Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 3; Rückenflossenweichstrahlen (insgesamt) : 7 - 8; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 9 - 10; Wirbelzahl: 30. Can be diagnosed from all its congeners by the following characters: pre-dorsal scales 15-16; predorsal length 60.68% of SL; preanal length 65-71% of SL; eye diameter 27-38% of HL and 70-93% of inter-orbital width; and dorsal fin origin posterior to pelvic fin insertion (Ref. 75599).

Occurs in small hill stream with sandy bottom and numerous cobblestones. Food items found in the intestines include zooplankton and phytoplankton (Ref. 75599).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00210 - 0.01198), b=3.15 (2.93 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±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).
