13th Technical Advisory Committee; Presentation of the State of World Aquaculture and Regional Aquaculture Reviews 2020; Online training course on mariculture technologies for the Asia-Pacific region; Quarterly Aquatic Animal Disease Report, January-March 2020; Regional Webinar on Infection with Decapod Iridescent Virus 1 (DIV1) and Preparedness for Emerging Shrimp Diseases; China announces import measures to respond to nucleic acid positives of COVID-19 detected from the outer packaging of frozen white leg shrimp from Ecuador.

In preparation for next years Global Conference on Aquaculture, a series of webinars will be held on topics relevant to the sustainable development of aquaculture. The first of these will be a presentation of advanced (pre-final) versions of The State of World Aquaculture 2020 and six Regional Reviews, which will be held during the week of 26–29 October 2020. These reviews provide up-to-date information on the status and trends of the sector, at regional and global levels, developed from national, regional and global datasets, supplemented with expert opinion and literature review.

The Yellow Sea Fisheries Research Institute, Chinese Academy of Fisheries Sciences and NACA are organising a free online training course on mariculture technologies, to be held from 21-25 September 2020. The programme will cover breeding, disease control and prevention, nutrition and feed research, breeding model construction, farm technology development, engineering, quality, safety and inspection technology for aquatic products. The course is open to government officials, researchers, enterprise managers and technicians from developing countries. The deadline for applications is 19 September 2020.

A Regional Webinar on Infection with Decapod Iridescent Virus 1 and Preparedness for Emerging Shrimp Diseases will be held via Zoom video conference on 10-11 September 2020. This consultation will discuss and plan actions for the prevention and management of this disease. Specific objectives are to:

• Provide updated technological information on DIV1.
• Advocate the strengthening of diagnostic capacities as well as active surveillance of DIV1 (to detect presence or absence of the virus).
• Formulate recommendations on sanitary measures (including biosecurity) for disease prevention.
• Promote emergency preparedness for emerging diseases.

Participation is open to all interested parties but registration is required.
