Salmo peristericus, or the Prespa trout[2] is a variety of trout, a freshwater fish in the Salmonidae family. It is endemic to the Lake Prespa watershed at the border area of Greece and the Republic of Macedonia.[2][1]

Four populations are known: one in the Agios Germanos stream in north-western Greece, and the others in the Brajcinska and Kranska rivers and the Leva Reka stream of Macedonia.[2]

The Prespa trout is morphologically difficult to separate from other trouts of the region.[2] Genetic data show it is close to and derived from the Adriatic lineage of brown trout, and do not support a distinct species status.[3] Nevertheless, its protection as an Evolutionary Significant Unit is justified regardless of the taxonomic status.[2][3]
