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.

Habitat and Ecology [top]

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.

Threats [top]

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 [top]

Conservation Actions: It is listed in the Annex II of the European Union Habitats Directive.
