Max length : 45.0 cm TL male/unsexed; (Ref. 5723); common length : 31.8 cm TL male/unsexed; (Ref. 12193); max. published weight: 3.1 kg (Ref. 4699); max. reported age: 9 years (Ref. 12193)

Biology     Glossary (e.g. epibenthic)

Occur in lakes, ponds and pools of small to large rivers (Ref. 5723, 10294). Juveniles feed on small invertebrates such as cladocerans, copepods, and midge larvae. Adults are piscivorous, consuming shad, silversides, and occasional young sunfish (Ref. 10294).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5781   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00604 - 0.01989), b=3.08 (2.91 - 3.25), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.68 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23-0.73; tmax=9).
Prior r = 0.67, 2 SD range = 0.44 - 1.04, log(r) = -0.4, SD log(r) = 0.22, Based on: 1 M, 11 K, 2 tgen, 1 tmax, 1 Fec records
Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100) .
