Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 8; Afterflossenweichstrahlen: 8. Has a prominent midlateral stripe on the body; two pairs of barbels, with the anterior (rostral) barbels extending at most to posterior margin of eye (Ref. 27732).

Occurs in rivers and swamps (Ref. 57235). Usually associated with standing or slow-flowing, shallow waters (Ref. 27732). Abundant in flooded rice-paddies, canals and ditches. Avoids large rivers and only moves from temporarily inundated habitats if necessitated by seasonal habitat disappearance . Moves into seasonally inundated areas as soon as they are flooded. Feeds on zooplankton, terrestrial insects and aquatic insect larvae. Occasionally sold fresh and used to make prahoc (Ref. 12693, 57235).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00173 - 0.01152), b=3.09 (2.86 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.45 se; based on food items.

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).

Preiskategorie (Ref. 80766): Unknown.
