Developing indicator-based approaches to track and evaluate the ecosystem effects of fishing and the effectiveness of management measures are vital to maintain sustainable resources. This foresight workshop will bring together 30 junior and senior level scientists to evaluate the performance of ecosystem indicators and establish guidelines for future work aiming at determining reference levels at the ecosystem level.

The intention is to provide a better understanding of marine ecosystems and to set up generic guidelines to run simulation experiments across multiple models to build scenarios for marine ecosystems under changing oceans. This is an opportunity to build a network of scientific experts in state-of-the-art regional models of marine ecosystems. Since the network will involve junior and senior scientists from developed and developing countries it will foster the transfer of highly technical skills and knowledge. The scoring of indicator performances may have a major impact on the selection of headline indicators used by international bodies and frameworks. It is intended to publish two to three scientific papers and to present the results at the 2015 ICES annual science meeting as well as other appropriate international fora. 

Three attributes of indicator performance were explored during this foresight workshop: sensitivity, specificity and responsiveness. The participants of the workshop agreed on a final selection of ecosystem indicators to test, running simulations and undertaking statistical analyses to provide R scripts to the group. The result generated standardized and comparable indicators plots for all ecosystems/models addressed, for which figures for the papers were conceived and designed. All results were compiled and recommendations for headline indicators were made.

This collective work has increased understanding of the behaviour of indicators and their utility for Ecosystem Based Fisheries Management (EBFM). This workshop produced a strategic roadmap of research activities related to the use of ecosystem indicators to achieve EBFM, and drafted 5 research papers compiling the results produced by the models. The preparation of precise guidelines on the intercomparability of ecosystem models places the group in a position to address key issues requiring the use of multiple/ensemble modelling approaches over the next decade. Results will be disseminated at different conferences.

The findings of the workshop, including the contents of the papers (which were in preparation at the time), were presented at three conferences in 2016:

  • 7th World Fisheries Congress in Busan, Korea (A. Bundy, Y. Shin co-chair a special session)

  • EcoSummit2016 in Montpellier, France (L. Shannon, Y. Shin co-chair a special session)

  • Benguela Symposium 2016, Cape Town, South Africa
