Etymology: Salmo: Latin, salmo, Plinius = salmon (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; benthopelagic; anadromous (Ref. 51243). Subtropical
Africa: Algeria (Ref. 13696, 55619, 59043); Morocco (Ref. 107622). However, other peri-Mediterranean populations referred to as Salmo macrostigma are believed to belong to several species (Ref. 59043, 87713, 93146).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 18 - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 3562)
Morphology | Morphometrics
soft rays: 11 - 13;
Vertebrae: 57 - 58. Diagnosis: dorsal fin slightly higher than long; located more posteriorly than in other Salmo species; caudal fin more forked than other Salmo species; 8-12 round, black spots (parr marks) on sides (Ref. 4904, 52923, 94703, 94704), which are more prominent in juveniles and are retained in adults (Ref. 55619). Low gill raker count and dark spots on sides distinguish it from S. akairos; it differs from S. trutta in slightly lower vertebral count and pyloric caeca counts, and having the parr marks more conspicuous; 10-11 anal fin pterygiophores (Ref. 55619). 14-17 small scales between adipose fin and lateral line (Ref. 1878, 52923, 55619).
Possesses a particular diet due to poor insular ichthyologic fauna; its food consists mainly of tadpoles, insects and urodela (Ref. 11941).
