Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 7; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 19 - 21.

Found in rivers only. Occurs at temperatures ranging from 26 to 32°C. Mainly diurnal. Feeds mainly on fine and coarse detritus, other plant material (particularly seeds and small pieces of bark), and especially prawns. Also preys on aquatic insects and nymphs, fishes, worms and leeches (Ref. 2847).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.41 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Preiskategorie (Ref. 80766): Medium.
