Immunological response profiles to salmon lice infections in Atlantic salmon : modulation by nutrition and selective breeding
Infections with the salmon louse Lepeophtheirus salmonis (L. salmonis) represent one of the most important limitations to sustainable Atlantic salmon (Salmo salar) farming today. The parasite exerts negative impacts on health, growth and welfare of farmed fish, and there are concerns of the impact o...
