Book excerpt: This report highlights the accomplishments of the Food and Agriculture Organization of the United Nations (FAO) consultations and round-table discussions on the PMP/AB that were held during 2019. These include the following: (i) the Second Multi-Stakeholder Consultation on the Progressive Management Pathway for Improving Aquaculture Biosecurity (PMP/AB2) (29–31 January 2019); (ii) the Progressive Management Pathway for Improving Aquaculture Biosecurity (PMP/AB): First Technical Working Group Meeting (TWG1) (20–22 March 2019); and (iii) the Roundtable Discussions on Aquaculture Biosecurity (22–26 July 2019). It reports on the progress made towards formulating, planning and developing implementation mechanisms for the PMP/AB, based on the comments and recommendations provided by the wide range of stakeholders and experts who participated in these events. In August 2019, the Tenth Session of the Committee on Fisheries (COFI) Sub-Committee on Aquaculture, held in Trondheim, Norway endorsed the PMP/AB and the development of a multidonor-assisted, long-term aquaculture biosecurity component of an aquaculture programme, including its five pillars. Therefore, the FAO, through its Department of Fisheries and Aquaculture, now has a mandate for the further development and implementation of the PMP/AB. Future activities include the establishment of an official Technical Working Group (TWG) that will drive the further development of the technical aspects of the PMP/AB, wider consensus building, initial application (pilot testing) and refinement of the PMP/AB tools, and resource mobilization for the aquaculture biosecurity programme. Guidance documents and resources for advocacy and training on the PMP/AB are currently in development to facilitate adoption at the national level.
