Neolissochilus hexagonolepis (chocolate mahseer): A flagship species for diversification of hill aquaculture in Northeast India https://enaca.org/?id=1322&title=neolissochilus-hexagonolepis-chocolate-mahseer-a-flagship-species-for-diversification-of-hill-aquaculture-in-northeast-india

This article investigates the ecological, economic, and cultural importance of Neolissochilus hexagonolepis, commonly known as chocolate mahseer and its potential for hill aquaculture in Northeast India. The taxonomy, distribution, and distinct features are described. Chocolate mahseer populations are in decline due to habitat degradation, overfishing and environmental changes, and it is designated as "near threatened" by the IUCN. Breeding patterns, growth parameters, and culture techniques are explored in depth as a candidate species for aquaculture development. Conservation initiatives and the need to balance economic utilisation with species conservation in chocolate mahseer farming are discussed.

Aquarium fish culture in open village ponds in South 24 Parganas, West Bengal https://enaca.org/?id=1323&title=aquarium-fish-culture-in-open-village-ponds-in-south-24-parganas-west-bengal

The article highlights the successful commercial-scale breeding, propagation, rearing, and sale of aquarium fish species in the Howrah and South 24 Parganas districts of West Bengal, India. It focuses on the innovative practices of two experienced aquarium fish farmers, Sri Bikash Sau and Sri Swapan Parua, who have introduced a novel approach to aquarium fish culture in open earthen and common village ponds. The success stories of Sri Bikash Sau and Sri Swapan Parua serve as inspirations for small and medium-scale farmers and aqua-entrepreneurs. Their innovative approach to open pond production for aquarium fishes demonstrates the increasing potential and expansion of the aquarium fish business in the region.

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.

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.

Pengba, Osteobrama belangeri – a candidate species for diversification in aquaculture https://enaca.org/?id=1277&title=pengba%2C-osteobrama-belangeri-a-candidate-species-for-diversification-in-aquaculture

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.

Innovative fish sale improved livelihoods at Jurala dam in Telangana, India https://enaca.org/?id=1276&title=innovative-fish-sale-improved-livelihoods-at-jurala-dam-in-telangana%2C-india

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.

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.
