Fish die en mass in Thạc Gián Lake

Home Environment

ĐÀ NẴNG — Tens of thousands of fish have died in the Thạc Gián Lake in Thanh Khê District, Đà Nẵng because the amount of oxygen dissolved in water was so low.

Tô Văn Hùng, director of the Đà Nẵng Department of Natural Resources and Environment (DONRE), yesterday explained at the depth of 1.5m, the amount of oxygen was only 0.5mg per litre whereas the regulated level must be 2mg per litre. It was because so much seaweed grew there and took much oxygen.

An early report from DONRE showed revealed thousands of fish were found dead last week.

Mai Mã, director of the Đà Nẵng Drainage and Waste Water Company, said several sewage gates were not working and waste water ran into the lake causing pollution.

The Đà Nẵng DONRE last Thursday sent a letter asking the company to take out the dead fish and treat the affected area to prevent further pollution. — VNS
