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; benthopelagic. 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). Appendix III of the Bern Convention (protected fauna) (Ref. 1489).
Length at first maturity / Size / Weight / Age
Maturity: Lm 27.0, range 25 - 30 cm
Max length : 35.0 cm TL male/unsexed; (Ref. 6258); common length : 30.0 cm TL male/unsexed; (Ref. 6258); max. published weight: 450.00 g (Ref. 6258); max. reported age: 10 years (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
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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. 82805
= 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.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.65; tm=3-4; tmax=10).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
