The Blue sucker, Cycleptus elongatus, is a freshwater species of fish in the sucker family. Huge migrations of these fast, powerful fish once migrated throughout the Mississippi River basin, and spring harvests of blue sucker were a staple food for early pioneers. Blue suckers are quite rare today, mainly due to the segmentation of habitat caused by the thousands of dams that have been built in the last century. Early records indicate that this fish once reached weights of over 40 lb, although 15-pounders are quite rare today.
Blue suckers eat aquatic insect larvae, crustaceans, plant materials and algae.
