📖 Overview

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 . The spawning of this species takes place at the end of October and November in the sandy beaches of the lake . 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 .

🐟 Physical Description

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 . 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 . : fusiform / normal.
