The Thai Fish Project began in 2019, and involves around 200 research members and multiple institutions in Thailand and Japan. The project aims to promote domestication and wise use of two Thai native aquatic species, namely the Asian sea bass Lates calcarifer and banana shrimp Penaeus merguiensis through increasing productivity, reducing the impact of infectious diseases, and preserving genetic resources. The project also encompasses several specific research topics to ensure that it comprehensively addresses the concerns on safeguarding the food security and enhancing the environmental sustainability as much as possible. This article describes the main research activities, outputs and future expectations of the Thai Fish Project.

Naihati fish seed market as state-of-the-art for sustainable support services to fish growers, buyers and traders https://enaca.org/?id=1305&title=naihati-fish-seed-market-as-state-of-the-art-for-sustainable-support-services-to-fish-growers%2C-buyers-and-traders

Naihati fish seed market of West Bengal was established in 1976 and is the largest seed market in India. With the advent of induced breeding technology and hatcheries, fish seed is now available almost year-round, catering to the need of Indian farmers. Situated in North 24 Parganas, Naihati wholesale fish seed market is a well-known establishment that provides multifaceted services to stakeholders including fish seed growers, retailers, sellers, and mediators. This article describes the state of the market as aspects of its evolution over time.

Genetic management of Indian major carps https://enaca.org/?id=1296&title=genetic-management-of-indian-major-carps%3A-a-case-study

Collectively carps represent the largest global aquaculture sector, contributing over 20 percent of global aquaculture production. The Indian major carps including catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirhinnus mrigala) are cultured widely across the Indian sub-continent with the main culture system being a multi-species polyculture in ponds, often including other carp species. This production sector is supported by major seed supply systems producing over 50 billion seed per annum. This case study analyses genetic management of Indian major carps since they were first domesticated with the development of hypophysation techniques in the 1950s. A review of literature and a survey of common hatchery practices identifies significant problems prevalent in the sector brought about by a lack of application of best practices in genetic management resulting in loss of genetic diversity, inbreeding and uncontrolled hybrid introgression.

Colour widow tetra: A new and highly preferred aquarium fish in West Bengal https://enaca.org/?id=1284&title=colour-widow-tetra%3A-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 https://enaca.org/?id=1278&title=first-report-on-successful-captive-breeding-of-peacock-eel%2C-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 https://enaca.org/?id=1273&title=present-status-of-medium-saline-%E2%80%98bheri%E2%80%99-fishery-and-integrated-mangrove-aquaculture-in-west-bengal%2C-india%2C-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.
