Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ekologi
; air tawar bentopelagis. 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 / Size / Weight / umur
Maturity: Lm 27.0, range 25 - 30 cm
Max length : 35.0 cm TL jantan/; (Ref. 6258); common length : 30.0 cm TL jantan/; (Ref. 6258); Berat maksimum terpublikasi: 450.00 g (Ref. 6258); Umur maksimum dilaporkan: 10 Tahun (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.

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).
Trophic level (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.
Daya lenting (Ref.
120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (K=0.65; tm=3-4; tmax=10).
Fishing Vulnerability (Ref.
59153): Low vulnerability (23 of 100).
Nutrients (Ref.
