Short description Morfologia | Morfometria

Distinguished by having the following characters: body long and slender; snout long and pointed; caudal fin base with 2 black spots partially fused into short bar; straw colored to olive above, 6-9 brown saddles; 7-9 large green Us alternate with orange bars (faint on female) along side; yellow below. Breeding males with bright orange bars on side, red-orange edge on 1st dorsal fin, bands of red -orange spots on 2nd dorsal and caudal fins, blue-green anal and pelvic fins. Lateral line usually incomplete, with 55-69 lateral scales, usually 63 or more; and 49-66 pored lateral-line scales, usually more than 52 (Ref. 86798).

Inhabits rocky riffles and pools of headwaters, creeks and small rivers (Ref. 5723, 10294). Feeds on mayfly nymphs (heptageniids, baetids), blackfly and midge larvae, and lesser numbers of caddisfly, stonefly, and beetle larvae (Ref. 10294).

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=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=0.67-0.79).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
