MEDITERRANEAN BARBEL, SOUTHERN BARBEL

Assessment Information

Red List Category & Criteria:

NT ver 3.1 (2001)

Year Assessed:

2006

Assessor/s:

Crivelli, A.J.

Evaluator/s:

Carmona, J. & Darwall, W. (Mediterranean Workshop, Dec. 2004)

Justification:

B. meridionalis has a large but fragmented distribution with an area of occupancy (AOO) of nearly 2,000 km² as it is present in only parts of streams and not the main rivers, it is also threatened by hybridisation with other Barbus species in addition it has undergone a population decline of nearly 30% (Crivelli, A. pers comm).

History:

1996

Lower Risk/least concern (Baillie and Groombridge 1996)

Geographic Range

Range Description:	It is restricted to the southern part of the Rhône river basin and to several coastal streams in France, and to few coastal streams in northern Catalonia, Spain.

Habitat and Ecology

Habitat and Ecology:

It is a small size barbel (<220 mm). It occurs in the upper and middle courses of mountainous rivers with clear, flowing and well oxygenated waters. Sensitive to pollution. Reproduction takes place between May and July. It can hybridize with Barbus barbus and Barbus haasi.

System:

Freshwater

List of Habitats:

5.1	Wetlands (inland) - Permanent Rivers/Streams/Creeks (includes waterfalls)
5.2	Wetlands (inland) - Seasonal/Intermittent/Irregular Rivers/Streams/Creeks
