Temperature affects settlement success of ectoparasitic salmon lice ( Lepeophtheirus salmonis) and impacts the immune and stress response of Atlantic salmon ( Salmo salar)
Abstract In this study, the effect of temperature on Atlantic salmon ( Salmo salar ) stress and immune response to the ectoparasitic salmon lice ( Lepeophtheirus salmonis ) was investigated. We found that infestation affected the expression of several immune and wound healing transcripts in the skin...
