Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 20 - 22; Rayons mous dorsaux (Total) : 10 - 12; Épines anales: 3; Rayons mous anaux: 7 - 9. Distinguished by the following characters: 6 to 8 irregular blotches along the upper lateral line; lacking scattered dark spots on flanks; low number (47-55) of E1 scales; and a slightly prognathous lower jaw. Females possess a distinctive coloration of the dorsal fin, with a wide black longitudinal stripe on the distal portion with an equally wide red stripe below it (Ref. 85167).

Recorded both before and after the Urugua-í hydroelectrical dam was built in 1989. Presently inhabits also directly in the reservoir. Occurs in a moderately fast flowing river with tributaries of an average depth of 1 m outside of the dam influence and with bottom consisting of mud, sand with gravel and/or bedrock. Sympatric with Crenicichla yaha(Ref. 85167).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00338 - 0.01626), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
