Semi-closed Aquaculture

For decades conventional salmon farms have used open net pens. This proven method has produced healthy, low-carbon protein for Scotland and the world for decades. Famers using conventional open net pens must manage and mitigate several challenges. These include fish health issues such as sea lice, environmental disruption, and predator interaction such as from seals.  

At Loch Long Salmon we want to take a new approach and believe prevention is better than cure. This will be achieved by using semi-closed farming systems. These systems have been deployed in Norway for over 10 years but Loch Long Salmon will be the first company to use them in Scotland.

Protecting the environment & enhancing fish welfare

Fish are healthiest when left undisturbed in the water.  Loch Long Salmon’s semi-closed systems prevent sea lice from entering the farming environment, removing the need for sea lice control.  This means that our fish will be healthier and enjoy higher welfare than salmon grown on a conventional open net farm, and no sea lice in the enclosures removes any risk of impact on wild fish. 

The water quality, flow rate, oxygen saturation and temperature regulation means our farms will grow healthier fish in fewer farming enclosures reducing visual impact and space requirements. 

In addition, the impermeable outer barrier which surrounds each net collects over 85% of the solid waste in the form of uneaten food and fish waste.  It will be gathered, removed, processed and turned into a green resource, reducing our environmental impact and contributing to the circular economy. 

Our Farms

Loch Long Salmon submitted the planning application for our first farm, Beinn Reithe in Loch Long, in November 2021.

We are investigating other sites for the future and will provide more information as soon as possible.
