Grieg Seafood Newfoundland reported a case of Infectious Salmon Anemia (ISA) in one Atlantic salmon parr at its Marystown hatchery, in Canada.  The case was detected during routine health inspections. The impacted tank contains 118,000 individuals.

“More analysis is needed to determine whether the fish is infected or not. The detection has not been confirmed by regulatory agencies. Further testing is ongoing in cooperation with veterinarians from the province, with independent analysis to be provided from accredited labs. All precautionary infection control measures are implemented, in line with regulations,” the company said.

The company said that the fish in question was recently vaccinated against ISA. Current stock are not showing any symptoms of disease, nor have there been any instances of increased mortality.
