Description synthétique
Clés d'identification | Morphologie | Morphométrie
Diagnosed from other cisco species in Europe by possessing the following characters: in life and shortly after death, head and body dark grey to black with violet iridescences; eye diameter 22-27% HL; lateral line straight; and gill rakers 41-46. Differs from sympatric Coregonus albula in Lake Onega by having all fins dark grey to black (vs. hyaline), eggs dark yellowish pink (vs. pale yellow); and usually attaining maturity at 20 cm SL (vs. 9-12 cm SL) (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Found in lakes at all depths. Preys on zooplankton and small benthos during juvenile stage and switches to fish diet at 17-20 cm SL. Life span ranges from 7-9 years, with exceptional records up to 19 years (Ref. 59043).
