| Notas | Live in vegetated lakes, swamps, and backwaters and quiet pools of creeks and small to medium rivers (Ref. 26373, 10294). Also found in deep, cold water with little or no vegetation (Ref. 39109, 39108). Adults migrate to deeper water during winter (Ref. 39110, 39097, 39111) undertaking shoreward spawning migrations soon after spring ice disappears (Ref. 39109). Juveniles tend to lie motionless near shore or burrow themselves in mud beneath debris (Ref. 39112). Larvae hide among vegetation (Ref. 39113). Young feed on insects and crustacea (Ref. 10294). |
