Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce benthopélagique. 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 / Taille / Poids / Âge
Maturity: Lm 27.0, range 25 - 30 cm
Max length : 35.0 cm TL mâle / non sexé; (Ref. 6258); common length : 30.0 cm TL mâle / non sexé; (Ref. 6258); poids max. publié: 450.00 g (Ref. 6258); âge max. reporté: 10 années (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).
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Spawning takes place in the lakes, over beds of gravel or stones in relatively shallow waters. The eggs fall into spaces between the stones.

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 (0.00264 - 0.01091), b=3.22 (3.05 - 3.39), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.6 ±0.40 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.65; tm=3-4; tmax=10).
Fishing Vulnerability (Ref.
59153): Low vulnerability (23 of 100).
Nutrients (Ref.
124155): Calcium = 21.7 [10.1, 46.6] mg/100g; Iron = 0.481 [0.288, 0.759] mg/100g; Protein = 18.1 [16.8, 19.3] %; Omega3 = 2.31 [0.76, 8.33] g/100g; Selenium = 24 [9, 61] μg/100g; VitaminA = 29.3 [9.2, 89.6] μg/100g; Zinc = 0.658 [0.491, 0.881] mg/100g (wet weight);
