| Notas | Usually found in heavily vegetated swamps and ponds; occasionally in medium to large rivers and lakes with abundant vegetation (Ref. 5723). Migrations appear to be limited to inshore or upstream movements to spawning grounds in the spring and (presumably) reverse migrations to deeper water in the fall (Ref. 27547). Feeds on fish, zoobenthos and zooplankton (Ref. 27547). |
