Experts have attributed the decline to erratic weather conditions, overfishing, navigability issues, and the growing impacts of climate change.

The government has announced the second spawning ground of hilsa and placed a ban on catching the fish during its peak spawning period in an effort to increase production, according to a notification by the fisheries and livestock ministry.

Hilsa experts have said that cyclone Sitrang has created a safe environment for the propagation of the fish even though it has caused heavy destruction in the coastal areas.
