Scientific Name: Eudontomyzon hellenicus
Species Authority: Vladykov, Renaud, Kott & Economidis, 1982

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Crivelli, A.J.
Reviewer(s): Barbieri, R. & Kottelat, M. (Mediterranean Workshop, Dec. 2004)
Justification:
This species is only known from two river basins with a total estimated extent of occurrence (EOO) <100 km² and area of occupancy (AOO) <10 km². Extensive survey has failed to find this species in one of these basins, the Louros, indicating a decline in the EOO and AOO. There is also a reported decline in quality of habitat due to water pollution, the number of locations, and number of mature individuals. It is also quite possible that the population within the Strymon river basin no longer exists — more survey work is recommended. On this basis the species is assessed as Critically Endangered.
History:
1996 Vulnerable
