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=0.01450 (0.00803 - 0.02619), b=3.13 (2.96 - 3.30), based on LWR estimates for species & Subfamily-body shape (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).
Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100) .
Price category (Ref. 80766):   Unknown.
