Length at first maturity / Size / Weight / Age

Maturity: L_m 28.0 range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 86798); 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)

Inhabits lakes, ponds and pools of small to large rivers (Ref. 5723, 86798). Occurs at depths <14 m (Ref. 120827). Juveniles feed on small invertebrates such as cladocerans, copepods, and midge larvae. Adults are piscivorous, consuming shad, silversides, and occasional young sunfish (Ref. 10294). Spawns near the surface (Ref. 120818).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00641 - 0.02055), b=3.07 (2.91 - 3.23), in cm Total Length, 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. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23-0.73; tmax=9).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
