Biology     Glossary (e.g. epibenthic)

Habitat is highly variable which includes rivers, creeks, swamps, marshy lagoons, lakes and reservoirs (Ref. 44894). Often forms aggregations at or near the surface of rocky pools or congregates along stream margins where there is vegetative cover or submerged logs and branches (Ref. 44894).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
