Salvelinus grayi

Appearance
Compared to other members of the Salvelinus genus, it has a deeper body that is more laterally compressed, a shorter caudal peduncle and larger scales. It can be distinguished from other char by the whitish spots on upper flank and caudal and dorsal fins. Salvelinus grayi, also called Gray's char, Lough Melvin char or freshwater herring, is a lacustrine char in the family Salmonidae.
This species grows to an average length of 10 to 12 in (25 to 30 cm) and a weight of 8 ounces (230 g).
Range and habitat
It is only found in Lough Melvin, Ireland. Numbers of fish are declining and the species is considered critically endangered by the International Union for Conservation of Nature.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Salmonids need cold, oxygenated water and a clean gravel or open-lake feeding ground. Endemic whitefishes collapse when the lake is eutrophied or fished out.
In crisis
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.
