Restlessness as to ISA outbreak, despite government’s explanations
Thursday, April 11, 2013, 01:10 (GMT + 9)
After the National Fisheries and Aquaculture Service (Sernapesca) confirmed the detection of an outbreak of infectious salmon anemia (ISA) in a fish farm belonging to the company Los Fiordos, in the Aysen region, the infected cage was harvested.
The virus was detected in a cage of the Garrao farming centre, where there were about 20,000 salmon specimens.
The authority is considering the possibility of removing all the fish from the centre, amounting to about 930,000 so as to prevent the spread horizontally, Diario Financiero reported.
Sernapesca has the authority to require the "elimination" of the fish, which only means that they must be removed from the water. For its part, Los Fiordos can harvest and market the salmon showing suitable sanitary conditions.
The company informed that "as a precautionary measure it has decided to harvest one of their cages in Garrao Centre, 18D district, Melinka area, beforehand, and in coordination with the relevant authority before the eventual presence of ISA virus."
Besides, the firm pointed out that "it is important to note" that the suspicion "has not been confirmed by the laboratory yet."
The company says it acted "conservatively to minimize health risks and remove any ISA trace in the biomass."
Once the test results are available, it will be possible to confirm whether there is ISA or not.
All the producers have already been informed about it to help maximize their biosecurity measures.
Meanwhile, the head of the Undersecretariat of Fisheries and Aquaculture (Subpesca), Pablo Galilea, stated "the situation was expected given that the ISA virus has not been eradicated from the environment but it has been possible to control it."
"What is relevant is that the monitoring system has proved capable of detecting the onset early in isolated cases that can be controlled before causing the devastating effects that occurred years ago," stressed the undersecretary.
Sernapesca was also in charge of monitoring the centre of Los Fiordos and all the district centres in order to rule out other cases in the area.
Despite the reassurances coming from Los Fiordos and from government agencies, the news had a negative impact on the Stock. The market fears were reflected in a collapse of the shares of the salmon firms on Tuesday, and the index that measures the performance of the sector fell 6 per cent in a day.
