Virus at 2 Nova Scotia land-based fish facilities results in 600,000 salmon being killed

About 600,000 salmon smoltshad to be killed followingan outbreak in Februaryof infectious salmon anemiaat two land-based fish facilities in Nova Scotia.

Aquaculture Minister Keith Colwellsaid Thursdaythe two facilities are located close to each other, but wouldn't name them. "The virus is just in one location and they move fish from one facility to the other," he said.

The loss amounted to almost all of one company's fish stock, but wasn't as significant for the second.

There aren't any health concerns for humans as the virus only affects salmon, he said.

Colwellalso said it's unusual to have this kind of outbreak on land-based facilities.

"It's a real serious loss for the two companies that are involved, they're small companies, so we're very concerned about that,"Colwellsaid.

According to a statementissued by the province, the fish-farm operators reported a concern to veterinarians who then conducted testing. Once the tests confirmed the virus, the sites were quarantined.

The province saidthe virus is native to Atlantic Canada and was first detected here in 1996. Prior to these incidents, the most recent disease-causing version of the virus in Nova Scotia was in 2012 at a Cooke Aquaculture site in Shelburne County.

In 2016, there were at least four separate incidents recorded in New Brunswick.

Colwellsaid the province wouldn't provide operators with financial assistance as that's not permitted under regulations.

CBC News requested comment from the Atlantic Canada Fish Farmers Association, but it has notresponded.
