Product Description
HDPE Square Floating Fish Cage
Liftable floating and submersible metal net cage,is composed of submersible deep-sea cage frame, metal fish net and lifting device that can be submerged in water, to form a cylindrical structure. We adopt the combination of lifting suspension cage and platform,to ensure the cage can withstand the impact of a category 12 typhoon.The characteristics of the net cage is that it can be submerged to a certain depth below the surface of the water before the advent of a strong typhoon, so as to avoid the impact of wind and waves.
HDPE, lightweight high-strength alloy materials and other new materials are adopted in the structure. Computer control, various anti-corrosive, anti fouling (attachments) and anti-aging technologies greatly improve the overall structural strength and flexibility of deep-sea aquaculture net cage, double the service life of the cage, highly reduce the daily maintenance and the cost of aquaculture in unit volume, and improve economic benefits.
HDPE Square Floating Fish Cage
For inshore, lakes and reservoirs, good for the square cages which single side length smaller than 15 meters. Include the single cage and combination cages.
1.The cage material is marine special high-density polyethylene material which is environmental and 100% recyclable. It has the advantages of high strength, high toughness, anti-oxidation, acid and alkali resistance, impact resistance.
2. The structure is simple and strong, resistance coefficient is small, strong ability of anti-wind and waves, can withstand the 10 class of typhoon and the 6m waves.
3. Wide range of applications, can be set at -6m to -300m depth of the ocean, river, lake, reservoir etc.
4. The investment cost is relatively low, occupies a large proportion in the domestic dep-water cage culture industry.
5. The bracket(connector) and the column is separated.

FAQ
- Question: What are the characteristics of the material used in HDPE fish cages?
- Answer: HDPE (High - Density Polyethylene) material features high strength, corrosion resistance, aging resistance, and abrasion resistance. It can be used for a long time in complex marine environments like seawater. It is not easily corroded by seawater and can resist the irradiation of ultraviolet rays, thus prolonging the service life of the fish cage.
- Question: How stable is the structure of HDPE fish cages?
- Answer: HDPE fish cages usually adopt a reasonable frame structure design. The HDPE pipes are connected into a stable frame through special connection methods. This structure can withstand the impact of external forces such as wind and waves to a certain extent, ensuring the stability of the fish cage in the marine environment. However, the specific stability is also related to factors such as the size of the fish cage, the installation method, and the environmental conditions of the sea area where it is located.
- Question: How should HDPE fish cages be maintained on a daily basis?
- Answer: Daily maintenance includes regularly checking whether the netting of the fish cage is damaged, and whether there are cracks or damage to the HDPE frame. such as algae and shellfish on the surface of the fish cage should be cleaned in a timely manner to ensure the normal exchange of water. At the same time, check whether the mooring system is firm to ensure the fixed position of the fish cage in the sea. In addition, pay attention to the operating conditions of aquaculture equipment such as aerators and feeders, and carry out maintenance and upkeep regularly.
- Question: What is the approximate service life of HDPE fish cages?
- Answer: Under normal use and reasonable maintenance, the service life of HDPE fish cages is generally 10 - 15 years. However, if the sea area environment is harsh, or if it is severely damaged by external forces during use and not properly maintained, its service life may be shortened.
