Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 14 - 17; Rückenflossenweichstrahlen (insgesamt) : 10 - 12; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 6 - 8. Diagnosis: high number of branchiospines on first outer branchial arch (23-31); first dorsal fin spine length 70-80% of the length of the 5th spine (Ref. 59155, 52307, 81260). When stressed with 2 continuous dark bands on body (Ref. 81260).

Found in middle sized or large rivers; small specimens prefer shallow regions and are found as single specimens or in small groups of 2-4 individuals between sunken wood or stones near the bank, while adults swim in deeper regions in the middle of the rivers (Ref. 59155). Diet consists mostly of detritus, aufwuchs and other, preferably vegetative, components (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±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).
