Fishing bans, about 1 to 22 Oct 2027
Mother hilsa fishing ban, Bangladesh
For 22 days around the full moon of Ashwin, Bangladesh bans catching, selling and moving hilsa so the spawners can breed.
Hilsa spawn most heavily around the full moon of the Bengali month of Ashwin, in October. To let the egg-carrying mother hilsa breed, Bangladesh bans catching, transporting, storing and selling hilsa across the country for 22 days around that moon. In 2026 the ban ran from 8 to 29 October. Fishers registered with the government receive rice during the closure. The government links the ban, with protection for young hilsa, to the large rise in the hilsa catch since the 2000s, though enforcement on remote rivers is uneven. The 2027 dates here are an estimate.
