Farmed salmon face a number of challenges, in the marine environment and at the hatchery/freshwater stage. The issue of sea lice has received a lot of public attention, and it continues to be a significant problem, but farmers also need to deal with gill health, especially amoebic gill disease (AGD); jellyfish and algal blooms; temperature-related stress; diseases such as infectious salmon anaemia (ISA); and mortality and welfare issues during treatment. At the hatchery stage, infections such as saprolegnia can also cause mortalities.

 

Overall, the issues are closely connected: warmer water can increase parasite and jellyfish risks; gill damage can make treatments more hazardous; and repeated handling can worsen welfare and mortality. Recent figures suggest improved survival rates salmon producers have no grounds for complacency.

 

In Fish Farmer’s webinar “Fish Health 2026”, in association with ScaleAQ, our panel of experts discusses the challenges, the lessons that have been learned over the past few years and the prospects for improving fish health and survival still further.
