Ferox trout (Salmo ferox) is a variety of trout found in oligotrophic lakes of Ireland, England, Scotland and Wales. 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] However, it is uncertain whether the ferox of different lakes are all of a single origin.[1] This fish grows to a length of 80 centimetres (31 in) SL.[2]
Scottish authorities currently do not regard Scottish ferox to be taxonomically distinct from Salmo trutta.[3]

Inhabits large oligotrophic lakes. In Scotland, this species occurs usually in lakes inhabited by Salvelinus species on which it preys. Feeds on fishes and a variety of insects. In Scotland, preys on invertebrates until about 30 cm SL, then becomes piscivorous, feeding mostly on Salvelinus species. Spawns only in the larger and deeper tributaries (Ref. 59043).

Distinguished from its congeners in British Isles by its unique body depth about 4.6-5.0 times in SL. Differs further by the combination of the following characters: body brown to silvery, black spots small (equal to or smaller than pupil), few or absent; large size; and maxilla reaching beyond posterior margin of eye (Ref. 59043).
