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.

In this issue:

• Ornamental Aquaculture Field School: A new extension approach
• State of the art of carp spawn production and transportation at Ramsagar, Bankura District, West Bengal, India
• Seahorse aquaculture: A new paradigm of commercial activity
• Mixed infections in tropical freshwater fish culture systems: A potential emerging threat for successful aquaculture
• NACA Newsletter

The Farmer Field School approach is promoted by FAO as an alternative technology dissemination mechanism to the top-down extension methods in south-east Asian countries. In order to utilise the potential of the farmer field school approach for aquaculture, ICAR-CIFA has piloted Aquaculture Field Schools (AFS) in several states in India. AFS are schools without walls to improve the decision-making capacity of the farmers and facilitate cross-learning opportunities. It is a participatory extension methodology whereby fish farmers are allowed to choose the methods of aquaculture production through discovery-based approaches.

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.

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.

Exploratory surveys conducted on pristine reef islands has revealed hidden diversity with discovery of two shrimp species new to science, Periclimenella agattii and Urocaridella arabianensis and range extensions for Thor hainanensis and Argeiopsis inhacae. A hands-on training in marine ornamental shrimp rearing was organised at Agatti Island, Lakshadweep during March 2020 to develop a core mass of entrepreneurs to participate in community aquaculture. Another initiative has established a live germplasm resource centre for clownfish, which has ten species conserved in captivity. This facility also serves as a master breeding facility to produce seed for use in a community aquaculture program.

The 11th Symposium on Diseases in Asian Aquaculture (DAA11) marks 30 years since the Fish Health Section - Asean Fisheries Society (FHS-AFS) establishment and it will be celebrated in Malaysia. Local hosts, the Department of Fisheries Malaysia (DOF) under the Ministry of Agriculture and Agro-based Industry together with the Ministry of Modernisation of Agriculture, Native Land and Regional Development Sarawak (MANRED) will be organising the event in cooperation with the FHS-AFS.

The Advisory Group (AG) is a body of technical experts that meets annually to provide advice to NACA member governments on aquatic animal health management. The group is drawn from academia, the private sector and government. The role of the AG is to review disease trends in the region, identify emerging threats and developments in global aquatic disease issues and standards, evaluate the Quarterly Aquatic Animal Disease Reporting Programme operated by NACA/FAO/OIE and regional governments, and to provide guidance on strategies to improve aquatic animal health management. This year’s meeting took place from 18-19 November at the Amari Don Muang Airport Hotel in Bangkok.

This report summarises the proceedings of the 17th meeting of the Advisory Group, held 13-14 November 2018 in Bangkok, Thailand. 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.

In the ornamental fish markets of India, the euryhaline spotted scat Scatophagus argus and pearlspot Etroplus suratensis are popularly sold as ornamental fish. This article describes the nursing of wild-caught spotted scat seed and in-pond breeding of pearlspot to produce marketable sized fish at the Joykrishna hatchery and fish seed farm, located in the Hooghly River estuarine zone in coastal West Bengal, India. The fish are reared in brackishwater ponds for commercial utilisation as ornamental fish, supplying Hyderabad and other cities.

India’s share of the international ornamental fish trade is marginal but has been able to show consistent growth over the years. Of the total ornamental fishes traded by India, approximately 85% are native fishes sourced from the Western Ghats and North East India. The aquaculture of native fishes in seasonal water bodies can play a role in both conservation and generation of livelihoods. Imparting knowledge regarding ornamental fish trade and establishing market linkages is required to further develop the industry.

In this issue:

Rearing of spotted scat and pearlspot in coastal West Bengal, India; harvesting Eurayle ferox (makhana) from wetland fisheries of Assam; prospects of ornamental fish culture in seasonal water bodies in Assam; production of tubifex, a new dimention in aquaculture in feeding juvenile fish; invasive apple snails in Brunei Darussalam; aquaculture trends and opportunities in Sindh, Pakistan; NACA Newsletter.

Apple snails have become a major pest of wetland rice in much of Southeast Asia. Two species are involved, Pomacea canaliculata and P. maculata. One or both of these species have become widely established not only in many parts of Southeast Asia but also in other parts of the world. This book provides an update on research into the biology, management and use of apple snails and highlights the need to prevent further spread of these species.

The objectives of this project were to i) develop a guidebook in English on "Farmer-to-farmer extension approaches for small-scale aquaculture" and ii) to translate the developed guidebook into selected local dialects in Asia-Pacific and other regions (e.g. Africa). The project made use of the significant results from the JICA projects in Cambodia, Benin and other countries on farmer-to-farmer extension approaches on technology extension for small-scale farmers. The book is available in eleven languages (English, Arabic, Bahasa Indonesia, Burmese, French, Khmer, Loatian, Malay, Nepali, Thai and Vietnamese.

Species movement for farming can be one of the many sources of biological threats to the well-being of farmed aquatic animals, humans and ecosystems. Transboundary aquatic animal diseases may occur due to illegal introductions and transfers of live animals. This session will discuss aspects of biosecurity as possible and will identify successes and failures, issues of importance and the role of biosecurity in the sustainable increase in aquaculture production.
