Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Commonly found in lakes and rivers (Ref. 9258). Inhabits stony rivers (Ref. 9072). Migrates to the sea to breed. Oviparous (Ref. 205). Marketed fresh, smoked and frozen; eaten fried and broiled (Ref. 9988). Reports of reaching up to 2 meters and 50 kilograms are rare and more common historically; in recent times, only a few exceed 120 cm TL (Ref. 82796).

Estimates based on models

Preferred temperature (Ref. 115969): 10.6 - 18.3, mean 15.1 °C (based on 138 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00093 (0.00076 - 0.00115), b=3.20 (3.15 - 3.25), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.5 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179):  sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Tmax=60; tm=10-48 years based on age-length relationship.).
Verwundbarkeit (Ref. 59153):  Very high vulnerability (89 of 100) .
Preiskategorie (Ref. 80766):   Unknown.
