Abstract
Fish pathologies caused by parasitic crustaceans lead to mass mortality in affected populations. Called popular, fish lice, these crustaceans have body adapted to parasitic life. Among others, the most common parasitosis in cultured fish is argulosis, ergasilosis, lerneosis and sinergasilosis. Argulosis, is the most common crustacean parasitosis, widespread in the world, common to many species of freshwater fish, marine and brackish water. All fish development stages are receptive to argulosis. Sodium chloride is widely used to control pests during the growth stage of fish, from alleviants to the adult fish. The difference in terms of lethal concentration of sodium chloride for the fish and for the parasites is not very large and for this reason it is necessary that, during the treatment, all general principles of therapy to be respected, particularly those relating to tolerance tests. This work has as main goal the establishment of optimal concentration of sodium chloride to treat argulosis in the case of beluga juveniles.

Key words: argulosis, sodium chloride, beluga juveniles
