==Introduction==
[[File:Argulus.jpg|250px|thumb|right|'''Fish Louse (''Argulus sp.'') attached to the skin of a fish ''']]
The '''fish louse''' is a '''metazoan parasite''' of '''freshwater fish'''.
The louse has a sharp stylet along the ventral midline that it uses to pierce the skin of the fish. It then injects digestive
enzymes into the surrounding tissues and then feeds on the digested bodily fluids.
A consequence of this is '''localised inflammation and irritation''' of the skin, which is a welfare concern. It also allows secondary '''opportunistic infections''' to develop, and can transit '''bacterial and viral infections''' directly.
==Diagnosis==
The louse can be seen with the '''naked eye''', growing up to '''7 mm''' in length.
==Treatment==
Infestations can be treated with an '''increase in water salinity'''. If this is ineffective '''organophosphates''' or '''chitin inhibitors''' can be used.
