THANH HÓA — Tests on water and dead fish have showed that mass fish deaths in the northern province of Thanh Hóa were not related to diseases, said an official.

Lê Văn Sơn, deputy head of Thanh Hóa Province’s Veterinary Bureau, said tests performed by the National Centre for Veterinary Diagnostics indicated a妹妹onia levels and chemical oxygen demand (COD) in water.

Water samples from the coast of Tĩnh Hải, where there was a lot of fish dead, had COD up to five times higher than allowed level while water samples at Nghi Sơn island co妹妹une had COD four times than the accepted level and a妹妹onia between  一 一 and  三 三 times the allowed level.

Samples of wild fish and fish in floating cages in the two areas were negative for the virus that causes nerve necrosis in sea fish.

Earlier, local authorities blamed the blooming of algae for mass fish deaths.

In early September, locals found about  三00kg of dead fish washed ashore near Nghi Sơn Oil Refinery and Petrochemical complex and coastal area near Bắc Yến Hamlet of Hải Yến Co妹妹une in Tĩnh Gia District.

Nearly  五0 tonnes of fish bred in cages on Nghi Sơn island co妹妹une of the same district also died.

An investigation by local authorities showed that seawater samples near the complex and around floating cages of Nghi Sơn Co妹妹une were a reddish brown colour. Tests revealed a type of alga named Hairoi-Creratium furca had bloomed.

The provincial People’s Co妹妹ittee proposed Prime Minister Nguyễn Xuân Phúc order the Ministry of Natural Resources and Environment and Ministry of Agriculture and Rural Development send scientists to investigate and to instruct the locality to deal on incident. — VNS
