Sharks & Rays Found Using Offshore Wind Farms As Habitat - CleanTechnica

A recent study by Wageningen University & Research reveals that offshore wind farms in the Netherlands serve not only as energy producers but also as important habitats for marine life, particularly sharks and rays (elasmobranchs). Using environmental DNA (eDNA) sampling—a non-invasive method detecting species presence through DNA traces in seawater—researchers confirmed the active presence of five elasmobranch species across four wind farms: Borssele, Hollandse Kust Zuid, Luchterduinen, and Gemini. The thornback ray was the most frequently detected, present year-round in several sites, while the detection of migratory basking sharks during winter provided new insights into their seasonal movements. The study highlights that offshore wind farms may act as safe havens for vulnerable species by prohibiting seabed-disturbing activities like trawling, allowing benthic ecosystems to recover and offering more stable habitats. Researchers caution against permitting bottom trawling within these zones to preserve their protective benefits. The findings support
