Taxonomy

Name

The English word "char[r]" is thought to derive from Old Irish ceara/cera meaning "[blood] red,"[9] referring to its pink-red underside.[10][11] This would also connect with its Welsh name torgoch, "red belly."[12]

Scientific name

The describer, Albert Günther, named the fish after his longtime colleague John Edward Gray.

Biology

Salvelinus grayi is benthopelagic, living at 10–30 m (30–100 ft), except during spawning season. It feeds on water fleas (crustacean of the order Cladocera). It spawns in November, in shallow rocky areas. Its maximum length is 25 cm (10 inches). It can be distinguished from other char by the whitish spots on upper flank and caudal and dorsal fins.[13]

Conservation

Recorded numbers in Lough Melvin declined from 33 in 1975 and 42 in 1986 to only 12 in 2001, and the species is considered critically endangered. Common rudd introduction and eutrophication are blamed for the decline.[1]
