Biology     Glossary (e.g. epibenthic)

Inhabits streams and rivers without strong currents (Ref. 26543) and lentic areas (Ref. 1129). Vivacious, eats small fish and will bite pieces of meat (Ref. 5518). Sometimes used as table fish; flesh of good flavor but with lots of fish bones.

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=0.01318 (0.01108 - 0.01568), b=3.07 (3.03 - 3.11), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.3 se; based on diet studies.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
Price category (Ref. 80766):   Unknown.
