Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 1. Diagnosis: adipose fin always present; anterior nostrils closer to each other than posterior ones; snout reaching slightly beyond lower jaw; nasal barbel always reaching beyond orbit; eyes rather large (horizontal diameter 26,8-33,1% HL); inner side of pectoral spine feebly serrated (Ref. 43912).

Confined to larger lakes and rivers; possibly a shoaling species; polyphagous with a frugivorous tendency; stomach contents examined showed the presence of sand, mud, benthic vegetable remains, leaves, fruits and insect remains (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Probably of economic importance locally for fishermen of Lake Tumba; maximum reported TL 280mm (Ref. 43912).

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=0.00589 (0.00263 - 0.01321), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Assuming fec > 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Price category (Ref. 80766): Unknown.
