The effect of temperature on ability of Lepeophtheirus salmonis to infect and persist on Atlantic salmon (Salmo salar)
The salmon louse (Lepeophtheirus salmonis) is an ecologically and economically important parasite of salmonid fish. Temperature is a strong influencer of biological processes in salmon lice, with development rate increased at higher temperatures. The successful attachment of lice onto a host is also...
