Biología     Glosario (por ej. epibenthic)

Recorded from coastal waters at sea. Lacustrine, at depths greater than 30 m, in Lake Ladoga commonly at 50-150 m (Ref. 59043). Specimens measuring 36-40 cm are more than 5 years old. Spawns for the first time at 4-6 years (Ref. 59043). Spawns from the end of November to 20 December (Ref. 593). Oviparous (Ref. 205). Eggs are buried in unguarded nests (Ref. 205). Feeds on benthic invertebrates, especially gammarids, molluscs and insect larvae (Ref. 59043).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00328 - 0.00878), b=3.22 (3.08 - 3.36), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.4   ±0.3 se; Based on size and trophs of closest relatives
Resiliencia (Ref. 69278):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (K=0.14-0.91; tm=3-5; tmax=19).
