Chilean salmon farmer must harvest or remove infected fish.
On Monday, it was reported that the fishing and aquaculture authority Sernapesca suspected an ISA outbreak at a Cultivos Yadran site, located in Aysén, southern Chile.
In a statement, authorities have now confirmed the detection of the virus.
The salmon farmer has been ordered to execute as soon as possible the harvest and/or elimination of positive-tested fish in the infected cage.
Sernapesca consequently has informed other salmon farmers of this situation and have implemented remote monitoring measures in the area to prevent the spread of the disease to other sites.
Cultivos Yadran produces around 55,000 tonnes of salmon a year.
