Краткое описание
определительные ключи | морфология | морфометрия
Distinguished from its congeners in British Isles by its unique dark brown or black fins, especially pectorals. Differs further by the combination of the following characters: body light brown to silvery with many large spots; red spots absent or few, small, inconspicuous, restricted to posterior part of body; and body depth about 3.9-4.4 times in SL (Ref. 59043).
A lacustrine and pelagic species, occurring in relatively deep water. Feeds predominantly on mid-water plankton, especially Cladocera, and chironomid pupae. Migrates to tributaries for spawning. Spawns in most lake tributaries. Attains a maximum size of up to about 33 cm SL (Ref. 59043).

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=0.01047 (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).
Trophic level (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
