Workshop on the operational use of Food Web indicators and information (WKFoodWeb; outputs from 2024 meeting)

The Workshop on the operational use of Food Web indicators and information (WKFoodWeb), held in Copenhagen from February 19–21, 2024, focused on the future integration of food web information into ICES advice and progress towards Ecosystem-Based Management and Ecosystem-Based Fisheries Management (EBFM). Key discussions focused on how food web and ecosystem information could compliment the existing ICES advisory framework, including catch advice and Ecosystem Overviews. Invited presentations addressed ecosystem-informed scientific advice, the use of food web indicators, and the development and availability of food web models. Examples from academics, NGOs, and government advisors showcased how ICES might use food web indicators (such as feeding guild indicators and Ecological Network Analysis indicators) to deliver food web information to requesters which is consistent with their objectives under various policy commitments (e.g., Good Environmental Status; GES). Participants emphasised the need for standardised and accessible methods across ecoregions and ICES expert groups with improved data integration, stakeholder engagement, and transparent and robust communication of uncertainties. Breakout groups discussed options for the integration of food web information in advice, where and when needed, by means of pragmatic mechanisms for EBFM and the inclusion of more informative food web products in Ecosystem Overviews. The workshop concluded with actions and priorities focused on 1) synthesizing information and efforts regarding the development food web indicators across ICES expert groups, 2) developing and communicating options for ecosystem-informed fisheries advice, and 3) creating a roadmap for the systematic and transparent use of food web models within ICES.
