Ervik Laks og Ørret (Ervik Salmon and Trout) lost about 80,000 salmon after delousing them with hydrogen peroxide aboard the Gåsø Viking, according to Norwegian Food Safety Authority (FSA) documents obtained by IntraFish.

The company said the incident happened during the relocation of 200,000 fish from the Raskjæret site to Aursøyva in early May, where there were to be divided between two cages.
