Scientific Name: Salmo marmoratus
Species Authority: Cuvier, 1829

Assessment Information [top]

Red List Category & Criteria: Least Concern     ver 3.1
Year Assessed: 2006
Assessor/s: Crivelli, A.J.
Reviewer/s: Freyhof, J. & Darwall, W. (Mediterranean Workshop, Dec. 2004)
Justification:
In Slovenia there is estimated to be around 10,000 individuals of the pure species at seven locations with a combined area of occupancy (AOO) of <20 km². The subpopulations in Italy need more research, as more subpopulations are likely to be found in addition to the three already identified. The stocking of foreign trout continues and may reduce population numbers of genetically pure marble trout. However, the populations in Slovenia, and to a lesser extent in Italy, are safe and have no major widespread threats (Crivelli, A. pers comm).
History:
1996 – Data Deficient (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description: It is restricted to southern Switzerland, northern Italy and Adriatic basin of Slovenia. It has been introduced in several countries in Europe. There are seven pure subpopulations in Slovenia and three known pure subpopulations in Italy (more research needed as there may be more).
