Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2011

Very little information exists for this species. It is suspected that it hybridises with introduced trout species, but more information is needed to know the impacts of this. Illegal fishing is also a potential threat as the species is a large fish and most likely targeted. The taxonomy of the species also needs clarification before a full extinction risk assessment can be made.

For the European Union 27 region, this species is also assessed as Data Deficient (DD), with the same rationale as above.

Habitat and Ecology [top]

Habitat and Ecology:Habitat
The species occurs in lakes and large rivers. It spawns on gravel bottom.

A resident in lacustrine ecotypes, in the Lake Skadar basin the species overwinters in deep parts of lake, moving to main tributaries in summer.

Use and Trade [top]

Use and Trade: It is harvested for human consumption, and for sport fishing.

Threats [top]

Major Threat(s): Hybridisation with introduced trouts and illegal fishing are potential threats.

Conservation Actions [top]

Conservation Actions: No information available. More information is needed for this species, in particular on its threats, and it is in need of taxonomic clarification.
