The scientists say that large-scale mortalities are now happening more frequently and at a larger scale than ever before.

They argue that warmer seas and greater reliance on technology are contributing to the rise in deaths.

This global assessment looked at salmon deaths in some leading producers, including Norway, the UK and Canada.

Salmon farming has come a long way since the fish were first grown commercially in cages in Norway in the 1960s. The industry has expanded rapidly in recent decades, with around 70% of salmon eaten around the world now coming from farms.
