Biologie     Verklarende woordenlijst (bv. epibenthic)

Inhabits rubble and gravel riffles of rivers and rocky lake shores. Individuals up to 5 cm feed on planktonic crustaceans and aquatic insect larvae especially that of midges and mayflies (Ref. 1998). Larger sculpins feed on minnows and other fishes (Ref. 1998). Possibly spawns in June (Ref. 1998).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.4   ±0.45 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Fec=448).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
