Over 1,200 tonnes of fish have so far died in several haors (water bodies) of Netrakona, Sunamganj, Habiganj and Kishoreganj districts, said fisheries and livestock secretary Maksudul Hasan Khan on Sunday, reports UNB news agency.
Of them, Netrakona saw the most deaths of fish, he said while talking to UNB over phone.
The fish might have died for various reasons, including water pollution and falling oxygen level in water due to the formation of ammonia gas after green paddy got rotten following the flashflood, he said.
“We’ll be able to know the details about the reasons of the death of fish after the experts of Bangladesh Fisheries Research Institute submit their report to the ministry as they are now on field visits,” said the secretary.
Talking to reporters at Sunamganj Circuit House on Friday night, Fisheries and Livestock Joint Secretary Syed Mehdi Hasan said the fish died in haors of Sunamganj district as the oxygen level in the water fell due to the formation of ammonia gas.
Huge dead fish were found floating in the haors of the four districts over the last several days after flashfloods hit the areas.
