Biology     Glossary (e.g. epibenthic)

Inhabits main channels, pools, backwaters of small to large rivers, lakes, and impoundments (Ref. 86798). Feeds on cladocera and cyclopoid copepods supplemented with midge larvae (Ref. 10294). Oviparous (Ref. 205). Prefers water with depth of less than 5 m (Ref. 121623).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 205). Breed in streams and ponds with rapid flow, on sand and gravel, or in weedy places (Ref. 205). One female may mate with several males (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00823 - 0.01529), b=3.03 (2.94 - 3.12), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.41 se; based on food items.
Generation time: 13.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=20).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (70 of 100).
Price category (Ref. 80766):   Unknown.
