Nine Thematic Reviews have been prepared as an integral part of the GCA +20, under the overall guidance of the International Programme Committee, with the objective to review and update the current understanding on key issues relating to the development of sustainable aquaculture.

A group of experts has prepared advanced working drafts of each Thematic Review and the key findings from each theme will be presented and discussed by expert panels during the GCA +20.

Participants are invited to provide their feedback and perspectives on the reviews and their key messages. The opportunity for providing feedback will be open before, during and immediately after the conference (from 3 September to 15 October 2021). Only comments from registered participants will be considered; please include your registration number in your email. Registration is available here:
