Hilsa Breeding Grounds Shift From Bengal To Gujarat
Hilsa are fish that live mostly in the sea but swim into rivers to breed.
Traditionally, many hilsa bred around the Ganga-Hooghly system in Bangladesh and West Bengal.
Now, more hilsa are appearing in Gujarat’s Narmada River.
Monsoon water brings nutrients that can make the area better for fish.
Near Bharuch, fresh river water mixes with salty seawater in a way hilsa seem to prefer.
Experts say dams, construction, pollution, changing river depth, and climate change have affected older breeding areas.
Gujarat had a very large hilsa catch in 2025-26.
This has helped fishermen earn more money during the monsoon season.
Some of the fish are sold in Kolkata and Howrah.
Gujarat recorded a four-year-high hilsa production of 14,587.72 metric tonnes in 2025-26.
Inland hilsa production rose sharply from 123.62 to 4,645.99 metric tonnes.
Bharuch produced 7,410.09 metric tonnes, nearly 51% of Gujarat’s total.
Experts link the shift to monsoon nutrients and fresh-saltwater mixing near Bharuch.
The catch supports more than 25,000 fishermen and supplies markets including Kolkata and Howrah.
- Who
- Hilsa, Gujarat fishermen, fisheries officials, and fisheries experts are involved.
- What
- Hilsa production in Gujarat, especially inland production in the Narmada, reached a record four-year high.
- When
- The reported increase occurred during the 2025-26 production year, particularly during the monsoon hilsa season.
- Where
- The shift is centered on the Narmada River and Bharuch district in Gujarat, with fish also sent to Kolkata and Howrah.
- Why
- Monsoon nutrient flows and fresh-saltwater mixing may favor hilsa in Gujarat, while dams, construction, pollution, river-depth changes, and climate change have affected traditional breeding grounds.
