Salmones Pacific Star, a division of Salmones Austral, has been hit by an algal bloom at one of its production sites in Chile's Aysen region, leading to the loss of 200,000 salmon, the second incident to occur in the country within a week.

It is estimated the incident at the Centro Ester growout site will cost the company approximately $1.15 million (€1.01 million).

Mortalities are expected to reach 25 percent of fish kept at the production site, the company said.
