Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Wirbelzahl: 33 - 34. Diagnosis: Zaireichthys heterurus is distinguished from all other species of Zaireichthys by the presence of only 5 principal rays in the lower lobe of the caudal fin (Ref. 86935). The species has, like Zaireichthys zonatus a broad dark collar immediately posterior to head; larger specimens become stouter, more than any other leptoglanin species (Ref. 86935).

Found in clear, swift flowing tributaries lying to the east of the Congo River mainstream (Ref. 51287).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 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).
