Blue suckers are very rare today, thought to be due to the segmentation of habitat caused by the thousands of dams which have been built in the last century.

Blues frequent the thalweg of large river systems, in heavy current.

Blue suckers obtain their food off the bottom of rivers and other bodies of freshwater through a mouth in the inferior position.

Some organisms that they eat are aquatic insect larvae, crustaceans, plant materials and algae.

Fifty-three degrees is the average water temperature in which males and females find their spawning area.

The peak water temperature is sixty-two degrees and the actual spawning time will usually last around two weeks.

[7] Recent evidence indicates their recruitment patterns are episodic, and their life history is longer-lived than previously realized.
