Biology     Glossary (e.g. epibenthic)

Occurs throughout the principal riverbeds and sometimes in the flooded areas of forests. Its biology is similar to that of P. tigrinum but it appears to be more fond of shady streams. Feeds at night on fish (loricariids, cichlids and characoids) as well as crabs (Ref. 6868). Confines its foraging activities to riverbeds. Its yellowish flesh is succulent and like that of other silurids, it is without bones (Ref. 27188). Females reach a more notable size. They become sexually mature at 56 cm, males at 45 cm. Fecundity is estimated at 8 million eggs per kg (Ref. 35381). Utilized for human consumption.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.04 (2.86 - 3.22), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.78 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.31-0.47; tm=3-5; Tmax=8.7).
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
