Cage fish farming is a modern aquaculture method used in lakes, reservoirs, and marine waters. It is one of the more cost-efficient production approaches and provides strong operational flexibility.

Producers can culture multiple species in a single water body and relocate cages to optimize farming conditions when needed.

In recent decades, industrial aquaculture methods have increasingly replaced traditional approaches. Cage systems play a key role in maintaining fish stock quality until harvest and market delivery.

Fish cages vary by dimensions, fish species, and deployment location, and are commonly categorized as fixed, floating, submersible, and fully submerged systems. Heavy-duty polyethylene (HDPE) pipe is one of the key products used in modern open-water aquaculture cage systems.

Polidasht polyethylene fish cages provide a secure and stable farming platform engineered for harsh marine weather conditions. These systems are more than simple cages; they are integrated setups with modern equipment designed to maintain safe and efficient conditions for marine aquaculture operations.

  • Lower cost compared with earthen ponds and closed-loop systems.
  • Simpler and more economical operation management.
  • Easier monitoring of fish feeding and health status.
  • More practical treatment against parasites and diseases.
  • Lower capital investment than many alternative systems.
  • Enables multi-purpose pond use by combining cage culture with other aquatic species.
  • Cages can be relocated when suspended solids or environmental pollution create operational risk.

HDPE cages are commonly used for aquaculture in shallow marine areas, with reliable performance in windy and wavy environments. HDPE pipes for these systems include carbon black and UV-protection additives to extend service life under harsh outdoor conditions.

Polyethylene pipes are used in fish-cage systems because of their high resistance to corrosion and tough marine conditions such as saltwater. Relevant tests include:

  • Corrosion resistance tests: evaluate pipe behavior against seawater and chemical exposure.
  • Abrasion resistance tests: verify resistance to wear from water movement and marine contact.
  • UV resistance tests: assess durability against ultraviolet radiation degradation.
