Biologia     Glossário (ex. 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 based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00325 - 0.00886), b=3.22 (3.08 - 3.36), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.4   ±0.3 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.14-0.91; tm=3-5; tmax=19).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100).
