Taxonomy [top]

Kingdom	Phylum	Class	Order	Family
ANIMALIA	CHORDATA	ACTINOPTERYGII	SALMONIFORMES	SALMONIDAE

Scientific Name:

Salmo stomachicus

Species Authority:

Günther, 1866

Common Name/s:

English

–

Gillaroo

Taxonomic Notes:

Similar trouts have been recorded from Loughs Neagh, Conn and Corib (Ireland) and from Lochs Fadagoa, Mulach-Corrie and Assynt (Scotland). There are no data that allow a conclusion on whether they are conspecific with the Melvin ones. The above diagnosis is based on the Melvin population only.

Assessment Information [top]

Red List Category & Criteria:	Vulnerable D2 ver 3.1
Year Published:	2008
Assessor/s:	Freyhof, J. & Kottelat, M.
Reviewer/s:	Bogutskaya, N., & Smith, K. (IUCN Freshwater Biodiversity Unit)
Justification: The species is endemic to Lough Melvin (21 km²), Ireland. There is a potential threat to the species from eutrophication and introduced species. Eutrophication has caused the extinction of fish species from other Irish lakes. S. stomachicus may be more widespread in other lakes of Ireland and Scotland - if this is proved to be true the species could be Least Concern

Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Lacustrine, in shallow benthic waters. Spawns near or in lake outlet. May also spawn on sandy bays in middle region of northern shore. Biology: Spawns in November-December. Juveniles swim upstream to return to lake. Feeds primarily on snails and trichopteran larvae, supplemented by other benthic invertebrates.
Systems:	Freshwater

Threats [top]

Major Threat(s):	Eutrophication and introduced species are potential threats to the species.
