This secondment was used for gathering information and data on the specificities of the North-Eastern Brazilian study case with a focus on the integration of legal information, working in collaboration with P. Fotso (dir M. Bonnin, collaboration with Solange Teles da Silva). This secondment took profit of the Abraços at-sea survey scientific meeting as well as the annual meeting of the International Mixed Laboratory Tapioca (IRD-UFPE-UFRPE). This work allowed the preparation and submission of an abstract for an interdisciplinary oral communication to the Imber FutureOceans2 international conference held in Brest in June 2019 (http://www.imber.info/en/events/osc--imber-open-science-conference/osc-2019/2019-imber-open-science-conference).
