Removing salmon lice the natural way

In 2015 Bakkafrost began bathing salmon in freshwater as an alternative to replace chemical treatment of sea-lice.

Bathing salmon in freshwater is to imitate nature, where the wild salmon head up the freshwater streams to spawn and at the same time cleanses itself for sea-lice.

Bakkafrost uses its new wellboat "Hans á Bakka" for this purpose. When the boat was designed Bakkafrost decided to make the necessary changes to the vessel design. The extra costs amounted to an investment of around NOK 20 million.

The salmon swim into a freshwater tank in the wellboat before entering the seawater again. This  treatment has been succesful with a efficiency of up to 99.1%.

With this invention Bakkafrost haven't just managed to combat the big lice. The louse has nine stages, and with the freshwater treatment they have succeeded in eliminating up toward 99 percent of the lice in all nine stages.

Another advantage of this treatment is that the salmon remain in good condition during and after the treatment. Salmon start eating immediately after they return to the cages after the treatment. This is not seen in connection with most of the other treatments the salmon industry have employed.

Bakkafrost hasn't utilized any medicines after Hans a Bakka commenced the treatment procedure!
