Maturity: L_m ? range ? - ? cm
Max length : 18.0 cm TL Männchen/unbestimmt; (Ref. 5723); common length : 12.5 cm TL Männchen/unbestimmt; (Ref. 12193); max. veröff. Alter: 3.00 Jahre (Ref. 12193)

Most common over gravel and sand in medium-sized rivers but can be found almost anywhere from small, fast-flowing rock-bottomed streams to vegetated lakes (Ref. 5723, 10294). Adults feed on larvae of midges, mayflies, caddisflies (especially hydropsychids), riffle beetles, stoneflies, limpets, and fish eggs (Ref. 10294). Eggs are found buried in the substrate (Ref. 7043).

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=0.00631 (0.00359 - 0.01109), b=3.16 (3.00 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.46 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tmax=3; Fec=97-611).

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