A record 62.7 million salmon died in Norwegian netpens last year, according to a report released this week by Norwegian officials.

The number of salmon deaths in Norway last year was 6 million greater than during the previous year, the Norwegian Veterinary Institute said.

The mortality rate in the country’s salmon farms was 16.7 percent in 2023, up from 16.1 percent the previous year.

“We are not seeing a decrease in mortality rates,” Edgar Brun, director of the Norwegian Veterinary Institute's fish health department, said in a statement.
