The impact of Sea louse (Lepeophtheirus salmonis) on animal welfare in Norwegian farmed Atlantic salmon (Salmo salar L.): regulation and literature review

Abstract

Norway is the largest producer of farmed Atlantic salmon (Salmo salar L.) and the industry continues to expand. Since the beginning of the aquaculture industry in Norway, the salmon louse (Lepeophtheirus salmonis) has been a problem for the fish welfare and is known to be one of the largest threats to Norwegian Atlantic salmon. Norway is known to have a strong governmental control and the aquaculture industry is regulated in a complex way including several laws from different departments.
