This species is distinguished from its congeners entering the freshwater in Atlantic basin by having 43-53 thin gill rakers at about 15-20 cm SL (Ref. 59043).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults are pelagic in lacustrine areas (Ref. 59043). The females are larger than males. They spawn in June to July on gravel bars and gravelled shallows around large islands of the lake. Feed mainly on zooplankton. Population occupies a very small range and is threatened by eutrophication (Ref. 59043).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00370 - 0.01703), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.6   ±0.4 se; based on size and trophs of closest relatives
Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
