Fish from a lake in the 29/3 Park in the central hub were discovered having died en masse on Monday, releasing a foul smell upsetting many local visitors.
Most of the dead fish were adult tilapias, some of which weighed up to two kilograms each. A smaller number of common carp and shrimp also suffered the same fate.
The incident was noticed by hikers along the lake during the morning and quickly reported to managers of the venue.
In an interview with Tuoi Tre (Youth) newspaper, Dang Duc Thu, director of the Da Nang Green Tree Park Company which manages the lake, confirmed that fish started dying early in the morning, adding that the phenomenon had worsened by the end of the day.
The situation was later reported to the Da Nang Drainage and Wastewater Company, the firm in charge of supervising the quality of the pond, according to Thu.

Mai Ma, director of the company, said that his employees had salvaged the bodies of the dead fish with their weight expected to total over two metric tons.
The cause of the mass deaths has yet to be determined, Mai said, adding that the phenomenon was not unprecedented.
A water sample of the lake has been taken for examination while the lake will be sterilized with lime in the meantime, the director continued.
He added that the water in the pond could not be replaced entirely due to a lack of resources.
