More on author: Duméril.

Issue
A better resolved species level taxonomy and more detailed morphological examination of peri-Mediterranean and African 'macrostigma' trouts is needed and feasible.

Africa: restricted to Algeria (Ref. 13696, 55619, 59043, 87713), also in Mediterranean basins of Morocco (Ref. 107622). The other peri-Mediterranean populations referred to as Salmo macrostigma belong to several species (Ref. 87713).

Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i ryggfenan (totalt) : 13 - 15; Mjukstrålar i analfenan: 11 - 13; Ryggkotor: 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).

Biologi     Ordlista (t.ex. epibenthic)

Possesses a particular diet due to poor insular ichthyologic fauna; its food consists mainly of tadpoles, insects and urodela (Ref. 11941).
