Comments: Known from the middle Madeira and Mamoré rivers. Habitats of this species have been severely altered by the construction of hydroelectric power plants, destroying the former Santo Antônio and Jirau rapids and transforming more than 200 km of the rio Madeira, enlarging the riverbed and reducing the current (Ref. 104707). Status of threat: should be classifiedas Least Concern (LC) (Ref. 104707).

Caught mostly in cofferdams at the construction sites of the hydroelectric power plants of Santo Antônio and Jirau (former Santo Antônio and Jirau rapids) in rio Madeira. Most specimens were collected at depths of 3.1-11 m and 4.1 to 8.5 m using trawl nets, indicating preference for deep-water habitats with strong current (Ref. 104707).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00450 - 0.02327), b=3.04 (2.84 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
