Maturity: L_m 48.3, range 46 - 50.8 cm
Max length : 155 cm TL mannelijk / geslacht onbekend; (Ref. 86798); max. gepubliceerd gewicht: 55.8 kg (Ref. 40637); max. gerapporteerde leeftijd: 25 Jaren (Ref. 120825)

Adults inhabit pools with logs and other debris in low-gradient to moderate-gradient, small to large rivers. Also found in lakes and impoundments. Young occur in rocky and sandy runs and riffles (Ref. 5723, 86798). Juveniles feed on aquatic insect immature in riffle areas (Ref. 10294). Older individuals consume crayfish, clams and fishes (Ref. 93252).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00412 - 0.00733), b=3.13 (3.04 - 3.22), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.8 ±0.3 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.06-0.38; tm=3-6; tmax=34; Fec=6,900).

Fishing Vulnerability (Ref. 59153): High vulnerability (62 of 100).

Prijsklasse (Ref. 80766): Unknown.
