Size / Gewicht / Alter

Maturity: L_m ? range ? - ? cm
Max length : 7.1 cm TL Männchen/unbestimmt; (Ref. 5723); common length : 5.0 cm TL Männchen/unbestimmt; (Ref. 12193); max. veröff. Alter: 3.00 Jahre (Ref. 12193)

Inhabits sluggish riffles over rocks or debris in small to large rivers; also lowland lakes (Ref. 5723), creeks, swamps and reservoirs (Ref. 10294). Feeds mainly on midge and blackfly larvae (Diptera); small fish consumes more microcrustaceans (Ref. 79012).

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=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (tmax=3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
