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).
Assuming same mode of reproduction as in M. saxatilis.

50 = 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.

Generation time: 2.2 (1.9 - 4.6) years. Estimated as median ln(3)/K based on 13
growth studies.
