Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 11; Radios blandos anales: 8. Schizothorax beipanensis is distinguished from all congeners by the combination of the following characters: absence of horny sheath on the lower jaw; upper lip developed; lower lip developed, trilobed; postlabial groove continuous, with a minute median lobe. Schizothorax beipanensis can be distinguished from S. griseus by the absence (vs. presence) of black spots on the flank, along the lateral line; distal 20-25 % of the last unbranched dorsal-fin ray soft (vs. strong); rostral barbel not reaching (vs. reaching) the middle of the eye; eye diameter 58.5-120.1 % length of maxillary barbel (vs. 33.4-93.7 %). Schizothorax beipanensis is most similar to S.heterophysallidos, from which it is distinguished, however, by the unique air bladder of the latter (Ref. 80483).

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=0.00851 (0.00408 - 0.01776), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.5 ±0.1 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
