EWG 24-16 was tasked with the development of a bio-economic modelling framework to assess the impact of the implementation of technical measures. The EWG focused on tool preparation (data and code); framework application (two case studies); and framework development to identify additional aspects required to fully operationalise the bioeconomic and social assessment of the impact of technical measures within Western Waters and Mediterranean. This work builds on the body of research conducted in four previous working groups that focused on the review of the technical measure's regulation (EWG 20-02, EWG 21-07, EWG 22- 19, EWG 23-15). The previous EWG’s (20-02, 21-07, 22-19) developed several tools to translate and apply the finding of gear selectivity studies to the single species stock data to produce selectivity indications which could estimate the likely impact of selectivity measures on stocks. EWG 23-15 focused on the implemen-tation of the technical measures regulation by identifying the tools, steps and routes required to operationalise a bioeconomic (ecological, economic and social) impact assessment of the technical measures. To assess the impact of the technical measures requires multidisciplinary expertise. This expertise was well represented at EWG 24-16 which was attended by 18 experts (biologist, economist, gear technologist, mathematicians and social scientists), including 1 JRC staff; 1 representative from the Commission; and 10 observers from diverse backgrounds including Advisory Councils. The Terms of Reference to the EWG were all addressed and an overview of the findings in the report can be summarised as follows: • EWG 24-16 progressed the development of a decision support tool to assess and visualise the short-term bioeconomic impact assessment of technical measures. It will take another year to fully operationalise the process of providing robust and transparent advice using this tool for short term projections. • ToR 1 reviewed the outputs of an ad hoc contract to determine suitability of data and code provided for implementation during the EWG 24-16. The material and report provided by the ad hoc were successfully implemented during EWG 24-16 • ToR 2 documented the application of two bioeconomic case studies on hake mixed fisheries using the data and code presented in ToR1. One case study on the Bay of Biscay using the model developed by ICES WGMIXFISH advice. The second case study on EMU2 (GSAs 8, 9, 10, 11) using the model developed by the STECF West MED MAP EWG. • ToR 3 utilised the experience of experts and observers to determine what scenarios could be tested in these specific studies, and what scenarios would be of relevance to the specific fishery and management challenges in these regions. Once operational, these decision support 3 3 tools will provide a platform by which to easily explore trade-offs to a spectrum of different scenarios. • ToR 4 summarised the remaining steps required to fully operationalise a short-term forecast application over the next year for the two identified case studies; and what is required to operationalise a long-term forecast over the next 2 years.
