Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 21-28; Anale stekels 0; Anale zachte stralen: 27 - 35. body depth 2.9-3.7 x SL, anal base 3.2-4.7 x SL, caudal peduncle height 13.3-19.3 x SL. Eye diameter 2.7-4.6 x head length. Uniformly brilliant silver color, sometimes grayish or brownish.
Affinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.01137 - 0.01924), b=2.85 (2.80 - 2.90), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.0 se; based on diet studies.
Generation time: 2.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (K=0.53-1.10; tmax=2.5).
Fishing Vulnerability (Ref.
