Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 8; Afterflossenweichstrahlen: 7 - 8. Siphateles bicolor can be distinguished by the following characters: lateral line with 41-64 scales; dorsal fin usually with 8 rays; anal fin with 7-8 rays; pharyngeal teeth 0,5-5,0; deep, compressed body; dorsal-fin origin over pelvic- fin origin; fairly deep caudal peduncle; small, rounded fins; small, terminal to slightly subterminal mouth; does not extend to eye; dusky olive to dark green above; brassy brown side, often mottled in adult; silver white to yellow below; clear to dusky olive fins; young with dusky stripe along side; large individuals may have yellow to copper fins with pink, red, or orange bases, red-orange lower side (Ref. 86798).

Inhabits lakes and quiet, vegetated, mud or sand-bottomed pools of headwaters, creeks and small to large rivers (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00492 - 0.02938), b=3.03 (2.81 - 3.25), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.2 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.19-0.33).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
