Carpiodes is a genus of suckers found in freshwater in North America,[1]containing species with exceptionally long lifespans for their body size.[2] Long neglected as 'rough fish' in traditional fisheries, in 2025 it was discovered that the three species of carpsucker can live more than 50 years.[2]
Characteristics
The fish in this genus have a long and hook-shaped dorsal fin. They have a silver body and a white to orange pelvic fin. They have a complete lateral line, and have a two-chambered gas chamber.[3] The three species of carpsucker are long-lived freshwater animals, with known maximum lifespans of 52 years (Quillback), and 56 years (Highfin carpsucker and River carpsucker).[2]
Species
There are currently three recognized species in the genus:[1]
- Carpiodes carpio(Rafinesque, 1820) (River carpsucker)
- Carpiodes cyprinus(Lesueur, 1817) (Quillback)
- Carpiodes velifer(Rafinesque, 1820) (Highfin carpsucker)
