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.

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.

The meeting report, covering discussions held 1-2 July 2025 in Shanghai, documents findings from representatives of NACA member governments, FAO and regional organisations.
Participants identified multiple barriers to sustainable intensification: farmer scepticism about unfamiliar technologies, limited access to expertise, and misaligned incentives that prioritise profit over environmental responsibility. Investment remains concentrated at higher levels rather than reaching small-scale producers. The discussions emphasised collaborative approaches, knowledge-based farming systems, and the need to document aquaculture's positive social impacts.
NACA and FAO will continue supporting National Innovation and Investment Plans in India, the Philippines, Thailand and Vietnam. Future work includes establishing an Aquaculture Innovation and Investment Hub and developing monitoring systems to track transformation progress across the region.

This webinar will present the results of an in-depth analysis of Artemia production, conservation and investment opportunities by the World Bank Group, with expert input from members of the International Artemia Aquaculture Consortium.
Artemia (brine shrimp) is a critical live feed in aquaculture, particularly in hatcheries for shrimp, fish, and ornamental species. Its production and sustainable management are increasingly important as aquaculture expands globally. Global Artemia markets face increasing demand, while new innovations in farming, processing, and conservation offer opportunities for inclusive investment, resilience, and biodiversity protection.
This event will bring together global experts, policymakers, private sector representatives, and development partners to discuss the state of Artemia production and conservation, market opportunities, regulatory frameworks, and pathways for sustainable and viable investment.
]]>Bangkok, 21-22 October 2025 - Thailand convened a two-day workshop at the Department of Fisheries to shape a National Innovation and Investment Plan (NIIP) for aquaculture. The meeting formed part of FAO’s Technical Cooperation Programme project TCP/RAS/4004, implemented with NACA, which is supporting India, the Philippines, Thailand and Viet Nam to prepare NIIPs and link them into a shared Aquaculture Transformation Monitoring, Evaluation and Learning System (ATMS) for Asia and the Pacific.

This article reviews evidence that SIS provide bioavailable vitamin A, iron, zinc, calcium and B12, alongside protein and long-chain omega-3s. It examines practical options for including SIS in carp ponds and rice-fish systems, drawing on recent field programmes, and identifies constraints, especially the seasonal, unreliable supply of seed from capture fisheries. The article considers which species are realistic candidates for hatchery production and what husbandry is required. The aim is to give producers, extension staff and policymakers a clear view of when SIS integration adds value, and what investments are needed to pilot and scale it responsibly.

In Meghalaya’s Ri Bhoi district, one farmer shows the way with an integrated fish-duck-poultry system across four linked ponds. Ducks and poultry “pay their rent” by fertilising the water, which powers natural food webs for carp and rohu; simple gravity flow spreads nutrients and improves aeration. Over an eight-month cycle, the farm sells fish, ducks, poultry, eggs and even dyke crops like banana and turmeric - while keeping inputs low and water quality stable. This practical case study explains the layout, stocking plan and daily management behind the results, and why integrated aquaculture is a smart, climate-resilient option for small holders.
]]>Pathum Thani, 5-6 October - NACA participated in the 3rd AQUADAPT Peer-Learning Event at the Asian Institute of Technology Conference Center. Partners reviewed progress on nature-based solutions (NbS) in aquaculture, shared experience and set priorities for the year ahead. The two-day programme combined project presentations, a world-café on climate resilience, and working sessions designed to turn research insights into practice.
The AquaHub project of NACA and FutureFish led a working session on “Knowledge brokering: Private sector engagement and nature-based and inclusive business models,” convening researchers and practitioners to sharpen strategies for scaling NbS through market actors across the value chain, from small-scale farmers and associations to SMEs and larger enterprises. Discussion centred on pragmatic engagement models that can connect research outcomes to investable, inclusive business opportunities.
