At least 75 Bangladeshi fishermen were missing and feared drowned because of storms in the Bay of Bengal over the past two days.
Rescuers picked up some 170 fishermen after 15 fishing boats with 245 fishermen aboard capsized during the storms, an official of the Cyclone Preparedness Centre said.
"Only miracles can bring the missing people alive, because survival may not be possible for many due to a very rough sea," said Kabir Ahmed Sawdagar, president of Cox's Bazar Fishing Boats Owners Association.
The storms sweeping the coast line from Cox's Bazar in the southeast to Bagerhat in the southwest also damaged hundreds of houses.
Storms kill hundreds of Bangladeshis every year and the country's worst cyclone left around 143,000 people dead in April 1991.
