloy mesh, stainless steel mesh or barbed wire material will be in the cage culture and between the metal frame of the metal net cage. Severe direct wear and tear will lead to serious accidents that the metal mesh net cage will be damaged after several months of use in harsh sea conditions, which restricts the popularization and use of metal mesh mesh cages; ordinary aluminum alloy mesh, stainless steel mesh Or the barbed wire material has corrosion and fouling problems in seawater, and its corrosion and fouling problems also seriously restrict the popularization and use of metal mesh clothing square net cages

During the development of square net cages, some urgent problems have been exposed, such as antifouling of nets, low volume retention of the box, serious drift of net levels, energy consumption of synthetic fiber nets, and metal nets. There are serious direct wear and tear problems between the metal frame and the like. These problems are technical problems that have not been solved for a long time in this field. The combined netting square net cage for mariculture is also a technology that has not been solved for a long time in this technical field. Difficult problem, this technical field urgently needs a kind of combined net clothing square cage for mariculture, to ensure that the combined net clothing square cage for mariculture has better antifouling function, lower energy consumption, smaller net Clothing level drift, higher box volume retention rate, improve the economic benefits of cage culture and the development space of cage culture, and improve the level of cage facilities and equipment
