This report provides a comprehensive analysis and evaluation of the current state-of-the art in available evidence and science concerning the economic, social, and ecological impacts of offshore wind farms (OWF) and floating offshore wind farms (FLOW) on fisheries in the Baltic Sea, Celtic Seas, and Greater North Sea. It describes the observed and potential economic, social, ecological and cumulative impacts of OWF and FLOW, with a focus on the scope of the existing evidence base, data and methods to assess impacts, and mitigation options to avoid or reduce unwanted impacts. Overall, the workshop to compile evidence on the impacts of offshore renewable energy on fisheries and marine ecosystems (WKCOMPORE) highlights the need for additional high-resolution data, comprehensive assessments, and stakeholder involvement to better understand and mitigate the impacts of OWF and FLOW on fisheries and marine ecosystems. Specific ‘key findings’ arising from WKCOMPORE include: This report was originally published by ICES 2025-04-11 under the CC-BY license.
