An increasing net cage farming of salmonids in Norway are leading to increased production of infective salmon louse (Lepeophtheirus salmonis) larvae in coastal areas. One of the most vulnerable salmonids for salmon lice ...

Formålet med denne undersøkelsen er å overvåke utviklingen av bestandene av laks og sjøør-ret i Auravassdraget. Resultatene skal danne grunnlag for å evaluere de tiltakene som er gjen-nomført som kompensasjon for negative ...

Parasites can, in theory, have large impacts on the survival of fish populations. One method to evaluate such impacts on anadromous species is to apply manipulative field experiments in which parallel groups of antiparasitically ...

Consistent individual differences in behavior have been demonstrated for many animals, but there are few studies of consequences of such repeated behavior in the wild. We tested consistency in migration timing to and from ...

For successful evaluation of the overall effects of salmon louse infestation on brown trout population dynamics, it is crucial to have a realistic understanding of how lice infestation distributions are generated and how ...

The parasitic salmon louse, and its resistance to chemical delousing agents, represents one of the largest challenges to the salmon aquaculture industry. We genotyped lice sampled from wild salmon and sea trout throughout ...
