Various Types of Copper Alloy Mesh to Improve Fishing Production
CAAM-01: Copper alloy aquaculture mesh is widely used for fish farming.
In the past, people used the polymer fish net as aquaculture mesh because of its cheap price. But there was serious biofouling problem and organic matter blockage impeded the water exchange. All these polluted the water, killed fishes and decreased the fish productivity. Additional, the material was not recycled, which polluted the surrounding environments and wasted of material. Nowadays, there is a type of aquaculture mesh to solve this problem.
Copper alloy mesh is a new type metal mesh used in aquaculture applications. The copper alloy aquaculture mesh, also called copper alloy aquaculture alloy netting, adopts high quality copper alloy wire, which has excellent anti-biofouling performance and anti-corrosion and rust performance. It can increase the water circulation and oxygen content. Moreover, the materials can be fully recycled and it can be used in other applications, so it is environmental protection. The copper alloy mesh can be made into different mesh types according to different fabrication technology.
CAAM-02: Copper alloy welded wire mesh.
CAAM-03: Copper alloy expanded metal mesh.
CAAM-04: Copper alloy crimped wire mesh.
CAAM-05: Copper alloy chain link wire mesh.

Features of copper alloy aquaculture mesh
- Healthy growing environments.
The copper alloy mesh can naturally inhabit biofouling. Besides, it can increase the oxygen content and water circulation to ensure the healthy growing environments and avoid of parasites. It can save at least 15% feeding cost. - Tough structure.
The high strength copper alloy mesh can maintain its cage shapes to withstand the strong ocean weaves and currents. It can also resist the attack from typhoon. The tough structure can also prevent fish crowding and supply enough and free growing space for fishes. - Resist to predators.
Copper alloy mesh has high strength and breaking strength to resist attacks from predators. Additional, it can prevent fishes from escaping from the cages. - Little maintenance.
Different from the traditional aquaculture mesh, which is easy for being blocked by the biofouling, the copper alloy mesh can naturally avoid this problem, so it needs little maintenance effort to clean it. You just need clean one or two once year. - Recycled.
As we all know, the copper alloy mesh has long service life. When it is broken, the materials are fully recycled to be used in initial production of copper alloy mesh or other applications. - Safe.
Copper alloy wire has excellent corrosion and rust resistance performance due to its chemical property, so there is no any anti-corrosive coating, which may pollute the waters. - Durable and long service life.
Copper alloy mesh has tough structure and anti-corrosive performance and other outstanding characters, which ensures the long service life of copper alloy aquaculture mesh. It can last at least 5 years in good condition and property.
CAAM-06: Traditional nylon aquaculture mesh is easy blocking by the biofouling.
CAAM-07: Copper alloy aquaculture mesh can naturally avoid biofouling.
