HDPE Rectangular Cage Aquaculture Trap Crabs and Crayfish Catcher

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Aquaculture Trapping: Designed to efficiently catch crabs, crayfish, and fish in freshwater or saltwater environments using a rectangular HDPE cage with a galvanized steel wire frame.
  • Secure Confinement: The fine mesh HDPE material and sturdy steel frame ensure trapped aquatic species remain secure until retrieval, minimizing escape risks.

Key features

  • 1. Corrosion-Resistant Construction

    • With a galvanized steel frame and high-density polyethylene (HDPE) body, ensure long-lasting durability in aquatic environments. Outperforms traditional plastic traps by resisting UV degradation and saltwater corrosion.

  • 2. Rectangular Shape for Efficient Deployment

    • With a rectangular design, easily stack, position, and retrieve traps in ponds or waterways. Simpler to manage than cylindrical traps in confined spaces.

  • 3. Enhanced Structural Durability

    • With reinforced HDPE walls and steel frame, withstand heavy loads and rough handling. Can handle 20% more pressure than standard plastic traps.

  • 4. Versatile Aquatic Environment Use

    • Designed for freshwater and saltwater environments, effectively trap crabs and crayfish in diverse settings. Ideal for commercial ponds and recreational fishing.

  • 5. Food-Safe Material Compliance

    • Constructed with food-grade HDPE, ensure safe contact with seafood. Meets basic food safety standards for aquaculture equipment.

Product details

HDPE Rectangular Cage Aquaculture Trap Crabs and Crayfish Catcher

The HDPE Rectangular Cage Aquaculture Trap is engineered for efficient crab and crayfish harvesting in diverse aquatic environments. Built with corrosion-resistant galvanized steel frames and UV-stabilized HDPE bodies, it combines durability with lightweight design for easy deployment. Its rectangular shape and customizable mesh configurations optimize species-specific trapping while minimizing bycatch.

Supplier's note

  1. Technical Breakthroughs:

    • HDPE Body: 40% lighter than traditional PVC traps, reducing labor strain.
    • Galvanized Steel Frame: Outperforms industry benchmarks with 25% higher corrosion resistance.
    • Modular Mesh Design: Customizable openings reduce bycatch by up to 30%.

  2. Version Selection Guide:

    • Base Model: Ideal for occasional hobbyists or freshwater use. Its standard HDPE and manual deployment suit small-scale operations.
    • Advanced Model: Perfect for commercial users in saltwater environments. The reinforced HDPE and quick-release hooks cut retrieval time by 20%.
    • Pro Model: Designed for heavy-duty marine use. The Kevlar-reinforced mesh and motorized winch handle extreme abrasion and deep-water deployments.

With the Pro Model’s 15-year corrosion resistance, you can operate in corrosive saltwater without frequent replacements. Pair its reinforced mesh with adjustable openings to target larger crustaceans, ensuring higher yield per deployment.

Note: Comparative values are relative to industry-standard traps using non-reinforced materials.
