A review on how Atlantic salmon (Salmo salar) farming in Norway is influenced by the salmon louse (Lepeophteirus salmonis

Abstract

The salmon louse, Lepeophtheirus salmonis, is considered the biggest parasitological problem in Norwegian aquaculture today, causing not only damage to its hosts but also huge financial costs in the form of treatments and preventive measures. In addition one must consider the impact the increasing number of parasites, and chemicals aimed at killing it, may have on wild marine species and the environment. Drug resistance is becoming a serious problem and huge efforts are put towards developing new and improved methods to fight salmon lice infestations.
