Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 11 - 12; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 8. Anterior barbels very thick and dark, length less than 5.5 times in head length, less than 2 times in gape height, longer than eye diameter; oral gape inferior; dorsal head profile irregular, convex caudally and with a 'bump' caused by premaxillaries.

Over muddy, sandy and rocky substrates all over the lake, preferably in water deeper than 6 m. Feeds mainly on insect larvae, small mollusks, and detritus.

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=0.00427 (0.00195 - 0.00935), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.35 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
