Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i ryggfenan (totalt) : 67 - 75; Mjukstrålar i analfenan: 61 - 70; Ryggkotor: 67 - 71. Possess the following unique combination of character states: body slender, body depth at anus 9.0-11.4% in SL; distance of occipital process to dorsal fin origin 9.9-11.8% in SL; dorsal and anal fins separate from caudal fin.

Facultative air-breathing (Ref. 126274); Found in freshwater sections of torrent streams, in clear, cool, fast flowing water over a substrate of sand, rocks and large granite boulders. Largely carnivorous, subsisting on small fish, crustaceans and insects. Seems to be nocturnal, emerging into the open at night. Also Ref. 84801.

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=0.00794 (0.00357 - 0.01766), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).
