Initial attempts to develop freshwater cage aquaculture in India focussed on air breathing catfish and Indian major carps in the Yamuna and Ganga rivers, with later efforts in several large reservoirs. Cage-based aquaculture in inland waters is currently being promoted by some state governments with a view to enhancing fish production. This article examines the history of cage aquaculture in India and some of the factors to be considered in cage design and site selection.

The 78th edition of the Quarterly Aquatic Animal Disease Report contains information from twelve governments in the Asia-Pacific region. The foreword discusses three recent aquatic animal health consultations: The ASEAN Regional Technical Consultation on Aquatic Emergency Preparedness and Response Systems for Effective Management of Transboundary Disease Outbreaks in Southeast Asia; the Regional Consultation and Related Study on Antimicrobial Resistance Risk to Aquaculture in Asia; and the Preliminary Consultation on Monitoring of Antimicrobial Resistance in Bacterial Pathogens in Aquaculture.

The freshwater catfish Heteropneustes fossilis is a high-priced fish, well regarded in India for its nutritional and medicinal properties. The first successful induced breeding of this fish was in 1956 at Bangalore Central College (under the then Mysore University), although seed production was not standardised until 2000, at ICAR-CIFA, Bhubaneswar. This article describes broodstock maintenance, induced breeding techniques and the nursing of H. fossilis larvae in small ponds for sale in fish seed markets.

Annual flooding of the Brahmaputra and Barak rivers provides Assam with some of the finest floodplain wetlands in India. Local people have adapted their livelihoods to the flood cycle and fishing remains a traditional activity of tremendous importance in rural communities, with a diverse range of fishing gear and methods developed. This article documents some of the major fishing gears of Assam, with reference to their efficacy and targeted fish species.

The 77th edition of the Quarterly Aquatic Animal Disease Report contains information from nine governments. The foreword discusses an intensive seven-day training course on tilapia lake virus (TiLV) that was jointly organised by China's National Fisheries Extension Center, Sun Yat-Sen University and the Food and Agriculture Organization of the United Nations.

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.

The 76th edition of the Quarterly Aquatic Animal Disease Report contains information from 14 governments. The foreword discusses the outcomes of a Stakeholder Consultation on Progressive Management Pathway to Improve Aquaculture Biosecurity, organised by the Food and Agriculture Organization of the United Nations, Mississippi State University and the World Bank.

Since 2009, tilapia aquaculture has been threatened by mass die-offs in Israel and Ecuador, caused by a novel Orthomyxo-like (RNA) virus named Tilapia lake virus. An Emergency Regional Consultation for Prevention and Management of Tilapia Lake Virus in the Asia-Pacific was undertaken in September 2017, China, to discuss and plan actions on the overall prevention and management of the disease, and to prevent its further spread. These are the technical proceedings of the workshop.

Mahseer are the most popular game fish amongst anglers in India, with a reputation as one of the toughest fighters amongst freshwater sports fish. In this article, we have made an attempt to compile information on recreational mahseer fisheries in India. The importance of the mighty mahseer as a game fish is told through the perspectives of active anglers and the visions of stakeholders and researchers in conservation and ecotourism are presented.

Jharkhand, India, has a significant population of tribal people, around 28% of the state's 33 million. Agriculture is the main livelihood and subsistence-level farming is predominant, offering limited opportunities for employment to landless people for most of the year. This article documents the experience of the Jharkhand Department of Fisheries in developing cage-based aquaculture as an alternative livelihood for tribal fishers that had been displaced by the construction of reservoirs, working in association with fisher collectives.

Some varieties of freshwater fish have low growth potential but remain economically attractive due to market preferences. The endangered catfish Horabagrus brachysoma is one such fish, which has limited production but high market demand, and a number of favourable biological characteristics. This article provides guidelines for the culture of this catfish in captivity including for the breeding, nursery, stocking and growout, including advice on pre- and post-stocking practices, harvesting and health management.

This report summarises the proceedings of the 16th meeting of the Advisory Group, held 26-27 August 2017 in Bali, Indonesia. 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 meeting included discussion on Tilapia Lake Virus (TiLV) and developments in antimicrobial resistance.
