Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 7; गुदा कांटा: 0; ऐनल सौफट रेज़: 19 - 21.

Found in rivers only. Occurs at temperatures ranging from 26 to 32°C. Mainly diurnal. Feeds mainly on fine and coarse detritus, other plant material (particularly seeds and small pieces of bark), and especially prawns. Also preys on aquatic insects and nymphs, fishes, worms and leeches (Ref. 2847).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.41 se; based on food items.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Price category (Ref. 80766): Medium.
