This report summaries the proceedings of the 21st meeting of the Regional Advisory Group on Aquatic Animal Health, held 17-18 November 2022. The role of the group is to review trends in disease and emerging threats in the region, identify developments in global disease issues and standards, to evaluate the Quarterly Aquatic Animal Disease Reporting Program and to provide guidance on regional strategies to improve aquatic animal health management.

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 2022 and the original and updated reports can be accessed from the QAAD page. 

In June, China will open its doors to the world through the Global Seafood Fair. With over 50,000 visitors and a strong buyer presence, the fair is an excellent opportunity for businesses to showcase their products. The event will feature over 1,000 exhibitors and more than 10,000 products for buyers to choose from. Attendees can also participate in several industry-focused events, including the Global Shrimp Industry Development Summit Forum, the Overseas Seafood Products Digital Trade Forum, the Tilapia Industry Chain Summit, and the China Aquatic Prepared Dishes Development Summit.

Augmenting entrepreneurial attitude among tribal women of Jharkhand through a skill development programme in fish value added products; Culture of hilsa, Tenualosa ilisha in freshwater ponds: Progress and prospects in farming practice; Present status of medium-saline ‘bheri’ fishery and integrated mangrove aquaculture in West Bengal, India: A short study, Part I; Information for farmers on yellow tail catfish, Pangasius pangasius, for easier captive production; Captive breeding and larval rearing of Cirrhinus reba, a small indigenous fish of aquaculture importance; NACA Newsletter.

Cirrhinus reba or ‘reba carp’ is a commercially important indigenous minor carp species distributed over south Asia. It is highly popular among consumers and fetches a better price than the major carps.  An herbivorous species, C. reba can easily digest plant protein sources. It has been identified as a priority species for aquaculture diversification in India and has great scope for incorporation in carp culture and polyculture systems.

The yellow tail catfish Pangasius pangasius is found throughout the rivers of the Indian subcontinent. A large, omnivorous, and highly fecund species, it is suitable for aquaculture. Initial work on captive breeding of yellow tail catfish was carried out by scientists from the ICAR-Central Institute of Freshwater Aquaculture in the early 1990's. This article provides updated information on captive reproduction, larval rearing and nusery techniques for this species, which will be of use for farmers and entrepreneurs interested in producing it.

FAI and NACA will convene a webinar on fish welfare issues on 8 March from 9:30-11:30 am Bangkok time (GMT+7). The webinar will address the relationship between welfare, health, quality and profit in aquaculture production. The programme will feature talks on:

• Animal welfare applied to aquaculture.
• Preliminary tilapia welfare assessment results in Thailand.
• A practical framework for assessments on aquaculture productions.
• Communicating welfare to the aquaculture industry.

Participation is free but registration is required, please download the attached flyer for details.

Since the late 1960s, brackishwater rural aquaculture in West Bengal grew and improved at a fast rate, from an extensive method of farming to a modified-extensive method. The indigenous bheri fishery is a well-known extensive aquaculture system throughout all coastal states of India. Bheri fishery isn’t a capital-intensive practice. This article describes farming practices in bheri systems in West Bengal, India, including their integration with mangrove aquaculture. A second part of this article will be published in the next issue.

Hilsa are a highly favoured food fish on the Indian subcontinent, but wild populations have been declining very fast due to over exploitation and disturbance of their riverine spawning grounds. Hilsa have a complex life cycle, migrating from the sea to riverine environments to spawn and are very sensitive to handling, which has complicated efforts to breed them in captivity. The ICAR-Central Institute of Freshwater Aquaculture has initiated a programme to domesticate hilsa to reduce dependence on wild catch. This article documents the first successful approaches to rear larvae through to table sized fish and to develop mature hilsa broodstock in a farm environment.
