Sustainable Seafood Revolution: How Naturally-Raised Fish from Dams Are Transforming Local
Livelihoods and Healthy Eating
- By Shailesh Patel, Co. founder, Dam Good Fish
Sustainable seafood, especially fish raised naturally in dams, is attracting increasing
attention. According to the Food and Agriculture Organization (FAO), 34.2% of global fish stocks are
overfished, and an additional 60% are fully exploited. Without sustainable practices, marine biodiversity
and food security are at serious risk. This new form of aquaculture supports the environment, local
economies, and a healthier protein source. The revolution in sustainable seafood is having an effect on
communities and the local seafood market as consumers learn about the benefits of sustainable seafood.
In this context, India has enormous potential: with an existing 3.5 million hectares of reservoirs and
dams—the largest untapped inland fisheries resource in the country—aquaculture based on dams is
becoming a scalable solution.
This new aquaculture project has environmental benefits while providing an economic contribution to local
populations and an alternative source of (hopefully protein-rich) food. India is already the 3rd largest
producer of fish in the world contributing 7.96% of global production, and may be able to capitalise upon
this opportunity in a way that will help advances in ecological and nutritional health while still meeting the
country's economic goals.
The Rise of Sustainable Seafood
For several years, the issues of overfishing and environmental degradation have been
the key issues in the seafood sector. According to the Food and Agriculture
Organization (FAO) of the United Nations, more than one-third of the world’s fish stocks
are overfished. There is a concomitant need for sustainability practices to protect the
aquatic ecosystem and food security.
Scientific stocking of reservoirs in India has been shown to increase fish productivity from just 20–30
kg/ha/year in traditional practices to 150–200 kg/ha/year when managed sustainably (ICAR-CIFRI).
Boosting Local Livelihoods
The economic ramifications of naturally raised fish from dams are significant. The fisheries sector in India
is already generating 1.24% of India's GDP and almost 7% of agricultural GDP supporting the livelihoods
of more than 28 millions.
In rural settings, dam based fish farming provides reliable income. Following sustainable stocking"
practices at Maharashtra’s Jayakwadi Dam, a cooperative of 120 fishermen harvested 40% more fish in
three years.The average household income has risen from ₹7,500 to ₹12,000 empowering families to
spend more on education and healthcare for their children.
Women's engagement has likewise increased. At Ukai Dam in Gujarat, women's self-managed
processing and packaging units produce value added products such as marinated fillets, generating
approximately ₹18–20 lakh per year collectively.. These are a few examples of a wider trend: FAO
estimates suggest that women represent just under 25% of India's fisheries workforce, predominantly in
post-harvest employment, but sustainable dam aquaculture is helping women increase their earnings by
50–70%.
Health Benefits of Naturally-Raised Fish
Consumers are becoming increasingly conscious of the nutritional value of their food.
Naturally-raised fish from dams offer several health benefits compared to fish from
industrial farms.
These fish often eat a natural diet which means they usually have larger amounts of
omega-3 fatty acids, necessary vitamins and minerals. Omega-3 fatty acids contribute
to heart health by burning up inflammation, lowering blood pressure, and improving
heart function. Naturally-raised fish are also less likely to have traces of the dangerous
antibiotics, pesticides and other chemical waste often found in seafood from intensive
farming processes.
Health-conscious consumers who are also considering ecological health are likely to
use sustainably-sourced fish, and as the demand for clean, traceable food sources
grows, so as choice of naturally-raised fish from dams will be a good choice as well.
Naturally-raised fish delivers both nutrition and sustainability.
Omega-3 Fatty Acid Content: Research conducted by the Central Institute of Freshwater Aquaculture
(CIFA) indicates that rohu and catla reared in freshwater dams have 15–20% more omega-3 fatty acids
than fish raised in intensive aquaculture experience.
Less Contaminated: Because fish raised in freshwater dams are less likely to contain antibiotic residues
or pesticides, contaminant risks are minimized compared to fish raised by more chemical-intensive
aquaculture.
Environmental Sustainability and Biodiversity Conservation
Raising fish populations in freshwater dams allows for diminishment of the pressures fisheries apply to
wild fish stocks, as well as benefits marine biodiversity and ecological balance. Sustainable practices,
such as utilizing organic feed, utilizing minimal chemicals, and stocking native species, promotes
preservation of water quality while enhancing the restoration of habitats. Many of the proposed activities
also incorporate elements of reforestation, watershed conservation and enhancement, as well as support
objectives of the National Fisheries Policy 2020 and the livelihoods of residents from surrounding
communities.
Challenges and Future Outlook
Although dam aquaculture provides substantial social, economic, nutritional, and ecological contributions
to the whole of humanity, there remain some barriers to this opportunity which include water quality,
disease management and the regulatory landscape. Several innovations are being piloted to help
address these barriers, including AI-powered feed optimization, IoT-based water quality sensors, and
blockchain traceability schemes.
Food exports for India's average domestic seafood consumption are likely to increase at a CAGR of 7%
until 2030 (OECD-FAO), and with sustainable reservoir fisheries management, India is definitely poised to
sustainably realise this ambition. Further certification type systems, such as the Marine Stewardship
Council, can usefully enhance consumer trust.
If we can continue to invest in, and work together, as community-led reservoir aquaculture will always
have a significant share of India's USD 14 billion fisheries economy, while contributing sustainable
livelihoods, healthier diets, and balancing ecological sustainability.
Infographic Concept: “Naturally-Raised Fish from Dams – A Triple Win”

Conclusion
The sustainable seafood revolution, involving the naturally-raised fish that can be
obtained from dams, provides an important case study in how to create a balance
between economic, environmental and health considerations. This type of sustainable
fish farming delivers new economic opportunities to local communities while advancing
healthy diets and conserving aquatic ecosystems. Staff began working on this at the
same time global awareness and demand for sustainable mechanisms for food
production was increasing. Dam fish farming offers a valuable and replicable and
scalable solution, at exactly the right time. In making this case, I invite consumers,
businesses and policymakers to understand, embrace and support the dam-based fish
farming movement to inspire action in order to collectively advance a more sustainable
and resilient future for seafood production and beyond.
