The planktonic stages of the salmon louse ( Lepeophtheirus salmonis) are tolerant of end-of-century p CO2 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 Lepeoph- theirus salmonis is one of the most well studied species of marine parasite. However, there is limited understanding of how increase...
