Monthly mortality data published by Salmon Scotland illustrates the scale of death and disease on Scottish salmon farms - data is published online up to October 2021:
Scottish Salmon Watch has trawled through all the monthly reports during 2021 and of the 104 salmon farms harvested up to October the average cummulative mortality is 15.7% with The Scottish Salmon Company (21.2%) and Loch Duart (18.9%) the worst companies thus far during 2021:
Is there a simple reason why some salmon farming companies have higher mortality rates than others? Why is @salmon_scottish & @LochDuartSalmon double that of @WesterRossSalmo & @CookeScotland? https://t.co/YP7xPmmrFt @ScotlandSalmon @MowiScotlandLtd @GriegShetland @scotseafarms pic.twitter.com/ToPcn8BFdD

Congratulations @MowiScotlandLtd who report @ScotlandSalmon an average mortality rate of 12.6% in 2021 (data up to Oct). That's a fall from 23.6% in 2020 - but still a quarter of all fish are dying at some sites like Torridon, Sconser Quarry & Colonsay! https://t.co/YP7xPmmrFt pic.twitter.com/loaltPklPq

The average mortality rate for the salmon farming sector was 19.7% in 2020 out of 99 sites harvested (according to cummulative mortality data published online by Salmon Scotland):
A big slap on the back to all salmon farmers in Scotland for reducing the mortality rate from 19.7% in 2020 to 15.7% in 2021 (data up to October @ScotlandSalmon) @salmon_scottish @scotseafarms @MowiScotlandLtd @GriegShetland @LochDuartSalmon @CookeScotland https://t.co/YP7xPmmrFt pic.twitter.com/WxqVmT2WEG

Here's the definition of 'cummulative mortality' from Salmon Scotland:
Some salmon farms are fallowed before they are harvested with farmed salmon stock moved to another farm - here's cases in 2020 and 2021 as reported by Salmon Scotland:
The Scottish Government published data in September 2021 on survival of smolt year classes with the latest data available for 2018 detailing a survival of 75.9% (i.e. mortality of 24.1%):
Survival (i.e. mortality) rates differed across Scotland with Shetland reporting only 55.2% survival (i.e. 44.8% mortality) of the 2018 year class:
Scottish Salmon Watch reported on Friday (10 December 2021):
