Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 15 - 16; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 12 - 13; गुदा कांटा: 3; ऐनल सौफट रेज़: 9 - 10. Diagnosis: lower pharyngeal bone about as long as broad, with anterior lamella shorter than toothed area; median pharyngeal teeth not broadened; upper part of caudal fin yellow-orange, lower part greyish; dorsal fin with 15-16 spines and 12-14 soft rays; 9-13 lower gill-rakers (Ref. 53405).

Mainly herbivorous, but also takes small amounts of insects; pair-bonding, biparental, open substrate spawner that builds large, deep pits on the river bottom (Ref. 52307).

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=0.01862 (0.00830 - 0.04177), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
