With the implementation of the new aquatic animal disease reporting in the Asia Pacific region from January 2021, and in lieu of the published QAAD Reports (last issue published was 4^th quarter of 2020), NACA is publishing reported aquatic animal diseases submitted by countries in the Asia-Pacific region.  This report covers the fourth quarter of 2021 and the original and updated reports can be accessed from the QAAD page.

• NACA to host the International Artemia Aquaculture Consortium
• Wenzhou virus 8 (WZV8) diagnosis by unique inclusions in shrimp hepatopancreatic E-cells and a molecular detection method
• Report on the Webinar on Management of Artemia Resources of the Great Salt Lake, 5 May 2022
• Twentieth Meeting of the Asia Regional Advisory Group on Aquatic Animal Health

To assist shrimp pathologists worldwide we are providing here photomicrographs of unique basophilic inclusions that are produced by Wenzhou shrimp virus 8 (WZV8),  discovered in 2015 by Li et. al. We designed PCR primers and in situ hybridization probes for detection of WZV8. Subsequent ISH assays with shrimp RT-PCR positive for WZV8 samples indicate unique inclusions described herein as linked to WZV8 in H&E stained tissues. Going back over our previous histological reports and archived slides, we have found the unique WZV8 inclusions in E-cells of normal shrimp samples from several shrimp farming countries in Austral-Asia since at least 2008, and more recently in samples of P. vannamei from the Americas. We urge shrimp pathologists to review their records and specimens for the presence of WZV8 E-cell inclusions described herein to provide data on the global prevalence and impact of WZV8-like infections.

The Fish Health Section of the Asian Fisheries Society is inviting you to a Zoom Webinar on Viral Diseases of Aquatic Animals, 1 June at 13:00 Bangkok time (GMT +7).

Participation is free but advance registration is required.

This report summaries the proceedings of the 20th meeting of the Regional Advisory Group on Aquatic Animal Health, held 4-5 November 2021.

New reviews of aquaculture now available online; Post-doctoral scholarships for women in STEM at the University of Stirling; Research breakthrough seen to curb shortage of "poor man's fish"; Free online aquaculture courses; Fishing for life 2022: South and South-East Asian Conference on Small Scale Fisheries and Aquaculture; Reported Aquatic Animal Diseases in the Asia-Pacific Region during the Third Quarter of 2021; Shrimp 2022: INFOFISH World Shrimp Trade Conference and Exhibition; Tuskfish CMS v2.0.3 available.

We are pleased to announce that the FAO Reviews of Aquaculture have been published online at the FAO website, including the six Regional Reviews and a Global Synthesis, which were developed and published in conjunction with the Global Conference on Aquaculture Millennium +20 (GCA+20). The publications are linked below. Video presentations of the reviews, including expert panel discussions and question and answer sessions, are also available from the GCA+20 website.

With the implementation of the new aquatic animal disease reporting in the Asia Pacific region from January 2021, and in lieu of the published QAAD Reports (last issue published was 4th quarter of 2020), NACA will be reporting aquatic animal diseases that are occurring or present in the countries of the region, on quarterly basis.  This report covers the first and second quarters of 2021 and the original and updated reports are also available.   

Join us on 8 October 2021 for the Professor Sena De Silva Memorial Oration. The topic for the oration is "Aquaculture and marine resources exploitation: reframing the issues", presented by Professor Govanni Turchini of Deakin University and organised by the Sri Lanka Association for Fisheries and Aquatic Resources. The oration will be held at 05:00 GMT (15:00 AEST) via Zoom. To participate, please use the following link: Professor Sena De Silva Memorial Oration 2021.

Join us on 2 September at 12 noon GMT for a free webinar on the Status of the use of Artemia cysts in fish and crustacean hatcheries around the world. The webinar is facilitated by the International Artemia Aquaculture Consortium (under formation). The webinar will document differences in practices used by fish and crustacean hatcheries in the use of Artemia cysts for the preparation of live feeds. Speakers include technical experts using Artemia in the production of shrimp, freshwater prawn, mud and mitten crabs, seabass, sabream and other marine fish from Bangladesh, Brazil, China, Ecuador, Greece, India, Spain, and Thailand. Participation is free but registration is required.

Over the last five decades, over 30 million people along Java’s north coast have experienced subsidence and subsequent soil erosion. In 2015, Building with Nature Indonesia (BwNI-Demak) started a coastal protection project in 10 communities of nine coastal villages of Demak regency. The protection measures introduced included the use of permeable structures (dams) that successfully capture sediment and support natural recovery of mangroves, and aquaculture field schools, to train small-scale farmers on good aquaculture practices such as low external inputs sustainable aquaculture, associated mangrove aquaculture and multi-trophic srhimp aquaculture.

Focussed explorations from the ICAR-National Bureau of Fish Genetic Resources (NBFGR), an organisation mandated for cataloguing of genetic resources of India include surveys of various ecosystems ranging from fauna of deep sea to the high-altitude regions of the Himalaya, falling under diverse biogeographic zones and unexplored regions of the country, including North-eastern India, Western Ghats, Lakshadweep and the Andaman and Nicobar Islands. This article describes the results of these efforts, which include discovery of 14 new fish species and six new distribution records between 2015 to 2020.
