An estimated 1,000 tonnes of oyster have died over the past five days since fishermen made the first discovery last Monday.
It’s the first major loss of harvest that locals have seen in 20 years.
Tran Thi Xi, 54, who lost 3 tonnes of oyster, said polluted water would be a main reason for shellfish dying en masse.
“Oysters rarely die of an illness. Water at the bay would likely have been polluted by waste from Tho Quang seafood processing zone which is just 1km away,” Xi said.
