Descrição breve
Chaves de identificação | Morfologia | Morfometria
Distinguished from all congeners in Italy by having the following unique characters: 7-11 large parr-marks in adults; and 15-20 large roundish, ocellated spots on flank, reddish or dark brown (ocellus about eye-size) (Ref. 59043).
Inhabits Lake Posta Fibreno, an elongated karstic lake with underwater springs and caves, 1.1km long, 0.1-0.3 km wide, 0.29 square kilometer, 285 m above sea level, 15 m deep (average depth 2.5 m), about 10°C throughout the year, and clear and well oxygenated water. Sometimes enters lake tributaries. Spawns close to underwater springs in December-January. The lake is very vulnerable to fish introduction or accidental pollution (Ref. 59043).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00488 - 0.02245), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
