Etymology: Salmo: Latin, salmo, Plinius = salmon (Ref. 45335); viridis: The species name viridis refers to its diagnostic greenish colouration in some parts of body and fins (Ref. 107622)

Morphology | Morphometrics
Vertebrae: 53 - 55. Diagnosis: It differs from other known species of the genus Salmo from Morocco, except Salmo pallaryi, by the absence of spots or marks on the body; it has a lesser number of anal pterygophores, 10-11 than Salmo pallaryi, 12-14, and shorter orbital length; horizontal orbital length with respect to the head length is 16-23% of head length in Salmo viridis vs. 25-31% of head length in Salmo pallaryi (Ref. 107622). The following combination of characters are also diagnostic to Salmo viridis: vomer teeth in one row, premaxilla extended laterally, supramaxilla short and deep, dorsal fin pterygophores from 11 to 13; and one molecular autapomorphy in the MT-CYTB gene in the nucleotide position 508 (Ref. 107622).
This species inhabits Isli Lake, situated on a high plateau, 2270 meters above sea level; it is a large and deep, ±2 km of diameter and 92 m deep, oligotrophic lake (Ref. 107622). The spawning of this species takes place at the end of October and November in the sandy beaches of the lake (Ref. 107622). The habitat of this species is threatened due to eutrophication, related to intensive overpasture; overfishing is also a problem due to the low protection of the lake; no juveniles have been observed in the last years and several malformations in fins and skull were observed; therefore this species should be included in the IUCN category of endangered (Ref. 107622).
