Method for manufacturing antifouling and antibiosis type yellow croaker net cage

Abstract

The invention discloses a method for manufacturing an antifouling and antibiosis type yellow croaker net cage, which relates to a method for manufacturing a mariculture net cage. According to the invention, the method for manufacturing the antifouling and antibiosis type yellow croaker net cage adopts a buoyancy force system and a netting system, and is characterized in that the buoyancy force system adopts a combination buoyancy force form of 'an anti-aging high-density polyethylene double-floating-pipe cylindrical frame structure + 18 cube cystosepiments with each edge length of 60cm; the netting system adopts a combination structure netting form of 'a first box longitudinal netting + a second box longitudinal netting + a net cage bottom netting; the net cage bottom netting is assembledon a circular high-density polyethylene pipe support which is wrapped with a layer of polyamide multifilament wrap knitting net; and three cross lacing lines are installed at the bottom of the net cage, a polypropylene rope is tied at the cross point of the cross lacing lines, and two foam float bowls which are externally wrapped by double-layer seawater corrosion protection canva and nylon nets are tied at the other end of the polypropylene rope.

Description

Technical field [0001] The invention relates to a manufacturing method of a net cage for cultivating yellow croaker on the sea. Background technique [0002] The existing yellow croaker cages can be divided into square yellow croaker cages and round yellow croaker cages according to their frame shapes. The synthetic fiber netting used in the cages is very fouled and attached during the high-temperature season breeding production, resulting in more frequent changes of nets by farmers. Many. The labor intensity of changing the nets is high and the water exchange between the inside and outside of the cages is not smooth, which affects the normal growth and development of yellow croaker and the efficiency of breeding; in the sea area where the density of cage culture is too high, the water flow is too high and the pollution is serious, resulting in frequent diseases Occurs; synthetic fiber mesh and synthetic fiber rope raw materials are consumed. During the development of yellow cro...

Problems solved by technology

[0002] The existing yellow croaker cages can be divided into square yellow croaker cages and round yellow croaker cages according to their frame shapes. The synthetic fiber netting used in the cages is very serious in high-temperature season breeding production. Too many, the labor intensity of changing the net is relatively high, and the water exchange inside and outside the cage is not smooth, which affects the normal growth and development of yellow croaker and the breeding benefits; in the sea area where the cage culture density is too high, the water flow is not smooth and the pollution is serious, resulting in frequent diseases Occurrence; Synthetic fiber netting and synthetic fiber rope consume a lot of raw materials

During the development of yellow croaker cages, some urgent problems were exposed, such as antifouling of yellow croaker cages, antibacterial problems of yellow croaker cages, energy consumption of yellow croaker cages, bait utilization coefficient of yellow croaker cages, and cage volume The problem of low retention rate etc., these problems are technical problems that have not been solved for a long time in this technical field. The production method is to ensure that the yellow croaker net cage has better antifouling and antibacterial functions, lower energy consumption, higher bait utilization coefficient and box volume retention rate, improves the economic benefits of the yellow croaker net cage, and promotes the sustainable development of the yellow croaker breeding industry. Sustained and healthy development, improving the level of yellow croaker cage facilities and equipment
