Lacustrine, in open waters (Ref. 59043). Feeds on bottom invertebrates and on semi-pelagic crustaceans (Mysis relicta), and also on their own eggs (Ref. 6258).

Levenscyclus en paargedrag
Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Spawning takes place in the lakes, over beds of gravel or stones in relatively shallow waters. The eggs fall into spaces between the stones.

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00264 - 0.01091), b=3.22 (3.05 - 3.39), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.6 ±0.40 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
