The commitment was made during a working session between Deputy Prime Minister Trinh Đinh Dung as he inspected several fish farms in Ky Anh Commune of central Ha Tinh Province.

During the inspection, Dung asked the four provinces of Ha Tinh, Quang Binh, Quang Tri and Thua Thien–Hue to make accurate calculations of the damage and loss caused by the massive fish death event so that adequate support could be given to local residents.

He also asked the Ministry of Agriculture and Rural Development (MARD) to inspect the waste water treatment systems of large firms and production units.

Over the past two weeks, it is estimated that some 15 tonnes of natural fish and 2 tonnes of farmed fish have died in Ha Tinh Province. Meanwhile in Thua Thien–Hue Province, some 30 tonnes of natural fish died and were washed up on beaches.

On April 24, a dead whale was found on a beach in central Thua Thien-Hue Province. 

All along the coast of Thua Thien-Hue dead fish were found and many fish farms along the coast that use ocean water for aquaculture in Lang Co Bay have also been effected.  

Nguyen Huynh Ky, who runs a fish farm in Lang Co Town, told a Vietnamnews reporter that two thirds of his fish had died without any symptoms of disease. He suspects that the ocean water was somehow poisoned.

Meanwhile, fishermen along coast of Phu Vang and Quang Dien said they had returned to shore with empty nets from recent fishing trips in local waters.

Officials from the ministries of the environment, agriculture and public security have arrived at the affected areas to investigate the incident.
