Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 12; Afterflossenweichstrahlen: 31 - 35; Wirbelzahl: 36 - 37.

Found in rivers and creeks in lentic habitats over detritus and decomposing vegetal material with low transparency, neutral pH, high dissolved oxygen, high conductivity and total solids, and low turbidity and hardness. These water parameters indicate a highly disturbed environment that affects the survival of this species and those that share its habitat (Ref. 104976).

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=0.01413 (0.00599 - 0.03330), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±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).
