Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 11; Wirbelzahl: 32 - 33. Hyphessobrycon wadai is distinguished from all congeners by the possession of the following characters: single humeral blotch present; no distinct caudal-peduncle blotch; no well-defined dark mid-lateral stripe on body, anal fin with 16-18 branched rays; dorsal fin with nine branched rays; and pelvic fin with six branched rays (Ref. 109743).

Inhabits clear water streams with moderate to rapid water currents, running over sand bottom. Feeds on filamentous algae, organic debris, unidentified insect larvae and fragments of adults of terrestrial insects and other unidentified arthropods (Ref. 109743).

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=0.01259 (0.00520 - 0.03049), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
