Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 16; Spine anali 0; Raggi anali molli: 12 - 13; Vertebre: 56 - 58. Diagnosis: Salmo akairos differs from all other Salmo species and archaic trouts by the combination of contrasting black and white leading edges on dorsal and anal fins and the lack of dark spots on the sides of the body; high number of dorsal fin pterygiophores, 14-16 is distinctive, as other Salmo species and archaic trouts have modally 12-13; high number of gill rakers, 19-23, is also diagnostic with slight overlap in comparison with S. trutta often having a colour pattern on the fins similar to that of S. akairos (Ref. 55619).

Analysis of stomach content revealed Cyclops, terrestrial arthropods and a dense mat of filamentous algae and diatoms (Ref. 55619). Spawning period is in late autumn (Ref. 55619).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00488 - 0.02245), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.30 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Price category (Ref. 80766): Very high.
