Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 0; Raggi anali molli: 8. Body depth 1 to 1.1 times in head length; ventral fin length less than 1.7 times in head length; nuchal hump starts gradually at occiput; silvery white.

Occurs especially over muddy and sandy substrates all over the lake, preferably in water deeper than 6 m. A benthivore that at a larger size turns into a piscivore. Specimens smaller than 15 cm FL mainly eat insect larvae. Mollusks and plant material become more important with increased size. When fish reach sizes of 25 cm FL or more, fish are their main food.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00430 - 0.02123), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.50 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).
