Cage culture is a sustainable aquaculture method that involves rearing fish or other aquatic organisms within a mesh enclosure submerged in a natural body of water. The mesh, a critical component of the system, serves to contain the organisms, allow for water exchange, and protect against predators.   

Types of Cage Culture Mesh

The choice of mesh depends on various factors, including the species being cultured, the water environment, and the desired level of containment. Common types of mesh used in cage culture include:

Nylon: A versatile material known for its strength, durability, and resistance to UV radiation.   

Polyester: Offers similar properties to nylon but may be slightly less expensive.

High-density polyethylene (HDPE): A durable, chemically resistant material often used for larger-scale operations.   

Stainless steel: Provides exceptional strength and longevity, but can be more costly.   

Cage Culture Systems

Cage culture systems can vary widely in size, design, and materials. However, most systems share common components:

Cage frame: The structural support for the mesh, typically made of wood, metal, or a combination of materials.

Mesh panels: The netting that encloses the cage, often secured to the frame with clips or ties.

Mooring system: Anchors or buoys used to keep the cage in place.   

Feeding system: Equipment for delivering feed to the fish within the cage.

Harvesting equipment: Tools or machinery used to remove fish from the cage.
