The fisheries minister’s statement to parliament has not received the scrutiny it deserves. Hilsa output fell from 566,593 tons in the 2021/22 fiscal year to an estimated 419,500 tons in 2025/26, a decline of nearly 26 percent. The path of that decline is instructive. A slight rise to 571,342 tons in 2022/23 was followed by successive falls to 529,487 tons, then 502,444 tons, and finally the present estimate.
The final drop, about 16.5 percent in a single year, is the steepest of the period, which suggests not slow erosion but a deterioration that is gathering pace. Hilsa accounts for roughly 10 percent of national fish production and is the largest contributor of any single species, so the consequences reach far beyond one fishery. They touch nutrition, rural livelihoods and the country’s cultural identity.
Root Causes
The ministry’s reply catalogues interventions without diagnosing the problem, and that omission is itself revealing, since a response that does not name its causes cannot be judged against them. The drivers most likely operate at several levels at once, and they reinforce one another.
Fishing pressure is the most visible driver. Hilsa fetches a premium price, which creates a standing incentive to harvest juveniles and spawning fish and to use prohibited nets, an incentive that enforcement across vast river systems and a dispersed, poor fishing population has never matched. Habitat degradation is the deeper and slower problem. Hilsa moves between sea and river to feed and spawn, and it needs continuous deep channels, sufficient dry season flows and tolerable water quality. Siltation, shifting riverbeds, sand extraction, effluent and reduced upstream flows erode these conditions and can fragment the migratory corridor. Climate change magnifies each stress, as rising salinity, warmer waters and erratic monsoons shift the timing and location of migration and spawning, so that protective bans may no longer coincide with breeding.
These are inferences from the species’ known ecological dependencies, not findings from the ministry, and the lack of a published causal assessment is itself a governance weakness. Fuel shortages this year may also have reduced fishing effort, so part of the latest fall could reflect fewer boats rather than fewer fish. Only an independent stock assessment can tell the two apart.
The Weakness of the Official Response
What the minister describes are activities completed, not results achieved. Six sanctuaries have been established, livestock has reached 26,176 fishing households, and 17,500 fishers have been trained. Yet none of these numbers show that the hilsa stock is rebuilding, and each looks modest beside a fishing population that is generally believed to be considerably larger.
The livestock scheme also assumes that riverine households have the skills, fodder and market access to turn animals into reliable income, which many do not, and it does nothing to replace earnings during the ban period itself. Sanctuaries, for their part, safeguard fish only where breeding habitat remains intact and the rules are genuinely enforced. Food aid that covers less than the income fishers give up during bans risks provoking the very violations it is intended to deter.
The minister’s observation that retail prices are set in wholesale auctions, beyond the department’s authority, is factually sound but telling. It shows that scarcity is being transferred to consumers, and that a fish once at the center of everyday diets is gradually becoming a luxury.
Agricultural Sustainability
The sustainability implications are broader than the fishery alone. Hilsa is a sensitive indicator of river health, and its decline signals pressures shared with floodplain agriculture, including salinity intrusion, sedimentation and contamination from agrochemicals and industrial waste. It also exposes a statistical illusion.
Growth in pond aquaculture can mask the contraction of capture fisheries in aggregate figures, giving a false impression of food security while the wild resource and the livelihoods tied to it deteriorate. Many fishers are bound to advance lenders and boat owners, so falling catches deepen debt and push households toward the very practices that deplete the stock. The result is a self-reinforcing cycle of poverty and overexploitation that sanctuaries and one off assistance cannot break.
For the Government
Reversing this requires a shift from counting activities to measuring results. The government should begin by commissioning and publishing independent stock assessments that track catch per unit of effort, juvenile ratios and spawning success, so that policy responds to evidence rather than to the volume of programmes. Habitat restoration needs equal weight: maintaining river channels, regulating sand extraction, enforcing effluent controls, and pursuing dry season flow commitments through water diplomacy with upstream neighbors.
Compensation during bans should be indexed to realistic forgone income and delivered promptly, so that compliance becomes economically rational. Enforcement should move up the supply chain to the manufacture and sale of illegal nets rather than punishing only the poorest fishers, and communities should be given genuine authority in managing sanctuaries, with a stake in their success. Credit reform to loosen the grip of advanced lenders, together with climate research on shifting migration routes, would complete the response.
Conclusion
A 26 percent decline in five years is not a statistical blip. It is the river’s verdict on a management approach that rewards activity over evidence. If the government keeps announcing programmes without confronting habitat, incentives and data, the next parliamentary answer will simply report a larger number.
