Etymology: Salmo: Latin, salmo, Plinius = salmon (Ref. 45335); multipunctatus: The species name multipunctata [to be corrected in multipunctatus refers to its diagnostic pigmentation pattern, which is consttuted by numerous spots and marks along the body (Ref. 107622).

Short description
Morphology | Morphometrics
Vertebrae: 53 - 55. Diagnosis: It differs from other known species of the genus Salmo in the numerous irregular narrow parr marks, usually more than or equal to 14, in the lateral line; upper row of parr marks more than or equal to 10; lower row of parr marks variable, usually more than or equal to 5; two conspicuous black spots placed at the right and left sides of the iris and two less visible spots at the upper and lower sides of the iris; numerous black, small spots at the upper side of the body and several red ocellated and non-ocellated spots placed in the middle of the body; black spots sometimes extended to the opercular region and the caudal fin; ethmoid bone with a characteristic T shape; premaxilla bone with small and inclined upper process; from 14-16 scales from base of adipose fin to lateral line; from 12-14 dorsal fin pterygophores; and 9 molecular autopomorphies in MT-CYTB gene in the nucleotide positions 60, 216,474, 504, 732, 849, 915, 990, 1090 (Ref. 107622).
This species inhabits small and shallow streams with clear and cold waters (Ref. 107622). The habitat of this species suffers catastrophic seasonal floods that influence dramatically the demography of the population; the continuous deforestation of the Atlas Mountains and the disappearance of the riparian vegetation, increase the adverse effect of the overflows over the small Atlas rivers; overfishing is also a problem for a small population ; therefore this species should be included in the IUCN category of endangered (Ref. 107622).
