Cold-Water Fisheries Sector Emerges as Key Driver of Blue Economy and Sustainable Mountain Development

India’s cold-water fisheries sector is rapidly emerging as a vital pillar of the country’s Blue Economy, contributing to livelihood generation, nutritional security, eco-tourism, biodiversity conservation, and sustainable development in mountainous regions. Once confined largely to traditional fishing practices in Himalayan rivers and streams, the sector has now transformed into a modern aquaculture ecosystem supported by scientific farming techniques, advanced hatchery systems, and expanding infrastructure investments.

Cold-water fisheries are primarily practiced in snow-fed rivers, streams, lakes, and reservoirs located in high-altitude regions where water temperatures range between 5°C and 25°C. These ecosystems maintain high dissolved oxygen levels and suitable pH conditions essential for cultivating premium cold-water fish species such as rainbow trout, golden mahseer, and snow trout. Specialized infrastructure including hatcheries, raceways, Recirculatory Aquaculture Systems (RAS), biofloc units, and cold-chain facilities now form the backbone of the sector’s growing aquaculture network.

The sector has gained prominence across Himalayan and northeastern states including Jammu & Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, Arunachal Pradesh, Sikkim, Meghalaya, and Nagaland. Cold-water aquaculture activities are also expanding into hill districts of West Bengal, Kerala, Karnataka, and Tamil Nadu where pilot projects involving advanced aquaculture technologies are being implemented. Together, these regions account for more than 5.33 lakh square kilometres of mountainous terrain rich in freshwater resources and aquatic biodiversity. India has identified over 278 cold-water fish species, making the sector strategically important not only for economic growth but also for ecological conservation.

The growth trajectory of India’s fisheries sector has been particularly significant in recent years. India’s total fish production reached nearly 197.75 lakh tonnes during 2024–25, with cold-water fisheries contributing approximately three percent of inland fish production. National cold-water fish production currently stands at around 7,000 metric tonnes, while trout production alone has increased nearly 1.8 times over the past decade to reach approximately 6,000 metric tonnes in 2024–25.

Jammu & Kashmir has emerged as India’s leading trout-producing region with an estimated production of around 3,010 metric tonnes during 2025–26. The region’s success has been driven by strong government support, modern hatchery infrastructure such as the Kokernag hatchery, and the expansion of more than 2,000 private trout farming units. The fisheries sector has also become an important source of livelihood in the Union Territory, with over 31,000 registered fishers and fish farmers actively engaged in aquaculture activities.

Himachal Pradesh has also established itself as a major cold-water fisheries hub, producing approximately 1,673 metric tonnes of trout in 2025–26 through a network of 909 trout farmers and 1,739 trout farming units. The state has been at the forefront of adopting advanced aquaculture technologies including Recirculatory Aquaculture Systems and has achieved significant success in captive breeding of the golden mahseer, an important indigenous species.

Uttarakhand has recorded substantial progress in cold-water aquaculture with trout production reaching around 710 metric tonnes and total fish production touching 10,486 metric tonnes during 2024–25. The state has expanded nearly 2,500 raceways across districts such as Pithoragarh, Bageshwar, and Chamoli while also promoting fisheries branding initiatives under “UttaraFish.”

Ladakh, despite its harsh climatic conditions and high-altitude desert terrain, has demonstrated the viability of modern aquaculture through the development of 120 raceways and four hatcheries. The Union Territory has crossed 50 metric tonnes of production while achieving local trout seed production targets in areas such as Drass and Chochut.

The northeastern states including Arunachal Pradesh, Sikkim, Meghalaya, and Nagaland are steadily expanding trout farming and hatchery infrastructure, while southern hill regions in Kerala, Karnataka, and Tamil Nadu are increasingly adopting water-efficient technologies such as RAS and biofloc systems to diversify aquaculture practices and improve sustainability.

The rapid growth of cold-water fisheries has also generated large-scale livelihood opportunities. Across cold-water states, over 23.51 lakh families have reportedly received livelihood support linked to fisheries activities, while insurance coverage has been extended to approximately 33.78 lakh fishers under government-supported schemes.

A major driver behind the sector’s expansion has been substantial government investment under flagship schemes and targeted infrastructure programmes. Under the Pradhan Mantri Matsya Sampada Yojana (PMMSY), projects worth ₹21,963.48 crore have been approved nationally during 2020–26, including more than ₹5,638.76 crore specifically sanctioned for cold-water states. These investments have facilitated the establishment of 5,663 raceways, 54 trout hatcheries, multiple Recirculatory Aquaculture System units, nearly 4,600 ponds in Himalayan and northeastern regions, 293 cold storages, and more than 8,300 transport vehicles supporting fisheries logistics.

State-specific investments include ₹317.25 crore for Uttarakhand, ₹155.48 crore for Himachal Pradesh, ₹149.73 crore for Jammu & Kashmir, and ₹33.49 crore for Ladakh. These projects support fish hatcheries, biofloc systems, feed mills, ornamental fisheries, refrigerated transport systems, fish kiosks, and reservoir stocking initiatives aimed at strengthening aquaculture ecosystems and improving market access.

The Fisheries and Aquaculture Infrastructure Development Fund (FIDF) has additionally approved projects worth ₹7,761.78 crore during 2018–26 for the development of hatcheries, training centres, and fisheries infrastructure. Earlier, the Blue Revolution Scheme laid the foundation for scientific trout farming by supporting hatcheries, raceways, and reservoir stocking programmes.

Integrated Aqua Parks established in Anantnag, Udham Singh Nagar, Ziro, and Mokokchung are emerging as modern fisheries hubs equipped with hatcheries, processing facilities, cold-chain systems, marketing support, and value-addition infrastructure. Four Cold Water Fisheries Clusters have also been notified in Anantnag, Pithoragarh, Kullu, and Kargil to strengthen regional fisheries ecosystems and cluster-based development.

Policy support has played a crucial role in the sector’s transformation. The Government has implemented multiple interventions through PMMSY, PM-MKSSY, FIDF, the Blue Revolution Scheme, and extension of Kisan Credit Card benefits to fishers. The recently issued Model Guidelines for Cold Water Fisheries Development, 2026 provide a structured framework covering site selection, hatchery standards, disease management, biosecurity, branding, certification, e-trading, and skill development.

Technology-driven innovation is also reshaping the sector. Startups are introducing smart feeding systems, drone-enabled logistics, digital traceability platforms, and mobile applications that connect fish farmers directly with markets. Cooperatives, Self Help Groups, and NGOs are supporting cluster-based production models, improving women’s participation, and strengthening collective marketing systems.

India is further expanding international collaboration in cold-water fisheries through partnerships with countries such as Norway and Iceland for knowledge exchange in hatchery management, disease control, sustainable aquaculture systems, and export-oriented fisheries development.

Experts believe that cold-water fisheries are no longer a marginal economic activity limited to remote mountainous regions. Instead, they are increasingly becoming a strategic sector that combines scientific innovation, environmental sustainability, rural entrepreneurship, and regional economic development while contributing significantly to India’s broader Blue Economy vision.
