Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Inhabits lakes. This is the only species of Sardinella that is apparently found only, or even mainly, in freshwater. Presumably schooling. Also caught using ring nets (Ref. 5520). Mainly caught by gill net, beach seine, ring net and motorized push net (Refs.81494, 80728, 5520). Eaten fresh or dried (Ref. 5517). Is threatened by overfishing (Ref. 6308).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00395 - 0.01833), 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):  3.0   ±0.0 se; based on diet studies.
Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (17 of 100) .
Preiskategorie (Ref. 80766):   Medium.
