Dead fish have been found washing ashore Da Nang this week, with fishing mines suspected to be the killers.
Locals saw fish bodies scattered all over the beach from Thanh Khe to Xuan Thieu in Lien Chieu District around noon on Saturday.
Most of the dead fish were sardines, Dr. Vo Van Phu, a college lecturer in biology said when seeing their photos.
Fishers and rescuers believed fishing explosives were to blame for the mass deaths.
A local firm specialized in urban environment affairs has cleared the dead fish upon request by local authorities.
The volume of the dead fish amounted to 952kg, excluding what locals picked up themselves, the company said.

The municipal Department of Natural Resources and Environment has requested the Da Nang People's Committee to direct efforts to deter locals from using explosives in fishing, as it also believed the mass fish deaths were caused by fishing mines.
The department noted that the same phenomenon occured in November 2017.
Environmental officials took water samples from the beach for testing but no results have returned.
No waste discharge from nearby sources was detected, the officials confirmed.
The Department of Natural Resources and Environment has required officers to continue taking water samples for testing until Monday, noting personnel must be assigned to follow up on the fish deaths.
