Chilean environmental authority SMA is warning salmon growout sites in the South American nation to be prepared in case of mass mortalities linked to the effects of the El Niño phenomenon.

There are fears El Niño effects could impact southern Chile during the 2023/24 summer season.

Growout site bosses have been told to implement preventive measures to try to avoid and control the threat of algal blooms, which have proved devastating to the Chilean salmon industry in the past.
