Authorities in Thanh Hoa Province, located in north-central Vietnam, on Saturday reported over 30 metric tons of dead fish in aquaculture cages, in the natural environs of the Ngoc Pond area in Nghi Son Town, and several other locales along the province’s coastline.
The mass fish die-off has killed 25 metric tons of farmed fish on the Ngoc Pond, as well as four metric tons of fish in the natural habitat along the seaside area, according to leader of Nghi Son Town.
A total of 32 out of 55 fishery households in Nghi Son reported severe losses from the incident, local authorities added.
After being notified of the mass fish deaths, the aquaculture and environmental officials of Thanh Hoa Province have arrived at the scene to collect samples of the dead fish and water for further inspection.
Relevant agencies of Nghi Son Town have instructed fish cage farmers to collect death fish and dispose of them properly, harvest the remainder to salvage the financial damage, and distance the fish cages to make space for the living ones.
By Saturday afternoon, residents of Nghi Son Town had reported the cessation of the mass fish deaths.
Nghi Son officials are still investigating the cause of the fish kill.
