Colour widow tetra: A new and highly preferred aquarium fish in West Bengal

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.

First report on successful captive breeding of peacock eel, Macrognathus aral

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.

Present status of medium saline ‘bheri’ fishery and integrated mangrove-aquaculture in West Bengal, India, Part 2

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.

Shrimp Summit, 24-26 July, Ho Chi Minh City, Vietnam

The 2023 Shrimp Summit will convene the global seafood value chain to address the critical challlenges of Asia’s shrimp-farming sector, from stagnant production to growers’ livelihoods, with a cross-topic focus on sustainability and climate change. The Summit is presented by The Center for Responsible Seafood (TCRS) and co-hosted by the Global Seafood Alliance. The format of the 2023 Shrimp Summit will allow the industry to develop a common understanding of issues, address key challenges through discussion and work toward consensus and actionable solutions. This in-person and virtual event will feature discussions, relevant content and informative webinars before, during and after the event in the TCRS Online Community. Access to the online community is included with event registration.

13th Asia-Pacific Marine Biotechnology Conference, 2-6 October 2023, Australia

The 13th APMBC and 5th ANZMBS conference are combining to engage marine biotechnologists, industry, investors, and policy makers in current marine biotechnology research, and industry development in the Asia-Pacific region. The conference will be held from 2-6 October 2023 in Adelaide, Australia. This provides a great opportunity to participate in the growth and future development of the marine biotechnology industry in the region and globally. A key objective of the joint Conference is to encourage academic-industry partnerships across the region. Abstract submissions and early bird registrations are now open!

Captive breeding and larval rearing of Cirrhinus reba, a small indigenous fish of aquaculture importance

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.  An 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.

Information for farmers on yellow tail catfish, Pangasius pangasius, for easier captive production

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.
