The introduction of the use of molecular data has caused debates on the taxonomy of Corsican and Sardinian trouts, also referred to as Tyrrhenian trouts (i.e. Salmo trutta, Salmo macrostigma, Salmo cettii). A recent study by Delling et al. (2020) (Morphologic and genetic characterization of Corsican and Sardinian trout with comments on Salmo taxonomy. Knowl Manage Aquat Ecosyst 421: 21) introduces important evidence regarding the taxonomy of these populations. However, their subsequent denomination as Salmo sp., that is, an undefined taxon, could have serious consequences on their future conservation management plans. Considering their threatened status, the Tyrrhenian trouts should be referred to as Salmo trutta until the ongoing taxonomic uncertainty can be unambiguously resolved. These populations must then be treated as an Evolutionary Significant Unit (ESU) or as an Operational Conservation Unit (OCU) for further conservation managements plans, as already done for other Mediterranean trout lineages.
Résumé
La taxonomie des truites corses et sardes, également appelées truites tyrrhéniennes (i.e. Salmo trutta, Salmo macrostigma, Salmo cettii) a fait l'objet de débats depuis l'utilisation des premières données moléculaires. Une étude récente de Delling et al. (2020) (Morphologic and genetic characterization of Corsican and Sardinian trout with comments on Salmo taxonomy. Knowl Manage Aquat Ecosyst 421: 21) a présenté des éléments importants sur la taxonomie de ces populations. Cependant, leur dénomination comme Salmo sp. – i.e. espèce non déterminée − qui s'ensuivit, pourrait avoir de graves conséquences en terme de gestion future de la conservation de ces populations. Compte tenu de leur statut menacé, les truites tyrrhéniennes devraient être appelées Salmo trutta jusqu'à ce que l'incertitude taxonomique actuelle puisse être résolue sans ambiguïté. Ces populations doivent ensuite être traitées comme une Unité Évolutive Importante (ESU) ou comme une Unité Opérationnelle de Conservation (OCU) pour les futures gestions de conservation, comme c'est déjà le cas pour d'autres lignées de truites méditerranéennes.
