Quillback

The quillback (Carpiodes cyprinus), also known as the quillback sucker or quillback carpsucker, is a type of freshwater fish of the sucker family widely distributed throughout North America. It is deeper-bodied than most suckers, leading to a fuller-bodied appearance. However, the quillback is not a carp. Quillback are catostomids, and like all catostomids, they do not have barbels around the mouth. The quillback is long-lived, with age up to 30 years found in Florida, and lifespans of 44 - 52 years in Canada, Minnesota, Colorado, and Wisconsin.

Distribution

The quillback is found throughout much of North America, from Saskatchewan to Florida, and from South Dakota to Alabama. The quillback occupies temperate, freshwater habitats. This includes many streams, lakes, channels and rivers. They prefer water that is clear, slow moving, highly productive and moderately deep. The quillback can commonly be found in the Hudson Bay, the Mississippi River basin, the Great Lakes, and drainages from the Delaware, Apalachicola, and Pearl rivers. They often comprise a large portion of the biomass of warmwater rivers, but they are very difficult to catch with traditional American angling methods. The quillback is closely related to the highfin carpsucker and the river carpsucker. All three species are rarely caught by anglers due to their feeding habits, but they have been caught occasionally on worms, minnows, and artificial lures.

Quillbacks usually feed in schools. They are omnivores and bottom feeders that prefer lakes, rivers and streams in which the water is clear at the bottom. The school of quillbacks moves slowly over a sand or gravel bottom when they eat. Their typical diet consists of aquatic insect larvae and other small organisms although they have also been known to eat molluscs and aquatic vegetation.
