The fish deaths have caused the severe pollution in Danang.
On Wednesday, it was easy to see the dead fish in a canal running along Chon Thanh Tam 6 in Lien Chieu District. Most of the fish were tilapias.
The fish was collected and sent to Khanh Son Dumping Site to be treated.
People living around the canal have suffered from serious pollution due to the dead fish.
Nguyen Thi Viet Nga from Hoa Khanh Nam Ward said during the summer, the water in the canal often becomes very foul and is covered with scum.
Some days ago, around 500 kilos of dead fish were found in the Phu Loc River, while the figure was 1,500 kilos at Trung Nghia 1 Lake.
The Danang Drainage and Wastewater Treatment Company claimed the fish had died because the Phu Loc River saw a sharp decline in oxygen content in the water amid the hot weather.
Over the past three days, torrential rains caused a sudden change in the water environment in Trung Nghia 1 Lake, resulting in mass fish deaths on July 17.
Fish have been gathered for testing.
