Actinopteri (ray-finned fishes) > Salmoniformes
(Salmons) > Salmonidae
(Salmonids) > Coregoninae
Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; anadromous; depth range 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 / Weight / Age
Maturity: Lm 29.2, range 19 - 46 cm
Max length : 55.0 cm SL male/unsexed; (Ref. 59043); max. published weight: 2.0 kg (Ref. 593); max. reported age: 20 years (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).
