|Scientific Name:||Cottus petiti|
|Species Authority:||Bǎcescu & Bǎcescu-Meşter, 1964|
|Red List Category & Criteria:||Vulnerable D2 ver 3.1|
|Reviewer(s):||Freyhof, J. & Darwall, W. (Mediterranean Workshop, Dec. 2004)|
C. petiti occurs in one small restricted location (3 km stretch of the Lez River) with an area of occupancy (AOO) <20 km². Future introduction of C. gobio could cause the extinction of the species. Recent genetic work (Eppe et al. 1999) showed that this species is not different than any Cottus gobio populations. Consequently, its taxonomy might be wrong and further investigations on a large geographical scale is needed.
|Previously published Red List assessments:||
|Range Description:||It is restricted to a 3 km stretch of the Lez River (Le Lez) from the spring to the Lirou tributary in southern France north of the town of Montpellier.|
|Range Map:||Click here to open the map viewer and explore range.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||The Lez River is fed by a large resurgence draining a karstic plateau. Substrate is gravel and stony beds, temperature rarely exceed 20°C. Discharge is very regular.|
|Major Threat(s):||Water pollution, drying out of River Lez, and introduction of Cottus gobio are major threats. Water extraction for drinking water for the Montpellier town.|
|Conservation Actions:||It is listed in the Annex II of the European Union Habitats Directive.|
