Shrimp Trade in Trouble, US Tariffs and Disease Outbreaks Threaten India’s Aquaculture Sector

Shrimp Trade in Trouble, US Tariffs and Disease Outbreaks Threaten India’s Aquaculture Sector

Introduction

India’s shrimp aquaculture industry, once hailed as a shining example of rural entrepreneurship and export dynamism, is now facing one of its most difficult phases. From being a driver of foreign exchange earnings and rural livelihoods, the sector today finds itself at a dangerous crossroads. On one side, crippling tariffs and trade restrictions in the United States — India’s largest export market — are eroding margins and making Indian shrimp less competitive. On the other side, recurring outbreaks of diseases like White Spot Disease (WSD), Enterocytozoon hepatopenaei (EHP), and White Feces Disease (WFD) are destabilizing production cycles, leaving farmers uncertain about every stocking decision.

Combined with steadily rising input costs such as feed, seed, fuel, and labour, these twin challenges have created a perfect storm of economic and biological uncertainty. Many shrimp farmers, especially smallholders, now find themselves trapped in a vicious cycle of low farm-gate prices, high risks, and little room for profitability. The result is underutilisation of farm capacity, a sense of hopelessness across the value chain — from hatcheries to processors — and growing fears of a long-term decline in India’s shrimp export dominance.

This article examines the challenges facing India’s shrimp sector, their implications for the economy, and possible ways forward.

India’s Shrimp Export Dependence on the US

India is the world’s second-largest shrimp producer and a global leader in aquaculture-based exports. Yet, despite this strength, the country’s shrimp sector is heavily dependent on a single market: the United States.

In 2024-25, India exported 7.42 lakh tonnes of shrimp globally, of which 3.12 lakh tonnes went to the US. In value terms, exports to the US amounted to around $2.71 billion (₹22,500 crore) — nearly 52% of India’s total shrimp export revenue of $5.17 billion (₹43,000 crore).

This overdependence makes India especially vulnerable to US trade policies. The US primarily imports peeled shrimp products, which means close to half of India’s farmed shrimp output eventually lands in American supermarkets and restaurants. By contrast, India’s shipments to China and Europe often take the form of shell-on or glazed products, which bring lower margins.

Thus, the concentration of high-value peeled shrimp exports to the US has been both a blessing and a curse. While it has provided stable revenues in the past, the recent imposition of steep anti-dumping duties, countervailing duties, and other tariffs — together amounting to nearly 60% — has slashed competitiveness and raised fears of India losing its market share to rivals like Ecuador, Indonesia, and Vietnam, which enjoy more favourable access.

The Disease Challenge

If tariffs were the only issue, India’s shrimp exporters might have found ways to adjust through trade lobbying and diversifying markets. Unfortunately, the biological risks of aquaculture make the crisis far deeper.

Recurring disease outbreaks are undermining farmer confidence and wiping out months of investment in a single stroke. Among the most serious threats are:

1. White Spot Disease (WSD): Highly contagious and capable of decimating entire shrimp populations within days.

2. Enterocytozoon hepatopenaei (EHP): A microsporidian parasite that stunts shrimp growth, leading to lower productivity and smaller harvests.

3. White Feces Disease (WFD): Reduces quality and market acceptability of harvested shrimp.

For smallholders who dominate India’s shrimp aquaculture, a single outbreak can mean financial ruin. Stocking has increasingly become a gamble, with many farmers hesitant to risk resources when the odds of failure are so high.

India’s biosecurity and disease surveillance systems remain weak and fragmented. While some progressive hatcheries and farms are investing in early detection, rapid response, and transparent reporting, the overall systemic capacity is far from robust. Experts point out that unless India strengthens its disease management architecture, no trade concession abroad will secure the industry’s future. A fragile production base simply cannot sustain global competitiveness.

Rising Input Costs

Compounding the twin crises of tariffs and diseases are steadily rising input costs. Feed, seed, fuel, and labour expenses have all increased sharply, even as farm-gate prices for shrimp remain stagnant or volatile.

• Feed costs: Rising global commodity prices have pushed up feed expenses, which account for a large share of shrimp production costs.

• Seed and hatchery inputs: Many hatcheries pass on higher costs to farmers, particularly in disease-prone areas where improved broodstock is in demand.

• Fuel and energy: Shrimp farming is energy-intensive, with pumping, aeration, and processing relying on costly power inputs.

• Labour: Rising rural wages, while positive in a broader socio-economic sense, add to the squeeze on farmer margins.

With costs rising from all directions and revenues either stagnating or shrinking, many farmers feel trapped. The prevailing strategy has been one of “wait and watch,” with stocking decisions delayed until clearer market signals emerge. But this underutilisation of farm capacity reduces overall exports and creates further instability in the value chain.

Domestic Consumption: A Missed Opportunity

Despite being the world’s second-largest shrimp producer, India consumes very little of its own shrimp harvest. Shrimp continues to be treated primarily as an export commodity, with limited demand outside coastal states.

This lack of domestic demand makes the industry excessively vulnerable to global price swings and foreign market access conditions. By contrast, countries like China not only export shrimp but also have strong internal consumption bases, cushioning them from international volatility.

Yet the potential for Indian domestic consumption is enormous. With a growing middle class, rising disposable incomes, and evolving food habits, urban consumers are increasingly open to protein-rich seafood. If even a fraction of India’s domestic consumers embraced shrimp as a regular part of their diets, it could provide much-needed stability. The challenge, however, lies in making shrimp accessible, affordable, and well-marketed across the country.

The Way Forward

India’s shrimp sector stands at a crossroads, but there are several strategies that could help secure its future:

1. Trade Diplomacy: Stronger lobbying in Washington for tariff relief, anti-dumping duty reconsideration, and fairer trade terms is crucial. India must use bilateral and multilateral platforms to push for shrimp’s inclusion in favourable trade frameworks.

2. Strengthening Biosecurity: Disease surveillance must move from fragmented systems to an integrated national program. Investment in laboratories, particularly in Andhra Pradesh and other shrimp hubs, will be key.

3. Market Diversification: Reducing dependence on the US by expanding exports to Europe, East Asia, and the Middle East is vital. Tailored marketing strategies for each region can help reduce risks.

4. Domestic Market Development: Encouraging Indian consumers to embrace shrimp through awareness campaigns, improved distribution, and affordable options like prawn curries in supermarkets could cushion against global volatility.

5. Support for Smallholders: Financial support schemes, crop insurance, and farmer cooperatives could help small-scale farmers absorb risks and remain in the sector.

Conclusion

India’s shrimp aquaculture sector is in a fragile state, caught between external trade barriers and internal biological uncertainties. The country’s heavy dependence on the US, compounded by recurring disease outbreaks and rising input costs, has created a situation where farmers are squeezed from every side.

Yet, the potential for revival is significant. With strategic policy interventions, stronger disease management systems, and efforts to tap into the vast domestic market, India can not only stabilize its shrimp industry but also set the stage for sustainable growth. The choices made today will determine whether shrimp continues to be a symbol of India’s rural enterprise dynamism or becomes a cautionary tale of overdependence and under-preparedness.

Five Questions and Answers

Q1. Why is the US market so important for India’s shrimp exports?
A1. The US is India’s largest shrimp market, accounting for nearly 52% of total export revenues. However, tariffs and anti-dumping duties there have sharply reduced India’s competitiveness, making the sector heavily exposed to US trade policies.

Q2. What are the major diseases affecting India’s shrimp farms?
A2. The key diseases are White Spot Disease (WSD), Enterocytozoon hepatopenaei (EHP), and White Feces Disease (WFD). These biological threats often wipe out entire crops, especially affecting smallholder farmers.

Q3. How do rising input costs affect shrimp farmers?
A3. Costs for feed, seed, fuel, and labour have all increased significantly, while farm-gate prices remain stagnant or volatile. This mismatch squeezes farmer margins and discourages new stocking.

Q4. Why is domestic shrimp consumption in India so low?
A4. Despite being the world’s second-largest producer, shrimp is viewed mainly as an export commodity. Limited awareness, higher prices, and lack of marketing have prevented shrimp from becoming a mainstream protein source in most Indian households.

Q5. What steps can India take to secure the shrimp sector’s future?
A5. Key steps include lobbying for better trade terms, building strong disease surveillance systems, diversifying export markets, encouraging domestic consumption, and providing financial and institutional support to smallholders.
