Nearly a million fish were on site.

Chilean aquaculture and fishing authority Sernapesca writes that salmon farmer Invermar notified it about “sudden and massive” salmon mortality at one of its coho sites in the Los Lagos region, southern Chile.

The number of fish that died is still being counted, but 937,257 salmon of approximately 780 grams were at the site. 861,000 have now been counted as dead.

Authorities confirmed to Fish Farming Expert that it investigated and confirmed the salmon died from an algae bloom outbreak of Cochlodinium sp. The dead fish have been removed.

To date, no other salmon farms nearby have reported any with abnormal mortality due to that reason.
