Biologie     Verklarende woordenlijst (bv. epibenthic)

Occurs in deep pools of large cold rivers and lakes (Ref. 5723). Most common in high mountainous areas where snowfields and glaciers are present (Ref. 5723). Rarely anadromous (Ref. 5723, Ref. 51243). Lacustrine form matures in lakes and spawns in tributaries, where young reside for one to three years (Ref. 10367).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00468 - 0.02039), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.7   ±0.57 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (62 of 100).
Prijsklasse (Ref. 80766):   Very high.
