Transform your coral cultivation with our V-shaped raceway, designed for efficiency, scalability, and optimal growth.

  • Modular and Expandable Design: Tailored to meet the specific needs of your restoration project, allowing for easy expansion based on space availability and coral output requirements.

  • Innovative V-Shaped Structure: Reduces sedimentation stress and mortality rates for juvenile corals, ensuring healthier growth. Facilitates optimal water flow, enhancing the overall health of corals.

  • Energy Efficiency: Inspired by natural winding rivers, our design promotes efficient water movement, reducing energy consumption compared to traditional land-based systems.

  • High Capacity: Each 2-metre section of the raceway accommodates 10 frag trays, holding a total of 216 coral settlement plugs per tray. This means each section can house up to 2,160 coral settlement plugs, maximising your grow-out capacity.

  • Expanded Capability: Modular design allows for additional sections to be added, up-to 24 V lengths, providing a maximum capacity of over 50,000 coral plugs.

  • Seamless Integration: Complements our broodstock and embryo rearing systems, creating a comprehensive solution for coral spawning, settlement, and growth.

The Maternity Tray is meticulously engineered to efficiently manage large quantities of frags. Its integrated soft silicon layer ensures a secure grip on the plugs, allowing for safe transportation without the risk of dislodgement.

​

Key features include:​

  • Integrated Handles: These facilitate secure handling, even in sea-based nursery environments.

  • Compatibility: Designed to seamlessly integrate with V-Shaped Raceways.

  • Capacity: Each tray can accommodate up to 216 of the 20x20mm settlement plugs, 54 of the 40x40mm plugs, or 60x60mm plugs, or a combination of all three sizes (plugs sold separately).

Optimised for Settlement and Early Post-Settlement Survival

  • Textured Surface: Enhances larval settlement and promotes early post-settlement survival.

  • Square Design: Maximises space efficiency, increases surface area for settlement, promotes even distribution, and prevents overcrowding in settlement hotspots.

  • Available in 3 sizes: 20x20 mm, 40x40mm and 60x60mm (coming soon)
