Thousands of fish in Xuan Huong Lake in Da Lat – a major tourist hub in the Central Highlands province of Lam Dong – have been found dead over the past several days.
According to the Da Lat People’s Committee, the cause of the die-off is likely a lack of oxygen in the water accelerated by a combination of a blue-green algae bloom and hot weather.
Prior to the mass fish death, local residents had spotted schools of fish emerging along the lake edge in search of air.

The situation seems to have mostly affected carp, snakeheads, and catfish, with many of the dead fish weighing upwards of two kilograms.
Sanitary workers are still working to remove the dead fish from the lake, but delays caused by the sheer volume of such fish have led to an unpleasant odor to settle over the water surface.
According to a sanitation worker at the lake, on Monday and Tuesday, two trucks carrying a combined 600 kilograms of dead fish took them to a disposal site.

A representative of the Da Lat People’s Committee said household and production waste discharged from upstream agricultural areas and surrounding service-trading areas has affected the lake ecosystem, but the extent of the impact cannot be known until tests are carried out.
