Anchoring and positioning

  • Anchored to the bottom (ropes, chains, poles, or concrete blocks) to prevent drifting.

  • Modular cages can be connected in batteries or groups.

  • Adjustable height depending on water level and hydrodynamic conditions.

Use in aquaculture

  • Suitable species: trout, carp, tilapia, sea bass, sea bream, etc.

  • Environment: pond, reservoir, lake, or calm coastal area.

  • Management:

    • Manual or automatic feeding.

    • Monitoring of stocking density, water quality, and net condition.

    • Regular cleaning to avoid clogging.

Advantages and limitations

Advantages:

  • Simple, modular installation.

  • Good oxygenation due to water exchange.

  • Moderate cost compared with stainless-steel cages.

Limitations:

  • Biofouling risk, requiring frequent cleaning.

  • Shorter lifespan than rigid HDPE or steel structures.

  • Prone to tearing if not well maintained.
