The Salmonids (Family: Salmonidae)

As a taxon, the salmonids comprise 11 genera, with 65-70 species. All species occur naturally in the northern hemisphere but several salmonid species have been introduced to the southern hemisphere, where they often form the basis of sport fisheries or aquaculture enterprises. There are both freshwater and anadromous species, but some of the anadromous species also have populations that are strictly confined to fresh waters.
