The Ministry of Natural Resources and Environment (MoNRE) has just proposed Hanoi authorities to investigate the recent mass fish deaths at the West Lake, the largest lake in the city.

“Hanoi should consult domestic and international experts along with specialist agencies,” noted the ministry.
A large number of fish went belly up along the edge of the West Lake on July 9.
Director of the Hanoi Department of Construction Le Van Duc said that the phenomenon would be due to the prolonged hot weather.
25 tons of dead fish have been found until now, equal to merely one-tenth the amount of fish washed up in 2016, Duc noted.
Vo Tien Hung, director of Hanoi Water Drainage Company, said about 500 workers of the firm have involved in solving the mess on July 8-9.
Earlier in October 2016, 200 tons of dead fish washed up in West Lake followed by thousands of dead fish in Linh Dam Lake. The incident was then attributed to pollution and changes in the weather, said the city authority.
Hanoi has over 100 ponds and lakes scattered across the city, but many of them are polluted by sewage and rubbish.
