Over 100 tons of fish died in Tri An Lake in Dong Nai province.

On May 31st, authorities in Tri An ward ( Dong Nai city) continued their efforts to assist residents in collecting and removing dead fish floating on cages and rafts in Tri An lake to minimize water pollution.

According to a reporter from the Vietnam News Agency (TTXVN), on the morning of May 31, hundreds of local residents, police officers, military personnel , and forest rangers were working to remove the carcasses of dead fish floating on Tri An Lake.

In the fish cages, thousands of catfish, carp, grass carp, tilapia, and other fish raised by local people have died, floating on the water's surface. The dead fish are densely packed, emitting a foul odor and seriously affecting the environment and the lives of the surrounding residents.

Some affected fish farmers said that the mass fish deaths began on the evening of May 29th, following prolonged heavy rains. Within a short period, farmed fish died en masse, resulting in almost total losses for many cages and rafts.

Mr. Nguyen Van Manh, residing in Tri An ward, Dong Nai city, said that his family mainly raised catfish and grass carp this time. Within just two days, all of his family's fish died completely. "More than 65 tons of fish, which were almost ready for harvest, suddenly died all at once, leaving us no time to react," Mr. Nguyen Van Manh shared.

Similarly, Mr. Nguyen Tuan Anh, residing in Trang Bom ward, Dong Nai city, said that this was the first year his family had invested in cage fish farming on Tri An Lake. Since October 2025, he had stocked over 10 tons of various types of fish and was only a short time away from harvesting. However, after a heavy and prolonged rainstorm overnight, all the fish in the cages suddenly died en masse, causing significant economic losses for his family.

Immediately after the incident was reported, local authorities coordinated with relevant agencies to inspect the scene and organize the collection and disposal of dead fish to minimize environmental pollution.

Ms. Nguyen Thi Dung, Chairwoman of the People's Committee of Tri An Ward, Dong Nai City, said that immediately after receiving the information, the ward mobilized specialized departments, military forces, local security forces, neighborhood committees, and forest rangers from the Dong Nai Cultural and Natural Reserve to assist people in collecting the dead fish and bringing them ashore to protect the environment of Tri An Lake.

At the same time, the local authorities reported the incident to the Department of Agriculture and Environment of Dong Nai City, requesting that specialists be sent to the scene to collect fish and water samples for testing to verify and clarify the cause. Initially, the cause may be due to heavy rains at the beginning of the season causing a sudden change in the water environment, leading to mass fish deaths.

Local authorities are currently monitoring developments, assisting residents in overcoming the damage, reporting and recommending solutions to the Dong Nai City People's Committee to support affected residents; at the same time, they advise people to proactively take measures to respond to and minimize damage in adverse weather conditions.
