The agency reported that six farms, including three belonging to Blumar, one to Salmones Austral and one to Aquachile, in addition to a site owned by Mowi Chile, have activated contingency plans for mass mortality associated with oxygen shortage, an event, the agency said, “that has no direct relationship with the contingency for harmful microalgae”.

As notified by the owners of the companies, the biomass affected (mortality) as of Wednesday 12, was 2,666 tonnes, from which 2,177 tonnes (82 per cent) have been removed.

Cristian Hudson, Regional Director of Sernapesca Aysén, commented, “For our part, as Sernapesca, we will continue to monitor each of the crop neighborhoods that have been affected, in order to verify and permanently monitor the execution of the activities committed in the action plans, until the end of the mortality event.”

“We will continue to carry out this monitoring in each of the centers, through satellite, remote monitoring systems, information cross checking and mainly with the presence of our officials in the field, keeping us alert to climate changes that could modify the current environmental condition of the affected areas.”

According to the latest phytoplankton monitoring reports, microalgae concentrations have been observed to have been decreasing in recent days.
