Being happy at work relies on more what’s happening in the workplace itself. It relies on good physical, emotional and mental health too.
We believe in farming our salmon out in the Scottish elements, in conditions that replicate their natural habitat as closely as possible.
That means deep, cold sea lochs and seas with fast-flowing, well-oxygenated waters and strong currents. But it also means dealing with the different challenges that the marine environment can present.
Below, you’ll find details of how we are performing with regards to the key challenge of sea lice, as well as our record on fish survival.
Sea lice occur naturally in the marine environment and affect both wild and farmed salmon.
Whilst we can’t stop sea lice from occurring, it is our responsibility as farmers to do everything we can to help keep levels to a minimum.
Recent years have seen us invest on a multi-million pound scale in new sea lice controls – the majority of them non-medicinal – with encouraging results at many of our farms.
We report sea lice figures, based on the number of average females, on a weekly basis, one week in arrears, to Marine Scotland’s Fish Health Inspectorate.

Whilst our driving force is the health, welfare and survivability of our stocks, every animal population experiences a level of mortalities.
Wild salmon is now thought to have an average survival rate of less than five per cent due to the challenges of the natural environment; challenges that can also affect farmed salmon.
However with attentive fish husbandry and responsive health management, we’re now seeing average end of crop survival rates of 83% (2022) and above amongst farmed stocks – our five-year average fish survival being 89% – and we’re not resting there.
With each new crop of fish, we’re looking for the lessons learned in order to increase our understanding, reduce fish mortalities and further enhance the survival rates of future crops.
We’re also sharing these same insights at sector level, as members of Scotland’s 10 Year Farmed Fish Health Framework.
For many years now, Scotland’s salmon farmers have reported survival rates to Marine Scotland. In 2018, we took the decision to voluntarily publish these rates publicly, making Scottish salmon the first farming sector in the UK to provide this level of transparency.
We report fish survival on a monthly basis, once month in arrears, and you can view this data in two ways via two different:
