Here’s how scientists discovered salmon that need less food to grow

Norwegian researchers have identified young salmon that can be farmed using less feed than their not-as-efficient brethren.

Ecological food to have longer life

Have you heard about the method that keeps salmon fresh for a whole month, without the use of chemicals?

New weapons in the battle against salmon lice

The best weapon in the battle against salmon lice in the Norwegian aquaculture industry has proved to be the use of what are called “cleaner fish”, fish that eat salmon lice. But these fish often die during breeding. Now, researchers have found a way to help the young fish survive.

Salmon lice have always been a natural parasite on wild salmonids. However, during the last years the infestation of salmon lice has increased on wild salmonids causing negative consequences – and especially for sea trout.

Mutated salmon louse DNA spread throughout the North Atlantic in 11 years or less

A recent study has demonstrated that genetic changes giving the salmon louse partial resistance towards one of the most commonly used delousing chemicals in marine aquaculture (emamectin benzoate/Slice) have spread to salmon lice in the entire North Atlantic in a maximum of just 11 years.

Tailor-made medicine to fight the salmon louse

The salmon louse has become ever more resistant to drugs. The Sea Lice Research Centre in Bergen works to find new solutions to fight it.

Wild salmon can adapt to climate change

Atlantic salmon are more capable of withstanding temperature changes than scientists had thought.

Salmon genome fully sequenced

After five years of international research cooperation between Norway, Chile and Canada, the Atlantic salmon’s genetic material has been fully sequenced.

The fish feed of the future grows in the woods

Yeast produced using chips from Norwegian spruce trees and bacterial meal grown on natural gas from the North Sea become high quality proteins for farmed fish.

Not just one type of salmon louse

New results show that there are two sub-species of salmon lice. This fact may be vital to the development of new lice treatments for salmon, since different sub-species don’t necessarily react in the same way to medications.
