Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7 - 9; Anal soft rays: 8 - 19. Body extremely compressed; lateral line strongly decurved; scaleless keel along belly from pelvic to anal fin; dorsal- fin origin behind pelvic-fin origin; mouth small, upturned on pointed snout; appears silver in clear and turbid water, and gold side and fins in coffee-colored water; fins red in southern hemisphere; dusky stripe along side, herringbone lines on upper side of young. Scales on lateral line 44-54; dorsal fin with 7-9 rays; anal fin with 8-19 rays, usually 11-14; rakers on 1st gill arch 17-19; and pharyngeal teeth 0,5-5,0 (Ref. 86798).

Inhabits vegetated lakes, ponds, swamps, backwaters and pools of creeks and small to medium rivers (Ref. 86798). Can tolerate low oxygen levels, high turbidity and high temperature; omnivorous but principally feed on plankton, insects and mollusks (Ref. 27549).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00681 - 0.01537), b=3.07 (2.95 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.1 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; tmax=5; Fec=200,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).

Price category (Ref. 80766): Unknown.
