The Future of Ilish Fishing in the Sundarbans: Challenges and Opportunities

 

Introduction: A Cultural and Economic Icon

In the deltaic wetlands of the Sundarbans, where rivers kiss the Bay of Bengal, Ilish (Hilsa) reigns supreme — not just as a fish, but as a cultural and economic lifeline. Revered in Bengali households, featured in festivals, and deeply embedded in traditions, Ilish is more than just a delicacy; it's an identity.

But as we head deeper into the 21st century, the romanticism surrounding Ilish is increasingly clashing with a stark reality — climate change, overfishing, and environmental degradation are posing serious threats to this iconic species. The Sundarbans, one of the most biologically productive and fragile ecosystems in the world, stands at a crossroads.

 

Ilish in the Sundarbans: A Rich Legacy

Hilsa (Tenualosa ilisha), often dubbed the "silver of the sea," is not only the national fish of Bangladesh but also a key species in the Indian Sundarbans, especially in West Bengal's deltaic rivers like the Hooghly, Rupnarayan, and Meghna.

The Sundarbans’ brackish waters, tidal estuaries, and riverine systems create an ideal breeding ground for Ilish, which migrates upstream from the sea to spawn. The fish is deeply linked with the livelihoods of thousands of traditional fisherfolk and contributes significantly to the local economy.

For generations, communities in the Sundarbans have relied on Ilish fishing for income, sustenance, and tradition. Markets from Kolkata to Khulna light up during Ilish season, with prices soaring and consumer demand peaking.

 

 

The Broadening Crisis: Environmental and Economic Pressures

1. Climate Change and Rising Sea Levels

The Sundarbans is one of the most climate-vulnerable regions on the planet. Rising sea levels, salinity intrusion, and increasing cyclonic activity are altering the aquatic ecosystem. These changes affect the migratory patterns and breeding grounds of Ilish.

As water salinity increases and temperature shifts, Ilish populations are migrating further upstream, sometimes beyond traditional fishing zones, making it harder for local fishers to sustain their catch.

2. Overfishing and Juvenile Catch

One of the gravest concerns is the indiscriminate catching of juvenile Hilsa (locally called “jatka”). Fishermen, driven by poverty and lack of regulation enforcement, often resort to catching these young fish, which disrupts the natural breeding cycle and leads to population depletion.

With jatka comprising up to 30% of total Ilish catch during certain seasons, the long-term sustainability of the species is at risk.

3. Pollution and Habitat Degradation

The rise of industrialization along rivers flowing into the Sundarbans has increased water pollution. Dumping of untreated sewage, industrial waste, and plastics has deteriorated the quality of riverine water, affecting fish habitats and spawning zones.

Moreover, rampant mangrove destruction for shrimp farming, settlement expansion, and logging is fragmenting crucial ecosystems that support the Ilish lifecycle.

4. Socio-Economic Insecurity Among Fisherfolk

Many fishers live in extreme poverty with limited access to education, alternative livelihoods, or sustainable fishing tools. Their dependence on daily catches pushes them toward exploitative fishing practices. Moreover, a lack of cooperative organizations, support schemes, and timely policy interventions leaves them vulnerable.

The COVID-19 pandemic, followed by cyclones like Amphan and Yaas, worsened their plight, pushing many to debt traps and forcing some to migrate out of fishing altogether.

 

Narrowing Down: Localized Impacts and Key Stakeholders

Fisher Communities: On the Brink

Traditional knowledge among fishing communities is under threat. As the younger generation sees little economic value in fishing, there's a loss of generational skills. With limited digital literacy and access to information, many are unaware of sustainable fishing practices or government schemes.

Women in the Ecosystem

Women, though not directly involved in fishing, are key players in post-harvest processing, sorting, and marketing. Any disruption in the Ilish economy affects women's employment, food security, and community health.

Local Markets and Export Chains

Ilish contributes significantly to local markets and, to some extent, to cross-border trade between India and Bangladesh. The volatility in catch directly impacts market supply chains, pricing, and trade dynamics.

 

The Way Forward: Opportunities for Sustainable Revival

Despite the grim scenario, hope exists — if timely actions are taken.

1. Strengthening Conservation Policies

India’s National Hilsa Conservation Plan, inspired by Bangladesh’s successful model, can offer a blueprint. Introducing seasonal bans on fishing during spawning times (August–October), incentivizing jatka protection, and deploying monitoring and enforcement patrols can restore fish populations.

2. Community-Based Sustainable Fishing

Empowering local fisher groups with training, gear modernization, and co-management rights can create a sense of ownership. Community-led surveillance and participatory resource management have shown success in similar ecosystems worldwide.

3. Ecotourism and Alternative Livelihoods

Sundarbans’ unique biodiversity can be harnessed for low-impact ecotourism — boat safaris, mangrove interpretation centers, and village homestays — providing alternative incomes to fishing communities, especially during off-seasons or ban periods.

Skill-building in handicrafts, honey harvesting, crab farming, and sustainable aquaculture can also reduce pressure on Ilish stocks.

4. Transboundary Collaboration

As Ilish migrates across borders, India and Bangladesh must enhance cooperation on conservation. Joint research, data sharing, synchronized fishing bans, and knowledge exchange can result in better outcomes for both nations.

5. Use of Technology and Citizen Science

Mobile apps for fisher alerts, AI-powered tools to monitor catch data, and community science programs can involve local youth in tracking biodiversity and ecosystem health.

Blockchain-based traceability of Ilish in the supply chain can also build consumer trust and improve prices for ethical fishing practices.

 

Conclusion: A Delicate Future Worth Fighting For

The future of Ilish fishing in the Sundarbans is at a critical inflection point. Left unchecked, current challenges could spell disaster for both the fish and the people who depend on it. But with integrated efforts — combining science, tradition, policy, and community — the silver shimmer of Ilish need not fade from our waters or our plates.

Protecting Ilish isn’t just about saving a fish. It’s about preserving culture, identity, food security, and a way of life in one of the most vulnerable — yet resilient — regions on Earth.

The Sundarbans has always thrived on balance — between land and sea, human and wild, survival and celebration. It’s time we restore that balance, with the Ilish leading the way.
