Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Sinh thái học
; Nước ngọt Sống nổi và đáy. Temperate; 55°N - 52°N, 7°W - 6°W
Europe: Ireland: Lough Neagh, lower and upper Loughs Erne, Lough Ree and Lough Derg (Ref. 59043).
Length at first maturity / Bộ gần gũi / Khối lượng (Trọng lượng) / Age
Maturity: Lm 27.0, range 25 - 30 cm
Max length : 35.0 cm TL con đực/không giới tính; (Ref. 6258); common length : 30.0 cm TL con đực/không giới tính; (Ref. 6258); Khối lượng cực đại được công bố: 450.00 g (Ref. 6258); Tuổi cực đại được báo cáo: 10 các năm (Ref. 6258)
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).
Status of threat: Threatened by eutrophication, introductions and warming of lakes. Only remaining abundant population in Lough Neagh (Ref. 59043).
Spawning takes place in the lakes, over beds of gravel or stones in relatively shallow waters. The eggs fall into spaces between the stones.
