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.

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.

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%.
