Maturity: L_m ? range ? - ? cm
Max length : 75.0 cm TL male/unsexed; (Ref. 5723); common length : 40.8 cm TL male/unsexed; (Ref. 12193); max. published weight: 4.0 kg (Ref. 40637); max. reported age: 9 years (Ref. 12193)

Inhabit rocky pools, runs and riffles in small to large rivers. Also occur in lakes (Ref. 5723, 10294). Adults feed on benthic insect larvae; juveniles consume microcrustacea and midge larvae (Ref. 10294).

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=0.00977 (0.00494 - 0.01932), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.41 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=9).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Price category (Ref. 80766): Unknown.
