Statistical presentation

Aquaculture, also known as aquafariming, refers to the farming of aquatic (freshwater or saltwater organisms, such as fish, molluscs, crustaceans, echinoderms, and plants, under controlled conditions. Aquaculture implies some form of intervention in the natural rearing process to enchance production, including regular stocking, feeding and protection from predators. Farming also implies individual or corporate ownership of, or contractual rights to the stock being culitivated. 

Classification system:
The following variables are recorded in all tables: 

  • Reference year
  • National and regional level
  • Species or species group

Statistical unit:
The basic statistical units are companies or individual holder of a permit for aquaculture. However, presented statistics is aggregated and available at:

  • National level
  • Regional level
    • Troms and Finnmark
    • Nordland
    • Trøndelag
    • Møre and Romsdal
    • Vestland
    • Rogaland
    • Other regions

Staistical population:
All active commercial, research, education, and development licenses for aquaculture with production any time during the reference year.

Reference area:
Production at land or in sea (coastal and offshore) in Norway.

Coverage - Time:
Data for aquaculture production for Atlantic salmon, rainbow trout and trout are available since 1971. However, more variables are available now, than when the collection of data started in 1971. In 1989 aquaculture production of other fish species, molluscs, crustaceans, echinoderms was included in the statistics. In 2015 aquaculture production of algae was included.


Volume is expressed in average kg per fish, tonnes live weight/wet weight or numbers of individuals (1000 numbers).
Value is expressed in 1000 NOK.
