Lepeophtheirus salmonis
also known as: sea lice, copepod, salmon louse
|
Lepeophtheirus is of two common species of parasitic copepods encountered in salmonids in the Pacific Northwest (see also Salmincola sp.). Lepeophtheirus is a marine species, most commonly found on gills of salmonids in estuaries or caught on the coast. By the time returning adults make it upriver, most of the copepods will have dropped off and died. Copepods have caused controvertial impacts on fish in British Columbia, associated with netpen aquaculture. Small fish are more prone to health impacts than larger fish. |
