The salmon louse is, as previously, one of the most significant threats to the aquaculture industry. As many fish die or are injured during de-licing treatments, this represents a serious health and welfare issue. Of the viral diseases, pancreas disease (PD) and infectious salmon anaemia (ISA) are the most significant. In addition has the bacteriale desease Yersiniosis become an increased challenge in mid-Norway.
