After 40 years, Hilsa migrates to Allahabad again

Navigation lock at Farakka Barrage redesigned for Hilsa migration

This monsoon, the Hilsa fish will be able to swim down the Ganga all the way up to Allahabad from the Bay of Bengal. The migration of the fish till Allahabad had been stopped after the Farakka Barrage was built on the Ganga in the 70s. The navigation lock in the barrage that blocked the free movement of Hilsas has now been redesigned to ensure smooth and safe migration of the Hilsa shoal during the three mating seasons. The provision has been made in consultation with ICAR Central Inland Fisheries Research Institute, Central Water Commission and Farakka Barrage Project Authority.
