; пресноводный демерсальный; анадромный; пределы глубины 30 - 150 m (Ref. 59043). Temperate
Europe: Baltic: Bothnian Gulf, Gotland (missing along Swedish coast southward of Stockholm); southern Baltic: from Germany to Gulf of Finland; several landlocked populations in Sweden (Lakes Vänern, Vättern, Locknesjön, Storvindeln, Storlaisan, Skalka-Parkijaur, Arjeplog) and Russia (Neva drainage, Lakes Ladoga and Onega).
Length at first maturity / Size / Вес / Возраст
Maturity: Lm 29.2, range 19 - 46 cm
Max length : 55.0 cm SL самец/пол неопределен; (Ref. 59043); наибольший вес (опубликованные данные): 2.0 kg (Ref. 593); наибольший возраст (опубликованны данные): 20 годы (Ref. 59043)
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).
Distinct pairing (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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).
Trophic level (Ref.
69278): 3.4 ±0.3 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (K=0.14-0.91; tm=3-5; tmax=19).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (47 of 100).
