Known as ‘glow widow tetra’, ‘glow skirt tetra’, ‘colour widow tetra’ in the ornamental fish industry, a genetically modified variety of the black widow tetra Gymnocorymbus ternetzi is the most favoured by aquarium fish hobbyists in West Bengal. Stunning and sparkling red, blue, yellow, green, pink, orange, and purple bodied colour variations of this tetra have been developed through gene transfer or transgenic technology. The fish glow when kept under blue LED lights, hence the name ‘glowfish’. Maintenance of these brightly coloured and reasonably priced fish in small and medium-sized aquariums at home, the office, hotels, and other settings has become popular in West Bengal, India.

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.

Update: The forum will now be held on 13 December and and updated conference agenda is available below. Please register your attendance using the form linked below. A Zoom link will be sent to all registered participants before the meeting, thank you.

A free online forum will be organised by the Agriculture Trade Promotion Center, Ministry of Agriculture and Rural Affairs of the People’s Republic of China, and Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, and NACA. The forum aims to strengthen international exchange and cooperation in aquatic trade, promote high-quality development of fisheries, disseminate advanced concepts, technologies, and models of aquaculture in the Asia-Pacific region and Silk Road countries, and promote the health and sustainable development of global fisheries. Participation is free but registration is required.

On 28-29 November FAO and NACA collaborated on a virtual workshop to develop a regional strategy for aquatic organism health, using a progressive management pathway for improving aquaculture biosecurity. The workshop was held under the auspices of the project “Responsible use of fisheries and aquaculture resources for sustainable development component 3: Biosecurity and health management”. The workshop involved 31 experts from 16 countries, including national focal points, FAO and NACA. The objectives of the workshop were to: Present and analyse country responses to a self-assessment survey on biosecurity and health management capacity and performance; to provide guuidance to country participants on conducting a SWOT analysis; and to prepare a detailed plan for Phase II of the initiative.

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.

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.

Ocean University of China and partners will convene the forum from 20 to 22 November 2022. The forum will cover the following: Topic 1: International talent cultivation and training;Topic 2: Science and technology innovation; Topic 3: Industrial synergy. The forum will host discussions about the implementation of the “Blue Transformation” strategy, further expansion of the space for fisheries and aquaculture, and ways of improving the production capacity of aquatic products, with the purpose of facilitating the achievement of the UN Sustainable Development Goals. Participation is free but registration is required. Registration closes on 22 October.

Hatchery production of stinging catfish (Heteropneustes fossilis) seed is increasing as it is a good fish species favoured by consumers due to its high protein and lower fat content. Stinging catfish naturally breeds in the monsoon season, and is found gravid in the wild during July-September. In captivity it can be successfully produced using either induced or natural breeding techniques. This article summarises what is known about stinging catfish biology, and methods for its captive breeding, rearing of larvae and fry, feeding strategies and health concerns, to aid production of seed of this valuable catfish.
