What makes us organic?

Organic Sea Harvest is the only salmon farmer in Scotland to focus solely on producing the finest organic salmon, with both sea sites officially certified as organic by the UK Soil Association.

Organic Certification

We are registered with the UK Soil Association, the UK's leading membership charity campaigning for healthy, humane and sustainable food, farming and land use. We follow a strict set of rules and regulations laid out by S.A which allow us to market our product as organic. Furthermore, we aim to go above and beyond these statutory requirements through technical discussions on how the standards can be improved between generations (i.e each salmon "cycle") - providing information on best practice with an overall aim of maximizing the quality of life for our fish at all times.


Our deep, exposed locations are hand picked to create the best conditions for our fish and protect the environment from harm. The clear, open waters of North East Skye are perfect for the development of our organic salmon. High flow/water exchange rates, stable temperatures, salinity and dissolved oxygen levels all play a vital role. These conditions all help to safeguard the livestock of OSH from unfavourable environmental and biological conditions as the seasons change and our fish develop from smolts through to marketable salmon.

The wide dispersal of nutrient rich discharge (in the form of fish faeces) from our sites aids the environmental assimilation of our inputs. When operated from a balanced perspective, fish farm discharge may actually stimulate the surrounding ecosystems by supporting food chains - directly feeding benthic invertebrate species, through to fish, then marine bird and mammal populations.

OSH periodically employs third parties to carry out benthic surveys, ensuring that our farming operations comply with statutory requirements and that fish production in these locations does not come at the expense of local biodiversity. 

Stocking Density

The cages at the OSH sea sites have a maximum stocking density of 10kg per m3 - this equates to 99-99.9% water and only 0.1-1% fish, maximising the animals’ freedom to grow and thrive during the production cycle. Furthermore, these lower stocking densities reduce the transmission rates of salmon lice (and non-specific sea lice) between our livestock. This in turn, reduces the likelihood of needing to treat the fish for parasite infestations.

Our Fish

A strict 100% organic diet means that the feed our fish eat doesn't contain GMO's (Genetically Modified Organisms) or artificial preservatives. We prefer to use the highest proportion of marine ingredients available to us in the fish's diet - working in close partnership with our dedicated organic fish feed supplier.  This helps to maintain high levels of omega 3 & 6 that you find naturally in salmon populations, whilst also benefiting our consumers health, and allows us create an end product as close to a wild salmon as we can get.
