Scientific Name: Salvelinus inframundus
Species Authority: Regan, 1909
Synonym/s:
Salvelinus evasus Freyhof & Kottelat, 2005
Taxonomic Notes: Long known only from the original description, based on material from Orkney Islands. This or a similar species has recently been recorded from Loch Meallt. Above diagnosis largely based on latter population.

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1

Justification:
The species is regarded as extirpated from its type locality on the Orkney Islands (last recorded in 1908 when it was described), but there is no recent confirmation. A population of Salvelinus from Loch Mealt (photographed by Alexander and Adams in 2000) is tentatively identified as S. inframundus, but this needs confirmation. The impacts of the fish farming in Loch Mealt (Canadian Arctic Char) upon the native char population is unknown. More information is needed on the taxonomic identity of the char in Loch Mealt and the impact of the fish farming before a full Red List assessment can be made. The species could be Vulnerable to Extinct.
