Taxonomy [top]

Kingdom	Phylum	Class	Order	Family
ANIMALIA	CHORDATA	ACTINOPTERYGII	SALMONIFORMES	SALMONIDAE

Scientific Name:

Salmo ferox

Species Authority:

Jardine, 1835

Common Name/s:

English

–

Ferox Trout

Taxonomic Notes:

Several populations of large, piscivorous trouts from Ireland, northern Scotland, Cumbria and Wales are called ferox trouts. They are recognized as a distinct species on the basis of their existence in sympatry with genetically distinct S. trutta in several lakes, but it remains to be demonstrated whether all ferox trouts are conspecific. Some of these individuals or populations might be old, large, piscivorous, lacustrine S. trutta.

Justification: Several populations of large, piscivorous trouts from Ireland, northern Scotland, Cumbria and Wales are called ferox trouts. They are recognized as a distinct species on the basis of their existence in sympatry with genetically distinct S. trutta in several lakes, but it remains to be demonstrated whether all ferox trouts are conspecific. Some of these individuals or populations might be old, large, piscivorous, lacustrine S. trutta. More information is needed on the distribution, status and population and threats of S. ferox in these lakes.

Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Large oligotrophic lakes; in Scotland usually only in lakes inhabited by Salvelinus species on which it preys. Spawns only in the larger and deeper tributaries. Biology: Lives up to 23 years. Spawns in November-December. Feeds on fishes and a variety of insects. In Scotland, feeds on invertebrates until about 300 mm SL, then switches to a fish diet, mostly Salvelinus species.
Systems:	Freshwater
