The planktonic stages of the salmon louse ( Lepeophtheirus salmonis) are tolerant of end-of-century p CO 2 concentrations
The copepod Lepeophtheirus salmonis is an obligate ectoparasite of salmonids. Salmon lice are major pests in salmon aquaculture and due to its economic impact Lepeophtheirus salmonis is one of the most well studied species of marine parasite. However, there is limited understanding of how increased...
