Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Salmoniformes Salmonidae

Scientific Name: Salmo cettii Rafinesque, 1810
Taxonomic Notes: Often appears in the literature as S. macrostigma, a species endemic to Algeria. Trouts retaining parr marks in adults are also present in southwestern France (southern Garonne tributaries and Adour drainages, Atlantic basin; Aude drainage, Mediterranean basin) and Iberian Peninsula (Ebro basin, Mediterranean basin). They have also been called S. macrostigma but apparently represent several distinct, unnamed and unstudied species.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01

Reviewer(s): Bogutskaya, N., & Smith, K. (IUCN Freshwater Biodiversity Unit)
This species is found in Corsica, Sardinia, Sicily, and the Tyrrhenian basin of Italy from Magra drainage southward (streams in hilly areas; in lowland in karstic resurgences) where it is threatened by water abstraction, overfishing and stocking of non-native trouts (resulting in hybridisation and competition). It is suspected that in the past three generations (10 to 12 years) the population has declined by almost 30%, and it will continue to do so as water abstraction will most likely increase.
