Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 7; गुदा कांटा: 3; ऐनल सौफट रेज़: 5; जानवरों की रीड़ का जोड़: 41 - 43. Head conical, wide, slightly flattened. Barbel long, reaching beyond posterior edge of eye, caudal peduncle low, epithelial crests on dorsal scales absent; supraorbital seismosensory canal not connected with infraorbital one (Ref. 28796); and anal fin with 5½ branched rays (Ref. 59043).

Inhabits high-gradient stretches of large rivers with fast (not turbulent) current and gravel or sand bottom. Nocturnal, found near shores at night on mud or sand bottom. Appears to spawn early and have a short spawning period. Only large juveniles were encountered in July (Ref. 59043).

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=0.00603 (0.00294 - 0.01235), b=3.12 (2.95 - 3.29), 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

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Preliminary K or Fecundity.).
