Salvelinus. 

Salvelinus, commonly known as char, is a genus of freshwater fish within the family Salmonidae. Some species are anadromous, meaning they spend part of their adult life at sea but return to freshwater to spawn, with juveniles typically remaining there for one or two years before migrating.

This genus has a circumpolar distribution, occurring across the cold and temperate waters of the Northern Hemisphere. Most char species inhabit cold, clear lakes and rivers, and are easily recognized by their dark bodies covered in light cream, pink, or red spots.
According to FishBase, there are currently 51 recognized species within this genus, of which 24 are native to Europe—although both numbers remain under scientific debate due to ongoing genetic and taxonomic research.
