A New Initiative to Rescue Oysters

The project aims to restore flat oyster (Ostrea edulis) beds in the central-northern Adriatic Sea. These natural structures, once common and rich in biodiversity, have now almost completely disappeared.

The goal is to recreate a crucial habitat for the balance of the marine ecosystem, as these beds help reduce coastal erosion, promote marine biodiversity, and capture carbon dioxide, all essential services for our marine ecosystems.

Globally, it is estimated that 85% of natural oyster reefs have been lost.

To reverse this trend, PNRR MER (Marine Ecosystem Restoration) ensured OSTREA a project with the task to design interventions to regenerate those marine ecosystems.

At each site, a Resinex elastic beacon has been installed as a fixed monitoring structure.

Resinex’s elastic beacons, thanks to their high adaptability and durability, have proven to be the ideal answer to a demanding project: the stability of observation points, resistance to high wind and current speeds, and waves reaching up to 8.5 meters are some of the challenges we had to face.

Each of the seven elastic beacons installed in the Adriatic Sea reaches different seabed depths, ranging from 12 meters to 29 meters.With a focal point of 7,5 meters, Resinex’s elastic beacons ensure superior visibility compared to traditional floating systems: during the day thanks to the aluminum day shape, and at night through the implementation of  Resinex-CoSeMa self-powered CL301 lantern, visible up to 4 nautical miles.

The walkable platform surface has been expanded to 1800 mm x 1800 mm, in order to accommodate control and data transmission systems, while allowing safe repairs when needed. This space was essential for installing a power pack consisting of four solar panels and four batteries.

The equipment includes a data logger, a 4G router, a surface camera, an underwater camera, and two multiparameter probes.

Each probe is housed in a protective cage and connected to a cable system that allows it to be raised or lowered at different depths.

This initiative confirms our mission: to provide reliable and innovative technologies that meet the most complex challenges of the marine environment. Resinex continues to be the trusted partner for those seeking safety, performance, and tailor-made solutions for every project.
