In the fiscal year 2022-2023 alone, the government allocated INR 1,800 crore to support infrastructure, technology adoption, and farmer welfare in the sector.
The Growth of Aquaculture in India
Aquaculture in India has become a vital driver of socio-economic growth, significantly strengthening the country’s economy and rural livelihoods. Between FY 2014-15 and FY 2021-22, the sector recorded an impressive annual growth rate of 8.61%, with the Gross Value Added (GVA) rising from ₹76,487 crore to ₹1,47,518.87 crore (constant prices). Its contribution to the National GVA increased from 0.844% in FY 2013-14 to 1.069% in FY 2021-22. Similarly, its share in agricultural GVA climbed from 4.75% to 6.86%, underscoring its growing role in enhancing rural incomes and addressing nutritional security.
India’s aquaculture boom has driven a significant increase in fish availability and consumption. Per capita fish consumption has grown from less than 5 kg in 2013-14 to 13.1 kg today, with a goal to reach the global average of over 20 kg. Supporting this growth, the government has issued 4.32 lakh Kisan Credit Cards (KCCs) to fishers and farmers, enabling credit access worth ₹2,687.20 crore. Infrastructure investments totaling ₹9,532.30 crore have modernized fishing harbors and fish landing centers, ensuring safer, more efficient operations and enhancing the post-harvest value chain.

Technological advancements have been a game-changer for India’s aquaculture sector. Through initiatives like the Pradhan Mantri Matsya Sampada Yojana (PMMSY), cutting-edge systems such as biofloc and Recirculatory Aquaculture Systems (RAS) have reduced production costs while boosting yields. Over 52,000 reservoir cages and thousands of RAS and biofloc units have been deployed. Inland aquaculture has also expanded, with over 23,000 hectares of ponds converted into productive resources, increasing average productivity to 5 tons per hectare and targeting 6.5 tons per hectare by 2029.
Diversification and sustainability remain central to India’s fisheries strategy. Genetic improvement programs for indigenous species like tiger shrimp and scampi, along with the domestication of non-native species, are fostering ecological resilience and export potential. Investments in cold-water fisheries, ornamental fish units, and seaweed cultivation are diversifying livelihoods while promoting environmental harmony. A dedicated seaweed park in Tamil Nadu exemplifies efforts to empower coastal communities, particularly fisherwomen.
Policy reforms and digital initiatives have streamlined aquaculture operations and accessibility. Amendments to the Coastal Aquaculture Authority’s regulations now encourage eco-friendly practices and ease of doing business. Platforms like the National Fisheries Digital Platform (NFDP) facilitate credit access, insurance, and traceability, while ISRO-developed communication devices for fishing vessels enhance safety at sea, reflecting the government’s commitment to inclusive growth.
Looking ahead, India’s vision under the Viksit Bharat@2047 plan includes ambitious targets of producing 400 lakh tons of fish annually and increasing global export share to over 8% by 2047. Key initiatives, such as artificial reef installations, integrated aqua parks, and hatchery expansions, are building a sustainable and prosperous aquaculture sector. By leveraging innovation and scaling up efforts, India’s fisheries industry is set to become a global leader, creating opportunities for millions and propelling the nation towards a thriving blue economy.
How Technology is Transforming Aquaculture
The adoption of technology has been a game-changer for aquaculture farmers in India. Modern farm management systems are replacing traditional practices, enabling better productivity, sustainability, and profitability. Technological advancements such as biofloc systems, recirculatory aquaculture systems (RAS), and cage culture have revolutionized fish farming. In the past four years alone, 52,058 reservoir cages, 12,081 RAS units, and 4,205 biofloc units have been sanctioned, driving efficiency and production.
Over 60% of aquaculture farmers now employ technology-driven methods, leading to an average yield increase of 25-30% and a reduction in feed conversion ratios by 10-15%, according to the Confederation of Indian Industry (CII).
