Salmon louse infestations are a major cause for economic losses in the salmon aquaculture industry and production costs are increasing by roughly $480 million annually. Although parasites, such as Caligus rogercresseyi, can be treated with pesticides, resistance to pesticides continues to emerge. Researchers used Illumina sequencing technology to identify resistance markers in parasites, expression analysis to understand how the parasite metabolized a specific pesticide, as well as host identification. Such comprehensive data of processes between host and parasite, can better help us detect parasite’s resistance and safely use effective measures to eradicate and control infestations.
