Salvelinus is a group of fish often called char or charr. Some types are also known as "trout". These fish belong to the salmon family.
Char are found all around the northern parts of the world. Most of them are cold-water fish. They usually live in fresh water like lakes and rivers. However, many species also travel to the sea.
You can often spot char by their light-colored spots. These spots can be cream, pink, or red. They stand out against the fish's darker body. Char have small scales, and their fins often have white or cream edges.
Many types of char are popular for sport fishing. Some, like the lake trout (S. namaycush) and arctic char (S. alpinus), are also caught for food. Sometimes, fish raised for food escape and can become invasive species. This means they can harm the local environment.
Deepwater char are smaller types of char. They live in the deep parts of certain lakes, usually below 80 meters. These fish are very sensitive to changes in water quality. Sadly, one species, Salvelinus neocomensis, became extinct in the 1900s.

What's in a Name?
The exact origin of the name "char" is not fully known. It might come from an old Celtic language word. For example, the Irish word ceara means "fiery red." This could refer to the bright red belly of the Arctic char.
Another idea is that it came from a Middle Low German word, schar. This word meant "flounder" or "dab" (types of flatfish). It might also come from an older word meaning "to cut." This could describe the fish's shape.
Char Family Tree
Scientists group Salvelinus into three main subgroups, called subgenera. These are Baione, Cristovomer, and Salvelinus itself.
The Baione group includes the brook trout (S. fontinalis). It also included the silver trout (S. agassizii), which is now believed to be extinct. The Cristovomer group has only one member: the lake trout (S. namaycush). All other char species belong to the Salvelinus subgenus.
There's also a fish called the long-finned char (Salvethymus svetovidovi). Some scientists think it should be part of the Salvelinus group. If so, it would create a fourth subgroup called Salvethymus.
Many Kinds of Char
Just like with other salmon-like fish, it can be tricky to decide how many different species of Salvelinus there are. Scientists sometimes disagree! In 2015, a database called FishBase listed 54 species or subspecies. Many of these live in very specific local areas.
For example, the British Isles alone have 14 local species listed. However, many experts still consider them all to be types of the widespread Arctic char (S. alpinus).
The Arctic char (S. alpinus) is the most common and widespread Salvelinus species. It lives all around the Arctic regions. It is known as the most northern freshwater fish in the world.
In North America, there are five well-known species. Besides the Arctic char, these include the brook trout (S. fontinalis), bull trout (S. confluentus), Dolly Varden trout (S. malma), and lake trout (S. namaycush).

Hybrid Char
Sometimes, different types of char can breed together. This creates a mix of species called a hybrid. Here are some examples:
- S. alpinus × S. fontinalis – Alsatian char
- S. namaycush × S. fontinalis – splake, brookinaw
- S. fontinalis × Salmo trutta – tiger trout
