QUẢNG NGÃI — Bacterial infection has caused the mass deaths of grouper fishes being bred in cages in the central Quảng Ngãi Province’s Bình Sơn District, according to the provincial animal husbandry and veterinary department.

The announcement was made by department head Nguyễn Đình Tuấn on Wednesday.

The incident took place at the end of July in Bình Thuận Commune’s Tuyết Diêm 1 village, where locals found grouper fishes in many cages dead and floating in the water. By August 3, the number of deaths had spread to the nearby cages, too. 

The fishes that died from the infection had been bred for two to five months.

Department officials had collected fish and water samples for tests and checked the salinity, oxygen, NH3 and pH levels of the water. Results showed that NH3 levels exceeded the standard level and some of the fishes got infected by bacteria such as photobacterium damselae and vibrio parahaemolyticus.

The veterinary staff and local authorities have advised farmers to collect the dead fishes for burial and take steps to improve oxygen level in the cages. — VNS
