Salmon louse - Wikipedia
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. [5] Each phase comprises one or two life stages (not shown here). Scaled to size.
What Are Sea Lice?, Alaska Department of Fish and Game
Sea lice are common on adult salmon, and fall off as the salmon return to freshwater streams to spawn. This insures there are no surviving sea lice where the juvenile salmon outmigrate in the spring. Sea lice have been around as long as salmon but have only recently become an issue.
Sea louse - Wikipedia
Sea lice die and fall off anadromous fish such as salmonids when they return to fresh water. Atlantic salmon return and travel upstream in the fall to reproduce, while the smolts do not return to salt water until the next spring.
