Projects

In June 2024, we installed 14 artificial clay reef tiles on Hundested harbour wall and 10 boulder clay reefs on the seabed at DHI’s testing facility in collaboration with Anemo Robotics and DTU Aqua. Using underwater cameras and AI species recognition, we can see the impact of our artificial reefs on marine biodiversity, which includes a 400% increase in fish abundance and a 200% increase in species.

Duration
June 2024 - June 2025

With Seawilding, 30 temporary artificial oyster reef modules made in proprietary marine-based material, were installed in Loch Craignish. Over the following year, we will assess the survival and growth rates of oysters attached to our reefs compared to oysters on the seabed to assess the suitability of our reefs for oyster restoration.

30 modular reefs in shell-based materials were deployed.

600 Flat European oyster spats glued to reefs, which will be monitored and measured to study the mortality and growth rates.

ReefCircular is currently producing 100 reefs that will be installed in Stubbekøbing Havn, in May 2026.

Underwater monitoring cameras have been installed to establish a baseline of existing marine biodiversity, providing a point of comparison for measuring how ecosystems evolve once the artificial reefs are in place.
