Shrimp health: Online Consultation on Strategies for Hepatopancreatic Microsporidiosis caused by Enterocytozoon hepatopenaei (EHP); Webinar: Pathogen Free: Non-infectious Diseases and Disorders of Aquatic Animals; Quarterly Aquatic Animal Disease Report, July-September 2020; Register for the Global Conference on Aquaculture Millennium +20; Scholarship opportunity: Lancang-Mekong Rice-Fish Programme; International Artemia Aquaculture Consortium.

Presenters who identify themselves as youth (< 35 years)  as part of their registration in the Global Conference on Aquaculture Millennium +20 will automatically be entered into a poster competition. Winners have a chance of receiving travel funding (please note the availability of this award will depend on the realities of global travel in September). Winners will also receive an opportunity to present a “lightening presentation” during a plenary session on the last day. This is an opportunity for young researchers to present to a large audience. Winners will also be invited to prepare a brief article for the FAO Aquaculture Newsletter and will have their names included in the Conference Proceedings.

Shanghai Ocean University is offering master and PhD scholarships for aquaculture and hydrobiology-related majors interested in studying rice-fish farming in the Lancang Mekong River area. The scholarship programme is open to nationals of Myanmar, Cambodia, Lao PDR, Thailand and Vietnam who are less than 35 years old and have a bachelor degree with good academic record. The scholarships include full tuition fee waiver, accommodation, living allowance and medical insurance. Applications close 30 May 2021.

This report summarises the proceedings of the 19th meeting of the Advisory Group, held 26-27 November 2020 via video conference. The group's role includes reviewing disease trends and emerging threats in the region, identifying developments in global aquatic disease issues and standards, evaluating the Quarterly Aquatic Animal Disease Reporting Programme and providing guidance on regional strategies to improve aquatic animal health management.

Video recordings of technical presentations from the Online Consultation on Strategies for Hepatopancreatic Microsporidiosis caused by Enterocytozoon hepatopenaei (9-10 February 2021) are now available for viewing via Youtube. Presentations include information on the history of EHP, development of research tools, transmission route and recommendations for its control on farm.

Please visit NACA's Youtube channel to access the videos. Our Youtube channel is brand new, please consider subscribing for more technical aquaculture videos!

The 87th edition of the Quarterly Aquatic Animal Disease Report contains information from fifteen governments. The foreword discusses the 19th Meeting of the Asia Regional Advisory Group on Aquatic Animal Health, held 26-27 November 2020.

NACA is organising an Online Consultation on Strategies for Hepatopancreatic Microsporidiosis caused by Enterocytozoon hepatopenaei (EHP) from 9-10 February 2021 via Zoom. EHP is an important pathogen affecting shrimp health. The online consultation aims to discuss the current status of EHP in the region, and to present recent innovations and currently recommended strategies of control (including information to give confidence that EHP cannot be spread via chilled or frozen export products prepared and packaged for human consumption). Experiences from selected countries which have reported the presence of the disease will be presented and discussed. Participation is free but registration is required.

Exotic trout fisheries resources and potentialities in Uttarakhand; Scenario of captive production of Clarias magur in India; Strategies to reduce feed cost by improving gut health and nutrient utilisation of fish in aquaculture; Fish pituitary gland collection and supply as a vocation in West Bengal, India; Coral trout Plectropomus leopardus aquaculture research and fingerling production in Indonesia; Smartphone app improving smallholder shrimp farming practices in Bangladesh; NACA Newsletter.

Coral trout Plectropomus leopardus is an emerging exported grouper commodity in Indonesia. The demand for coral trout fingerlings has been increasing and the value of this species is the highest among groupers. However, the rearing of coral trout larvae is notoriously more ‘difficult’ than other groupers. This article describes research on coral trout larval rearing protocols conducted by the Institute for Mariculture Research and Fisheries Extension, which has achieved a survival rate of 12%.

In retail fish markets in Kolkata city proper, suburbs and neighbouring districts, pituitary glands are collected as a profession from the heads of mature fish. The preserved glands are used to induce breeding via hypophysation in carp hatcheries throughout West Bengal, playing an important role in the availability of carp seed to support aquaculture operations. This article describes the livelihoods of pituitary gland collectors and traders in West Bengal, India.
