In Assam and across north-eastern India, the NGO Kalong-Kapili is helping rural families turn unused ponds, wetlands and beels into a source of food and income. Working with ICAR-CIFA, the organisation began in 2007 at Bagibari village and now runs a Field Laboratory and an Aquaculture Field School that train farmers in scientific fish farming, disease management, climate-resilient practices and integrated farming. This article describes how the model has spread to tribal clusters in Borbeel, Lohit and Lower Siang, benefiting hundreds of families through fish farming combined with horticulture, piggery and kitchen gardens.
It also covers Kalong-Kapili's work to empower women through self-help groups, its production of fish seed, and CIFA's outreach scheme reaching forest-dependent communities in West Karbi Anglong. Together these efforts show how aquaculture extension can reduce poverty and malnutrition while building lasting skills in remote regions.

For decades, catfish farming in India stayed marginal for one reason: seed. Consumers preferred catfish and paid more for it, yet most indigenous species depended on wild fry collected from rivers and floodplains. Supply was seasonal and unpredictable, so farmers kept returning to reliable carp.
This article traces how ICAR-Central Institute of Freshwater Aquaculture worked over nearly five decades to remove that constraint. Rather than treating breeding as a single step, scientists tackled the whole production system: broodstock nutrition, induced spawning, hatchery design, larval feeding and nursery management. Progress came across species from small bagrid Mystus spp., Rita chrysea, the pabda group Ompok species, the yellow catfish Horabagrus brachysoma, magur Clarias batrachus, singhi Heteropneustes fossilis, Clarias dussumieri, Pangasius pangasius and the predatory, cannibalistic Wallago attu.
The result includes low-cost FRP hatchery units, stage-specific formulated feeds and dependable seed for farmers across many states. It also describes how captive breeding eases pressure on threatened wild stocks and supports conservation alongside aquaculture.
The melon barb (Haludaria fasciata) is a lemon-striped freshwater fish found only in the hill streams of the Western Ghats in Kerala and Tamil Nadu. Prized by the global ornamental fish trade, its wild populations are falling as deforestation, sand mining, and pollution degrade its habitat. This article sets out a science-based method for breeding the species in captivity, from conditioning broodstock on protein-rich diets to managing spawning tanks, larval feeding, and water quality. It also covers the economics: a small hatchery can be set up for a modest sum and produce thousands of juveniles per cycle, giving rural households a supplementary income. By supplying farmed fish to domestic and export markets, hatcheries ease pressure on wild stocks and support brood banks for conservation. The melon barb shows how ornamental aquaculture can link rural livelihoods with the protection of freshwater biodiversity in the Western Ghats.

The Western Ghats are home to a distinctive group of small, bottom-dwelling fish: the loaches. Adapted to fast-flowing hill streams, they have elongated bodies, sensitive barbels around the mouth, and cryptic patterns that blend into rock and gravel. The region holds at least 43 loach species across 12 genera, 39 of them endemic, the result of long evolutionary isolation in mountain streams. This article describes their body forms, habitats, feeding habits, and behaviour, and profiles well-known species such as the Zebra loach (Botia striata) and the Zodiac loach (Mesonoemacheilus triangularis), both popular in the global ornamental fish trade. It also outlines the pressures these fish face, including habitat degradation, dam construction, pollution, and unregulated collection. Most Western Ghats loaches still lack legal protection, and the article reviews their conservation status and the measures needed to safeguard them.

Seaweed farming in India has long been confined to open coastal waters. But researchers are now proving that commercially valuable species can thrive in brackishwater ponds, lagoons, and tanks, especially when grown alongside shrimp, mud crab, and finfish. This article from ICAR-Central Institute of Brackishwater Aquaculture explains how integrating fast-growing Gracilaria and Ulva species into existing farms turns waste nutrients into a second cash crop, improves water quality, and raises the survival and quality of the animals farmed with them. It covers the most promising species, practical cultivation methods, and real field results: more than a three-fold increase in seaweed biomass, shrimp survival above 95%, and reduced feed conversion ratios. It also looks honestly at the hurdles - seed supply, salinity swings, disease, and pricing - that must be solved to scale up.
Along the coast of Purba Medinipur in West Bengal, sun-dried marine fish - known locally as 'Shutki machh' - has grown from a traditional way of saving surplus catch into a thriving regional business. At the Matsya Khoti of Junput-Biramput village, where commercial drying began some 70-75 years ago, around 550-600 producers now sort, salt, and dry fish on raised bamboo platforms before sending it to markets across north-east India, Nepal, Bhutan, and Bangladesh.
This article takes a close look at how the dried fish trade works: the species and methods, the road transport network, the food culture and recipes carried into West Bengal by refugees, the women whose labour underpins much of the work, and asks what is needed to keep this tradition healthy and sustainable.
On 28 April 2026, the NACA Secretariat was privileged to welcome Dr. Abhilaksh Likhi, Secretary of the Department of Fisheries, Ministry of Fisheries, Animal Husbandry and Dairying (MOFAHD), Government of India. Dr. Likhi, who led a high-level delegation from the Indian Embassy, visited NACA’s Bangkok headquarters to engage in discussions aimed at deepening the collaborative bonds between India and the regional aquaculture community.
The visit underscored India’s pivotal role as a founding member of NACA. For decades, India has remained a cornerstone of the organisation, contributing significantly through the Indian Council of Agricultural Research (ICAR). During the meeting with NACA Director General Dr. Eduardo Leano, the delegation discussed advancing regional aquaculture development with a specific focus on aquatic disease surveillance and transboundary knowledge exchange, sharing insights on how innovation can further modernise the sector.
AquaInnovate 2 brought together 12 startups, scientists, and industry leaders in Bangkok from 23-27 March 2026, continuing the momentum to accelerate nature-based solutions and climate innovation across the Asia-Pacific, with financial from Canada's International Development Research Centre.
The week blended intensive learning with practical experience. Entrepreneurs pitched breakthrough ideas in biotechnology, community enterprise, and regional scaling, then refined their business models through expert coaching circles. Field visits to innovative Thai aquaculture sites connected theory with real-world practice, while a high-stakes "Shark Tank" session challenged innovators to defend their ideas before experienced investors and business leaders. A culinary showcase highlighted the importance of engaging buyers and chefs as essential partners in market success - not just scientists and farmers.
The week concluded with the unveiling of the AquaHub Vision, a roadmap for a permanent digital platform to sustain and grow the pan-regional network of aquaculture innovators into 2026 and beyond.
Videos of workshop presentations will be available on this page and NACA's YouTube channel shortly.

Small-scale farmers in the Indian Sundarbans are transforming their livelihoods through brackishwater ornamental fish farming. The region's estuaries and mangrove forests provide natural habitat for commercially valuable species like spotted scat, green puffer, pearlspot, and orange chromide. With training from ICAR-Central Institute of Brackishwater Aquaculture's Kakdwip Research Centre, local entrepreneurs have developed successful hatchery and grow-out operations.
Three farmers from Kakdwip Block demonstrate the sector's potential. Mr Tapan Maity produces 1,000-3,000 fingerlings monthly from his integrated facility. Mr Mahendra Dului operates a 32-tank hatchery using cost-effective farm-made feeds. Mr Aurobindo Haldar cleared his debts within three years of starting pearlspot production. These farmers combine scientific broodstock management with local knowledge to rear juveniles for urban pet markets in Kolkata and Howrah. The expanding domestic and export demand for brackishwater ornamental species offers sustainable income opportunities for coastal communities facing challenges from climate vulnerability and limited livelihood options.
India's inland waters produce 70% of the nation's fish, yet up to 20% spoils before reaching consumers due to poor post-harvest handling. In Tripura, where people consume fish at four times the national average, a surprising entrepreneurial story is emerging from this challenge.
At Agartala's Durga Chowmuhani market, 22 young people have turned fish dressing into profitable businesses. Working four-hour morning shifts, these mostly unemployed youth earn Rs. 530-680 daily, incomes exceeding the state average, by cleaning small indigenous fish that retailers refuse to process. Their startup cost was just Rs. 500 for a specialised knife and Rs. 50 daily for market space.
This informal sector reveals strong market demand and employment potential. However, challenges remain: inadequate hygiene facilities, limited cold storage, and variable food safety standards. The path forward involves supporting what works - strengthening informal businesses with training, better tools, and gradual infrastructure improvements rather than waiting for large-scale formal facilities.

Access to quality seed has long constrained aquaculture of magur, a high-value indigenous catfish prized across north-eastern India. Wild stocks have declined, yet demand continues to rise. In Nalbari district of Assam, scientists and farmers have created a solution. ICAR-Central Institute of Freshwater Aquaculture worked with local farmers to establish more than 25 magur hatcheries using innovative fibreglass-reinforced plastic designs suited to flood-prone conditions. Farmers received training in captive breeding, hormone-induced spawning, and larval rearing using specialised feeds. Individual farmers now produce 300,000-500,000 fry per season, earning substantial income while supplying seed across multiple districts. The model shows how targeted capacity building, appropriate technology, and farmer-centred interventions can transform indigenous fish seed production from a critical bottleneck into a thriving regional enterprise. Approximately 70 farmers now actively supply magur seed where scarcity once limited aquaculture expansion.

Rearing stinging catfish larvae has long challenged Asian fish farmers, as young catfish naturally prefer live prey over manufactured feeds. A West Bengal farmer has developed a method that produces one million catfish fry monthly using Moina zooplankton, as the sole food source. After training at ICAR-CIFA research station, Mr Imran Molla established 25 large tanks to mass-produce Moina using simple ingredients like waste bread and mustard oil cake. He segregates catfish larvae by age into separate compartments and feeds each group appropriately sized Moina. The larvae thrive on this natural diet, reaching sale size in 30 days with high survival rates. This method requires less water management than manufactured feeds, reduces disease risk, and generates substantial income. The farmer's success demonstrates how combining scientific training with local innovation can solve critical bottlenecks in small-scale aquaculture.

Asian seabass has emerged as a promising alternative to shrimp farming in coastal Andhra Pradesh. This article documents the complete production cycle practiced by farmers in Krishna, Eluru and West Godavari districts, from wild egg collection to market-ready fish.
The production process spans 14-16 months across multiple phases: two nursery stages transform eggs into fingerlings, a pre-grow-out phase develops juveniles to 100-200 g, and a final grow-out period produces fish weighing 3-4 kg. Farmers rely heavily on live feed, primarily small shrimp and tilapia, with feed conversion ratios around 6:1.
While the species offers advantages such as fast growth and salinity tolerance, farmers face challenges including fluctuating export prices, rising feed costs and disease outbreaks. The lack of species-specific therapeutics further complicates disease management. Most harvested seabass currently reaches export markets through Kolkata and Chennai, though opportunities exist for domestic value-added products.
The giant featherback (Notopterus chitala) - valued as food, sport fish, and natural pest controller in carp ponds - remains under-utilised in Asian aquaculture despite strong market demand. Limited knowledge of seed production has constrained commercial development, whilst wild populations face pressures from overfishing and habitat loss.
Researchers at ICAR-Central Institute of Freshwater Aquaculture have compiled practical knowledge on captive breeding and larval rearing of this air-breathing species. Their findings address key challenges: establishing brood stock, triggering natural spawning using hard substrata, managing sensitive larvae through the critical first weeks, and preventing disease transmission from live feeds.
The techniques described offer farmers a pathway to reliable seed production, potentially easing supply constraints whilst reducing pressure on wild stocks. The work demonstrates how systematic documentation of breeding protocols can unlock aquaculture potential for neglected native species with conservation value.
In Purba Medinipur, India's leading fisheries district, two farmers are exploring new directions in aquaculture. Sri Buddhadeb Maity has established commercial farming of the prized murrel (Channa striatus), achieving growth rates of 250-300g within two months. His neighbour, Sri Uttam Manna, has taken an unconventional approach: cultivating freshwater aquarium fish in brackishwater ponds near the Bay of Bengal.
Manna's method challenges established practice. He has observed fewer disease problems than those typically encountered in freshwater aquarium fish operations, potentially due to the salt content in his ponds helping to control pathogens. Both farmers have developed profitable enterprises whilst sharing their methods with neighbouring producers, encouraging diversification across the region.
