No reason to think that hilsa will migrate through Farakka barrage
Dr Anisur Rahman speaks to DOT :
Hilsa is a migratory fish. Not all the fish migrate from one place to another. It is not bad for hilsa if they can follow the migratory routes. It is good for us if hilsa can fulfill the life cycle in the maritime boundary of Bangladesh. It will not have any adverse impact on the biodiversity if the fish migrate anywhere after fulfilling the life cycle.
In the event of a flood, it is seen that fish go beyond their boundary, which is not usual. Many of us mistakenly think that all hilsa will migrate to India with the opening of Farakka barrage. However, it requires further research.
Indian authorities have reportedly decided to open the navigation lock at Farakka barrage.
