The main predators of Arctic char include sea otters (Enhyrda lutris), polar bears (Ursus maritimus), humans (Homo sapiens), ferox trout (Salmo ferox), and other fish species. [36] [37] Dwarf Arctic char are also often cannibalistically consumed by giant Arctic char. [36] [37] As ferox trout are an apex predator, Arctic char is thus a key ...
The Sunapee Lake strain of the Sunapee trout was discovered in 1977 when Kent Ball, of Idaho Fish and Game, discovered a char species living with brook trout in a mountain lake in Idaho. Analysis by Robert Benhke , Eric Wagner, and Steve Culver proved the species to be a presumably introduced population of Sunapee trout.

Kirikuchi char remain in two separate headwater streams of the Totsu River system, and they retain little genetic variation. [2] The Kirikuchi Char is endangered due to human disturbances, including degradation and overharvesting. Additionally, the species continues to become more endangered due to the loss of genetic diversity from ...

[17] [16] The specific epithet "fontinalis" comes from the Latin for "of a spring or fountain", in reference to the clear, cold streams and ponds in its native habitat. [18] [3]
Ferox trout is a traditional name for large, piscivorous trout, which in Scotland feed largely on Arctic char. It has been argued to be a distinct species, being reproductively isolated from "normal" brown trout ( Salmo trutta ) of the same lakes, particularly in Ireland. [ 1 ]
