Candidate genes for monitoring hydrogen peroxide resistance in the salmon louse, Lepeophtheirus salmonis.

ABSTRACT:

Background

Hydrogen peroxide (H₂O₂) is one of the delousing agents used to control sea lice infestations in salmonid aquaculture. However, some Lepeophtheirus salmonis populations have developed resistance towards H₂O₂. An increased gene expression and activity of catalase, an enzyme that breaks down H₂O₂, have been detected in resistant lice, being therefore introduced as a resistance marker in the salmon industry. In the present study the aim was to validate the use of catalase expression as a marker and to identify new candidate genes as additional markers to catalase, related to H₂O₂ resistance in L. salmonis.

Methods

A sensitive and an H₂O₂ resistant laboratory
