Short description Morphology | Morphometrics

Dorsal soft rays (total): 13-15; Anal 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).

Africa: restricted to Algeria (Ref. 13696, 55619, 59043). The other peri-Mediterranean populations referred to as Salmo macrostigma belong to several species (Ref. 59043, 87713, 93146).

Biology     Glossary (e.g. epibenthic)

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

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=0.00955 (0.00644 - 0.01416), b=3.02 (2.90 - 3.14), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.61 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 2340).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
Price category (Ref. 80766):   Very high.
