Authorities are investigating and numbers could be much larger if virus is detected at sea site.
Last week, SalmonBusiness reported that Chilean fishing and aquaculture authorities Sernapesca discovered a positive diagnostic analysis of ISA at one of Granja Marina Tornagaleones’ (Marine Farm) sites.
The salmon farmer notified authorities last Wednesday about a site in the Aysén Region, southern Chile.
Now, in a press release, Sernapesca reports that now the entirety of the smolt on site have to be destroyed.
The virus was detected in some of the sites containing smolts.
“By virtue of this, veterinarians of the service carried out an inspection to the salmon farm in order to determine the sanitary state of the fish that are contained there, this fish farm has about 800 thousand fish contained,” explained the regional director of Sernapesca, Cristian Hudson told Cooperativa.
Due to the detection, authorities will carry out surveillance across all Atlantic salmon farming sites in the area to assess the situation of the fish in the area.
The publication added that final number of fish that need to be culled could be much higher as infected salmon may have been transferred to salt water site in the Los Lagos region.
