Advantages of aquaculture cage system

Cage culture is the main way of mariculture and has broad prospects for development. Since the 1990 s, the rapid development of marine cage culture in China has produced significant social and economic benefits. The traditional net cage structure is simple, mainly made of wood, steel pipe or other materials, they have poor resistance to wind and waves, small scale, short service life and other shortcomings. The traditional cage setting sea area is limited and can only be concentrated in the inner bay and near shore, resulting in over-dense aquaculture in some sea areas, pollution, diseases and other problems becoming more and more serious, seriously affecting the development of marine aquaculture. The pipes and fittings for marine aquaculture HDPE net cage system produced by our company use high density polyethylene as raw material and are molded by extrusion injection molding. In addition to the characteristics of good corrosion resistance, environmental protection and durability, smooth surface and low flow resistance of common plastic pipes and fittings, they also have the advantages of good toughness, high strength and high safety factor due to the use of imported PE special materials as raw materials and innovative warehouse structure technology. As a new product, Yatong's marine aquaculture HDPE cages have greatly improved their comprehensive performance in wind resistance, wave resistance, ocean current resistance and other aspects than traditional cages. They are more convenient, safe and efficient in use and are well received by the industry.

1. High economic benefit

Cages large volume, high output, suitable for large-scale production, enterprise operation. Away from the bay, land, good water quality, excellent environment, high recovery efficiency of survival rate. The growth rate is fast and the quality of the cultured seafood is high.

2. Strong wind and wave resistance, high cold resistance and long service life

The marine aquaculture net cage is made of pure imported HDPE material with high density and high toughness, which can resist 12 typhoons and can withstand water temperature of minus 50°C. The service life can reach more than 15 years. It is suitable for deep sea and lake recreational aquaculture.
3. Environmental protection, no pollution, recyclable
Marine aquaculture cages are made of HDP material, which does not produce pollutants and has strong corrosion resistance and good flexibility. The breeding cage is protected by a safety fence and can adjust the sagging depth of the fishing net.
4. Expanding ocean space
Because the marine aquaculture cages made of HDPE material have the characteristics of strong wind and wave resistance and long service life, it is suitable for deep-sea aquaculture far away from land-based pollution, which can greatly transfer the pressure of offshore aquaculture and expand the aquaculture area,
5, strong defensive
Marine aquaculture cages are protected by safety guardrails and can adjust the sagging depth of fishing nets.

The main performance of marine aquaculture cage system:

Wind resistance: Level 12
Anti-wave ability: 5M
Flow resistance:<1 M/S

Comparison of system performance and structure

Product standard and application field

Product Standards

1. The products are produced according to the enterprise standard Q/LS-58-2015;
2. The company mainly produces cage pipe products with standard size ratio of SDR11SDR17;

3, the product color is generally black and yellow, can also be agreed by the supply and demand sides;

4. The length of net cage pipe is generally 9m or 12m, which can also be agreed by both parties.

Application areas

1, in the fish industry, used to build a variety of aquaculture cages;

2. Various water environments such as large fish ponds, reservoirs, hydropower stations, docks, and seaports are used to build floating frame sightseeing, operating platforms and pontoons.

Deep sea round cage display

Deep-sea round net cage is also called offshore platform net cage, which is surrounded by HDPE buoyancy pipe and is fixed upright by anchor and net. In a bad climate the whole ocean platform is soaked in waves to maintain good resistance to wind and waves.

Tension buffer anchoring system: the use of anti-wind and wave tension buffer device, with multi-point anchoring system, the impact of wind and waves will be dispersed, so that the cage has the ability to resist wind within 12 levels and waves within 5 meters.

Advantages: high strength, good flexibility, corrosion resistance, anti-aging, strong ability to resist wind and waves, long years of use, large effective aquaculture water body. The efficiency comprehensive cost is low, the pollution is small, the water quality is worried, the fish mortality rate is low, the fish product quality is excellent, the benefit is good, the return is high-shelf system.

Deep sea round cage display

The frame system is made of HDPE pipe for high strength seawater cages, made of special polyethylene raw materials. This pipe has good strength and toughness.

Through the design of our frame connection, the frame has the ability to resist 12 typhoons. At the same time, the frame material is subjected to high-tech treatment technology of anti-ultraviolet aging and anti-seawater corrosion, and the service life is more than 15 years.

Deep sea square cage display

Features: high economic efficiency, strong resistance to wind and waves, high cold resistance, long service life. Using high density and high toughness HDPE material special design anti-slip pattern, pedal design structure is stable.

Features: The use of pure imported high-density high-toughness HDPE material, one-time high-pressure injection molding, with a compartment system to improve safety. The three-way sleeve butt connection mode realizes the overall performance of the inner and outer buoyancy pipes, reduces the force of the bracket, prolongs the service life, and improves the wind and wave resistance.
