Kunnskapsbasert forvaltning og dilemmaer knyttet til usikkerhet

Major value conflicts have been played out in the media about farmed salmon in Norway. One of the main controversies is whether salmon lice from aquaculture pens significantly affect the survival of wild salmon at stock level. Research related to this topic, which is key to knowledge-based management of aquaculture in Norway, has been criticized. The quality of this research has been claimed to be low and not applicable, and even claims of misconduct have been expressed. Besides conflicting interests, we argue that uncertainty is the core of the controversy. In this chapter we look at statements in selected texts from articles, reports and the media which can be linked to uncertainty and quality in research related to the effects of salmon lice. We discuss these statements in terms of qualitative aspects of uncertainty in knowledge. Further, we discuss the roles of these uncertainties in terms of selected principles within research ethics: in communication of uncertainty, the precautionary principle and quality of research.
