Nine Thematic Reviews were 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 prepared advanced working drafts of each Thematic Review and the key findings from each theme were presented and discussed by expert panels during the GCA +20. Participants were then invited to provide their feedback and perspectives on the reviews and their key messages. The opportunity for providing feedback was open before, during and immediately after the conference (from 3 September to 15 October 2021). Only comments from registered participants were considered.

Eight of the nine Thematic Reviews have been published in May 2023 as a special issue of the Journal of the World Aquaculture Society (Volume 54, Issue 2) in open access format. The individual articles including an editorial, can be downloaded via the specific links below.
