Policy: Cleaner fish

Cleaner fish policy

Owner/approver: COO of Farming 

Valid from: 2022-03-29



In order to ensure the best possible results from using cleaner fish as a means of biological lice control, we need proper routines and close follow-up. We focus on proper care to safeguard the health and welfare of the cleaner fish in every part of the value chain. We believe that this allows the cleaner fish to act as an efficient lice-eater.

The policy framework has strong support throughout the organisation, and its principles are reflected in both actions and established procedures. We will gradually achieve our goals by means of systematic and continuous improvements.

Valid for

This policy applies to all the Group's farming operations.


Cleaner fish: Wild-caught or farmed species in the Labridae family or farmed wrasse (Cyclopterus lumpus) used for biological delousing.

Biological delousing: Combating lice in marine production of salmon and trout using fish species that eat lice.


Framework and principles

The framework and principles follow, as a minimum, the provisions of the Norwegian Animal Welfare Act and the Regulations concerning aquaculture operations. We do our utmost to ensure proper welfare by:

  • Offering feed with customised nutritional contents

We also strive to avoid the use of more cleaner fish than deemed necessary to maintain good control of lice.
