Norwegian aquaculture focuses on sustainability and quality

From fresh water to the sea, in the deep fjords of Northern Norway. Salmon farming in the Nordic country takes place through a safe and sustainable aquaculture process with strict regulations on certification and facility management.

Salmon live in the sea but reproduce in fresh water. After fertilization of the eggs, the embryo is kept in fresh water for 60 days until it hatches. Then, it grows for 16 months when it can be transferred to the sea. Here it is kept in floating cages for about 14-22 months until it reaches a weight of between four and six kilograms.

The breeding facilities are located in deep fjords, with a natural flow of cold, oxygen-rich seawater, ideal environment for Atlantic salmon. Arrived at five or six kg in weight, it is taken to a factory on the island of Lovund, 30 km from the mainland. Hence, finally, worldwide delivery in less than 48 hours after being taken from the ocean after careful quality controls.

According to Norwegian legislation, salmon farming must respect local ecosystems. Each aquaculture facility is managed sustainably and ensures adequate space for fish to move in a clean environment: in these plants, in fact, 2.5% of the volume is represented by fish and 97.5% by water. The salmon are fed only high quality feed and since 1987 there has been a 99% reduction in the use of antibiotics.

Farms can only operate under license which is obtained by respecting very strict criteria: they must be in the open sea, in the cold and clear waters of the fjords, away from the routes of maritime traffic. Furthermore, they must observe a rest period at the end of each cycle during which the seabed is monitored with the aim of preserving the natural ecosystem. The number of installations is limited: there may be less than 750 for over 28,000 km of coastline.
