"Fish lice" of the genus Argulus (suborder Branchiura) are Common parasites of freshwater fish, and may occur on frogs and salamanders. Argulids often cause severe mortality of fish in farm ponds, and sometimes in natural waters. Because information on life cycles, ecology, and host specificity is incomplete only a generalized account can be given.
