Biology     Glossary (e.g. epibenthic)

A tropical, demersal species confined to freshwater environment unlike other congeners (Ref. 33568). Collected from below surface in channel with sandy-slime bottom (pH 8.0, conductivity 478 µÊS/cm, dissolved solids 242 mg/l, dissolved oxygen 6.9 mg/l, and 26°C) using a 90 cm seine net. Food fish (Ref. 93806).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00899 - 0.02218), b=3.09 (2.96 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
Price category (Ref. 80766):   Medium.
