Sea Louse
Sea lice (singular: sea louse) are copepods (small crustaceans) of the family Caligidae within the order Siphonostomatoida. They are marine ectoparasites (external parasites) that feed on the mucus, epidermal tissue, and blood of host fish. The roughly 559 species in 37 genera include around 162 '' Lepeophtheirus'' and 268 ''Caligus'' species. The genera ''Lepeophtheirus'' and ''Caligus'' parasitize marine fish, in particular those species that have been recorded on farmed salmon. ''Lepeophtheirus salmonis'' and various ''Caligus'' species are adapted to salt water and are major ectoparasites of farmed and wild Atlantic salmon. Several antiparasitic drugs have been developed for control purposes. ''L. salmonis'' is the best understood in the areas of its biology and interactions with its salmon host. ''Caligus rogercresseyi'' has become a major parasite of concern on salmon farms in Chile. Studies are under way to gain a better understanding of the parasite and the host-parasi ...

Salmon Louse
The salmon louse (''Lepeophtheirus salmonis'') is a species of copepod in the genus '' Lepeophtheirus''. It is a sea louse, a parasite living mostly on salmon, particularly on Pacific and Atlantic salmon and sea trout, but is also sometimes found on the three-spined stickleback. It feeds on the mucus, skin and blood of the fish."Sea Lice." Marine Institute. Marine Institute, n. d. Web. 10 Dec. 2013. . Once detached, they can be blown by wind across the surface of the sea, like plankton. When they encounter a suitable marine fish host, they adhere themselves to the skin, fins, or gills of the fish, and feed on the mucus or skin. Sea lice only affect fish and are not harmful to humans. Salmon lice are ectoparasites of salmon. In the 1980s, high levels of salmon lice were observed on pink salmon smolts. Salmon lice are found in the Pacific and Atlantic Oceans; they infect pink salmon, Atlantic salmon, and chum salmon. Life cycle Some research has occurred on the problems ...
