The peacock eel Macrognathus aral is a popular ornamental and food fish species found in the Eastern Ghat region of India and Pakistan, Sri Lanka, Bangladesh, Nepal and Myanmar. The species is classed as Low Risk near threatened in the CAMP report. Peacock eel inhabits shallow waters of plains, wetlands, canals, paddy fields, beels and slow-moving rivers with vegetation. Captive breeding is the only way to fulfil demand and protect wild stocks. This article documents the first successful reported captive breeding of M. aral, embryonic development and larval rearing.
Pengba (Osteobrama belangeri) is a near-threatened minor carp endemic to eastern Manipur in India, Yunnan and Myanmar. A migratory species, wild populations of pengba have declined due to the construction of dams and barranges, and possibly also due to the introduction of alien species. Pengba is highly preferred by consumers and attracts a high market price. This article describes the feeding habits and reproductive biology of pengba, and aquaculture techniques for seed production and grow out in monoculture or polyculture.
About 200 families that were displaced by construction of the Jurala reservoir have found new employment in fishing and value-added industry. Local people who up fishing add value to their catch by keeping it for live sale in locally-manufactured cages. Local people also use the live fish to prepare a variety of fresh fish dishes, servicing the tourist trade attracted to the reservoir. Over 400 people are now directly or indirectly self-employed through these practices. This article describes the new practices and the improved income that is being generated by fishers and local entrepreneurs.
Management of waste products produced by fish processing can be an environmental and public health issue. But fish waste can be converted into agricultural fertilisers using simple backyard technology. This article describes techniques for producing fertilisers from fish waste, and a successful demonstration of the technology by the College of Fisheries, Gumla, to tribal communities in the state of Jharkand, India.
This is part 2 of an article describing farming practices in bheri systems in West Bengal, India, including their integration with mangrove aquaculture. 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. Part 2 discusses brackishwater polyculture in South 24 Parganas, including the experiences of farmers implementing an integrated mangrove-aquaculture project, and information on local bheri fisheries derived from published articles.
Arunachal Pradesh is a hill state with a population of 1.38 million in far north-eastern India. With climate ranging from tropical to alpine across a steep altitudinal gradient, the state has a high fish biodiversity and a wide range of aquaculture systems and fishing practices. Both indigenous and exotic species are farmed and fished.
This article describes the species, aquaculture systems and capture fisheries practiced in Arunachal Pradesh as well as their future prospects for further development.
This report summaries the proceedings of the 21st meeting of the Regional Advisory Group on Aquatic Animal Health, held 17-18 November 2022.

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. A 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.
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.
Today, tribal people comprise 8.6 percent of the Indian population and are one of the most disadvantaged sections of society. Many tribal groups in different parts of the country depend on natural resources for their livelihoods, to which their access has been progressively eroded. With financial support from ICAR-CIFT the College of Fisheries, Gumla, undertook seven training programmes for tribal women from economically marginalised tribal communities in the preparation and marketing of value-added fisheries products. The training encouraged women to develop small businesses building on their micro-entrepreneurship.

Hilsa (Tenualosa ilisha) is highly favoured as a food fish by consumers but has a complex life cycle and has proven very difficult to breed. Domestication of hilsa requires extra effort while nurturing the larval stage, which is very sensitive and susceptible to mortality. This article describes standardised protocols developed by the Kalyani Field Station of the ICAR-CIFA Regional Research Centre, Rahara, for artificial fertilisation, incubation and larval rearing of hilsa, as the first steps towards the goal of hilsa domestication and culture.
In West Bengal wild-caught juvenile and sub-adult orange-clawed mud crabs Scylla olivacea are purchased by farms for grow out, fattening, and the production of soft-shell crab for export. This article describes the management practices for producing soft-shell mud crab at National Aqua Farm, using individual box enclosures, and their subsequent processing and packing for export. Details of the crab rearing unit are provided, along with observations of moulting cycles and post-harvest management of soft shell mud crab.
