Artificial intelligence for sustainable fishing

The Game of Trawls project, led by Ifremer in partnership with the Obelix team (IRISA/UBS), Marport, Comité départemantal des pêches et des élevages marins du Morbihan, is a project that aims to develop new technologies that can actively improve the selectivity of fishing gear.

Based on a pun with a well-known TV series, Game of Trawls is the acronym for Giving Artificial, Monitoring intElligence tO Fishing Trawls, this scientific project aims to make the selectivity of trawl blows dynamic.

Given that the selectivity of trawls is currently mainly passive, i.e. that the escape of unwanted species depends on the fish themselves and their willingness to escape the trawl, the objective of the project is to move to active selectivity.

The Game of Trawls project therefore proposes a new approach to selectivity that gives the initiative to the fisherman, i.e. the fisherman will make the decision to keep or not keep the caught fish in his trawl by operating an exhaust system. To do so, it will rely on a series of sensors that will inform in real time of the species caught, the abundance and size of these catches and the impact of the fishing gear on the marine environment. Its long-term ambition is to significantly reduce accidental and unwanted catches, and thus better protect marine ecosystems. It will also enable professional fishermen to take an even more active role in promoting sustainable and responsible fishing.

Mobilizing approximately 1.5 million euros financed by the European Union, the French government and France Filière Pêche, Game of trawls will be run until December 2021. As an academic partner, the Obelix team of IRISA through UBS is involved in this project in the areas of IT, artificial intelligence, mathematics and materials design. As an industrial partner, Marport France will work on the research and development of instrumentation for environmental measurements, geometry and acoustic imaging. Finally, CDPMEM 56, a professional partner, will provide its expertise on the transferability of sensors designed for real trawls in fishing action.
