Cermaq Chile could be facing a fine of up €4 million ($4.3 million) after being charged with overproducing salmon at its Estero Navarro growout site in the South American nation's southern Magallanes region.

The company allegedly exceeded by 782 metric tons the amount it is annually allowed to produce at the site in the protected Kawesqar National Reserve between May 2017 and June 2019.
