Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 6-9; Afterflossenstacheln 0; Afterflossenweichstrahlen: 8 - 10. Long narrow snout. Olivaceous brown above and white below. Dark spots on median fins and on body (Ref. 37032).

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

Facultative air-breathing (Ref. 126274); Adults occur in sluggish pools, backwaters and oxbows of medium to large rivers, and lakes (Ref. 10294). Usually found near vegetation. Occasionally found in brackish waters. Spawning occur in freshwater and possibly slightly brackish water (Ref. 4639). Migrate up rivers during the spawning season (Ref. 4639). Eggs and larvae are demersal and adhesive (Ref. 4639). Voracious predator, feeding on various fishes and crustaceans. The roe is poisonous.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5781   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00121 - 0.00751), b=3.18 (2.96 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.73 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tm=3-6; tmax=36; Fec=1,110).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100).
