Topic Group "Evaluating the application of artificial light for bycatch mitigation", ICES-FAO Working Group on Fishing Technology and Fish Behaviour (WGFTFB)

Activity: Attending an eventParticipating in or organising workshops, courses, seminars etc.


A WGFTFB Topic Group of experts convened by Noëlle Yochum (USA) and Junita Karlsen (Denmark) was formed at the 2018 meeting in Hirtshals Denmark, to evaluate the application of light as a mechanism for bycatch mitigation. The second meeting of the TG was at the WGFTFB meeting in Shanghai, China in 2019. Due to the Covid-19 pandemic, the 2020 meeting was cancelled and the last TG meeting was held online at the WGFTFB meeting organized by IMR, Bergen, Norway.
Terms of Reference:
1. Describe and summarize completed and ongoing research, successes and ‘failures’, related to the application of light for bycatch mitigation.
2. Identify patterns with respect to species and fishery/ gear types, noting fish behavior in response to light (attraction, repulsion, guidance), and other variables that play a role in the efficacy of using artificial light for bycatch mitigation (e.g. vision, depth, etc.).
3. Describe best sampling techniques for testing the application of artificial light under varying circumstances, including guidance for dealing with common experimental challenges.
4. Highlight areas of needed research in the field of fish behavior with respect to light, and fisheries that might benefit from the application of artificial light.
