Aquaculture Stewardship Council (ASC) is an independent, international non-profit organization that manages a certification and labeling program for resbonsible aquaculture. ASC's aquaculture standards include the environmental and social effects of aquaculture and a standard for salmon farming has been developed.


To meet requirements for safety, sustainability and openness, Gratanglaks works with several voluntary certifications. Through the certifications, we can document and improve our production of salmon. 

Here you will find reports in accordance with the ASC-standard from our locations that are or will be certified.

Location number 
Each facility has a unique location number that is used to identify registered facilities.

Maximum allowed biomass is a provision given by the authorities that states how much fish a facility can have at any given time.

Last release of salmon
At a facility, fish from the same generation are released. In principle all fish will then be ready for slaughter in approx. the same time.

ASC certification status
Status of the ASC approval of the site.

Listed diseases
The Norwegian Food Safety Authority has established a list of infectious diseases to prevent and combat infection in aquatic animals. The breeders are obliged to report to the Norwegian Food Safety Authority in the event of an unexplained increased mortality and in the event of detection or suspicion of listed diseases.

Salmon lice status

Each breeder is required to register lice on the facility. This is done by weekly counting the number of lice on the fish in each cage at each facility. The numbers are then reported to the Norwegian Food Safety Authority. Counting of lice helps the breeder to predict when a possible de-lice must take place so that the lice limits set by the authorities are not exceeded. The lice numbers are published on Barentswatch.

Other certifications 
Gratanglaks focuses on sustainability, food saftey and safety for employees. To ensure our customers that we maintain good routines, we have chosen to certify our facilities through, among other things, the ASC standard, Global GAP and Whole Foods Market.

Deviation between released and slaughtered fish
After slaughter, the number of released fish is compared with slaughtered fish.

Coordinated control og salmon lice 
To reduce the spread of salmon lice from facility to facility, the breeders cooperate across each other. This is done through a coordinated plan for control and combat of salmon lice. Read more here.

Mortality in birds or mammals
Birds and mammals that live around a facility can be damaged and in the worst case die from equipment associated with the facility. In that case, this must be reported with the species, date and cause. Most cases occur when birds get stuck in the net that is over the cage. This net is to protect the salmon from birds, but unfortunately there are some birds that get tangled up and are unable to get loose again.
