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

Found in relatively deep (1-2 m) fast-flowing water, in areas with gravel or sand substrates. Juveniles (1-3cm TL) shoal together in schools of 30-100 individuals in very shallow water (5-25 cm), downstream. Adults occupy deeper water (1-2m), upstream. Usually occupies unshaded areas. Fast swimmers and not easily identified from water surface. Declining numbers due to intensive fishing by fish exporters.

Bayesian length-weight: a=0.01096 (0.00518 - 0.02319), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
