Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Οικολογία
; Γλυκού νερού βενθοπελαγικό. 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 / Μέγεθος / Βάρος / Age
Maturity: Lm 27.0, range 25 - 30 cm
Max length : 35.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 6258); common length : 30.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 6258); μεγ. δημοσιευμένο βάρος: 450.00 g (Ref. 6258); μεγ. αναφερόμενη ηλικία: 10 έτη (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.
