How ICAR's Aqua Village model is raising fish productivity in Meghalaya

ICAR’s Aqua Village Model is a science-led approach to fish farming. It links quality seed, formulated pelleted feed, scientific stocking and pond management with harvesting and value addition. The goal is not only more fish. It also aims to improve nutrition, livelihoods, women’s participation, resource use and rural development.

In Meghalaya’s Ri-Bhoi district, the initiative uses polyculture. Indian major carps are raised alongside Amur common carp, Gonius and silver barb. Farmers receive support across the value chain, from seed production to harvesting. One farmer’s 1,000-square-metre pond is expected to produce 340–400 kilograms after about 11 months.

The model began in November 2025 and helped raise carp production from 1.5 tonnes per hectare in 2025 to 4 tonnes in 2026. It has mainly served local markets so far. ICAR and its partners plan to expand the approach across Meghalaya and other northeastern states.

Government data reviewed by Mint shows a sharp rise in Meghalaya’s carp productivity. It increased from 1.5 tonnes per hectare in 2025 to 4 tonnes per hectare in 2026 under the Aqua Village Model. This is an increase of 2.5 tonnes per hectare, or more than two and a half times the earlier level.

The model farmer, Roiland Mukhim, manages a 1,000-square-metre pond. Its earlier productivity was about 1.4 tonnes per hectare. After stocking 10,000 fish seeds per hectare and raising them for around 11 months, the fish reached an average weight of 450 grams.

Mukhim expects 340–400 kilograms from her pond. Because the pond covers one-tenth of a hectare, that equals roughly 3,400–4,000 kilograms per hectare, or 3.4–4 tonnes. Her result closely matches the district-wide 2026 figure.

The model improves production through several linked practices. Farmers use quality fish seed rather than relying on less controlled stocking. They also use formulated pelleted feeds and follow scientific stocking practices. Together, these measures make pond production more planned and consistent.

In the documented example, the pond was stocked at 10,000 fish seeds per hectare. After around 11 months, the fish reached an average weight of 450 grams. The model also uses polyculture. Indian major carps are raised with Amur common carp, Gonius and silver barb, allowing the pond to support a mix of species.

These methods work as a package rather than as isolated changes. Better seed provides the starting point, planned density organizes the pond, and feed supports growth. Polyculture broadens the production mix. The article links these practices to higher productivity, but it does not provide separate output gains for each practice.

The article presents a clear contrast: Meghalaya has abundant water, but aquaculture productivity has traditionally been limited. It does not name a single cause for this gap. Instead, it focuses on how better scientific practices can make existing ponds more productive.

The Aqua Village intervention in Ri-Bhoi combines quality seed, formulated pelleted feed, planned stocking and integrated resource management. In one example, a 1,000-square-metre pond that previously produced about 1.4 tonnes per hectare is expected to reach 3.4–4 tonnes per hectare. The fish were stocked at 10,000 seeds per hectare and raised for about 11 months.

This result suggests that water availability alone does not determine aquaculture output. Management, technology and farmer participation also matter. The article describes the model as a way to connect research with farmers and build stronger rural economies, but it does not provide a detailed explanation of earlier productivity limits.

When one pond produces more fish, farmers can potentially gain more from the same land and water resource. The Aqua Village Model connects higher production with nutritional security, livelihood diversification and sustainable rural development. These outcomes matter in communities where farming income and food access need strengthening.

The article gives a practical example. Roiland Mukhim’s 1,000-square-metre pond is expected to produce 340–400 kilograms, compared with earlier productivity of about 1.4 tonnes per hectare. The model uses quality seed, feed and scientific stocking to raise output. It also includes harvesting and value addition, which can create activity beyond growing fish.

The initiative has mainly supplied local markets so far. Experts say it can improve farmers’ incomes, create entrepreneurial opportunities for women and youth, and build community resilience. The article does not report a specific income increase, but it presents greater production as the foundation for these broader livelihood benefits.

The model goes beyond raising fish by connecting production with livelihoods and local development. It includes integrated resource management, community participation and the full value chain, from pond management and seed production to harvesting and value addition. This creates roles beyond daily fish care.

Women are central to this approach. Roiland Mukhim is a woman farmer whose pond demonstrates the model’s production potential. Experts also describe Aqua Village as a way to create entrepreneurial opportunities for women and youth. Its focus includes livelihood diversification, rural entrepreneurship and stronger local economies, rather than only higher harvests.

The approach also values local knowledge and aims to build resilience in tribal communities. So far, the model has mainly served local markets. ICAR and its partners plan to replicate it across Meghalaya and northeastern states, linking community participation with goals involving poverty reduction, gender equality, decent work and responsible production.

Aquaculture means raising aquatic organisms under human-managed conditions. In this article, it refers to fish farming in ponds. Farmers control important parts of production, such as the species stocked, the number of fish, feeding, pond management and harvesting.

This differs from catching fish in rivers, lakes or the sea. Capture fishing removes wild fish from natural waters, while aquaculture grows fish in a managed system. The Aqua Village Model uses quality seed, formulated pelleted feed and scientific stocking. It also combines several species through polyculture, including Indian major carps, Amur common carp, Gonius and silver barb.

The article shows aquaculture in practice through a 1,000-square-metre pond in Ri-Bhoi district. The pond is expected to produce 340–400 kilograms after about 11 months. The initiative also covers seed production, harvesting and value addition, making it a wider farming and livelihood system.
