The Age of Sustainable Seafood

Clean Farming

Clean farming is avoiding negative impact on the ocean environment, that means no permanent benthic impacts on biodiversity, zero chemical release to sea from sea lice bath treatment, and co-production of non-fed species (e.g., seaweed) for utilisation of nutrients from suitable farms and on fallowed sites whenever possible.

Monitoring seabed and biodiversity

Nutrients from our salmon farms may have temporary impact on the biodiversity of the seabed under and on the adjacent area of the farm. This impact is reversed after harvesting. Monitoring the seabed and ensuring no irreversible impacts is part of regulations and certifications.

No chemicals into the ocean

Sea lice are naturally occurring in the ocean and may attach to our salmon and spread from there. This is causing use of chemical treatment of salmon. We use preventing measures as skirts and deep-sea feeding to avoid sea lice. When treatment is needed, we prioritise using non-medical forms such as clean water. Our goal is no chemicals into the ocean.

Waste management and recirculation of plastics

Plastics are used in our pens, feed pipes, ropes and much more. When these are shifted the optimal situation is recirculation, and replacement of new equipment also based on recirculation of material. We are not there yet, but together with our supplier and partners we are heading for 100% recirculation of plastic and waste.

Seaweed and co-production

Seaweed and clams are example of species depending on nutrients is the ocean and may utilise nutrients from salmon farming, capturing nitrogen, phosphate as well as carbon. This circular system may produce food, feed, and energy where the waste from salmon farming is the input in seaweed production. Cermaq engages in seaweed co-production in Norway and Canada

Avoiding feed spill

Feed ending outside our pens are costly as feed is the largest cost of farming. It may also impact biodiversity outside the farm.
We use cameras and other monitoring of the feeding and how our salmon eats, to minimise spill of feed. One pellet spilt is one pellet too much.

Healthy fish don’t spread disease

A healthy fish with high welfare performs better and has ultimately better quality. This is essential for the productivity and sustainability in our farming. Good health is primarily ensured through optimal nutrition, beneficial environment in the sea, and preventing measures as vaccines.
