Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(i,ii,iii,iv) ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Crivelli, A.J.
Reviewer(s): Bianco, G, & Freyhof, J. (Mediterranean Workshop, Dec. 2004)
The species has an estimated area of occupancy (AOO) <500 km². It is restricted to three river basins, which are treated as three separate locations due to the major threat of introduced Chondrostoma genei. With a continuing decline in extent of occurrence (EOO) and AOO, habitat quality, and the number of subpopulations the species is assessed as Endangered.
Previously published Red List assessments:
1996 Lower Risk/near threatened (LR/nt)
1996 Lower Risk/near threatened (LR/nt)
