India has redesigned a navigation lock at Farakka Barrage over the Ganges to ensure smooth and safe migration of the hilsa fish during the three-month spawning season.
It will ensure hilsa's journey up to Uttar Pradesh's Allahabad down the Ganges from this monsoon after a gap of over 40 years, according to a Times of India report run by UNB.
The lock had for long stalled the movement of hilsa from salty waters of downstream Bangladesh to sweeter water in the upstream, particularly during the spawning season.
Bangladesh's national fish Hilsa is holding the recognition of geographical indication (GI) product of the country.
Inland Waterway Authority of India Vice-chairman Pravir Pandey said that the gates of the barrage will remain open for only eight metres and between 1:00am and 5:00am each day, the preferred time when hilsa seeks passage.
This provision has been made in consultation with ICAR Central Inland Fisheries Research Institute, Central Water Commission and Farraka Barrage Project Authority," Pandey said.
