Etymology: Salmo: Latin, salmo, Plinius = salmon (Ref. 45335); viridis: The specific name viridis is in reference to the diagnostic greenish coloration in some parts of body and fins of this species.

Short description Morphology | Morphometrics

Anal soft rays: 11 - 12; Vertebrae: 53 - 55. Salmo viridis can be distinguished from all its congeners from Morocco, except Salmo pallaryi, by the absence of spots or marks on the body. It differs from S. pallaryi by having lesser number of anal pterygophores (AP 10-11; Median=10) (vs. 12-14; Median=13) and shorter orbital length (horizontal orbital length with respect to the head length is 16-23% HL vs. 25-31% HL in Salmo pallaryi). It can be further diagnosed by the following combination of characters: vomer teeth in one row; premaxilla extended laterally, supramaxilla short and deep; dorsal fin pterygophores from 11 to 13 (Median=12); and one molecular autapomorphy in the MT-CYTB gene in the nucleotide position 508 (Ref. 107622).

Occurs in Isli Lake, a large, deep (?2 km of diameter, 92 m deep) and oligotrophic lake. Spawns in sandy beaches of the lake at the end of October and November (Ref. 107622).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00477 - 0.02296), b=3.03 (2.86 - 3.20), based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100) .
