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. 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.

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.

NACA welcomed five delegates from India on an aquaculture training and exposure visit from 31 October to 4 November. The visit began with a discussion at the NACA Secretariat on Thai mariculture, the recently established International Artemia Aquaculture Consortium, and better management practices concerning hatchery production and use of live feeds. The delegates left Bangkok the next day to visit seabass cage and pond culture and a shrimp nursery in the Chachengsao area and Bangprakong River. The following day they travelled to the Rayong Coastal Aquaculture Center and visited local farm sites before overnighting in Chantaburi. On the final day they visited the Kung Krabae Bay Royal Development Study Center and mangrove walk; and a freshwater fish farm to observe intensive carp and pangasius culture.

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.

Establishing recreational fisheries in Uttarakhand's highland lakes and river systems offers new opportunities to generate livelihoods and income for hill people. The development of catch-and-release sport fisheries can also contribute to conservation of aquatic biodiversity through development of captive breeding technologies, supportive breeding based stock enhancement, and community participation in management of both fishery and habitat. This article describes established and emerging sport fisheries in the highlands of Uttarakhand including for mahseer, goonch and brown trout. It also addresses as yet unrealised opportunities for establishment of recreational fisheries identified through geoinformatic approaches, and partnerships between local communities and government in natural resource management.

Nature-based solutions are interventions that aim to protect, restore and sustainably manage natural and modified ecosystems to benefit human well-being and biodiversity and address societal concerns. Integrated mangrove-shrimp farming or simply aquaculture is the coexistence of mangroves and shrimp aquaculture in a tide-fed environment. In comparison to other shrimp farming systems, integrated mangrove-shrimp farming can additionally produce timber and supports biodiversity. To understand the possible benefits of mangrove integration, our consortium compared three integrated mangrove-aquaculture systems together with three local farmers in North 24 Parganas. This article describes our findings, and important factors to consider before deploying integrated mangrove-aquaculture systems.

Brackish waters offer good prospects for future aquaculture development, as there are fewer competing uses for these resources. Kilarkollai Village (Tamil Nadu, India) has brackish waters on the village periphery, which are under utilised. The majority of the population are landless poor, economically and socially marginalised, and live below the poverty line. A team from the ICAR-Central Institute of Brackishwater Aquaculture demonstrated nursery rearing technologies in partnership with four Scheduled Caste families from the village, with a view to providing supplementary livelihoods and income. The team provided training, initial inputs and technical support.
