SCIENTIFIC NAME: Carpiodes velifer
Characteristics:The highfin carpsucker is named for its elongate anterior dorsal fin rays, which when depressed are almost as long as the dorsal fin base. The dorsal fin has 22 to 27 rays; the anal fin has seven or eight rays. The lateral line contains 36 to 38 scales. The snout is blunt and rounded. The upper jaw reaches the front edge of the eye, and a small, nipple-shaped projection appears on the front edge of the lower lip. Highfin carpsuckers have silvery to light bronze bodies and clear fins.
ADULT SIZE: 10 to 16 in (254 to 406 mm)
DISTRIBUTION: The highfin carpsucker is a rare catch in Florida where their range on the Gulf Coast is from Louisiana eastward to the Choctawhatchee River of Florida. This schooling fish found in moderately flowing clean waters can reach 20 inches and weigh three pounds. This schooling species occurs primarily in rivers and reservoirs and occasionally in moderate or large streams. Highfins are widespread and often abundant in the Mobile basin, particularly below the Fall Line and in the tailwaters of most locks and dams. Royal D. Suttkus (1995, personal communication) believes that a new species may be represented by populations found in the one cuh and Choctawhatchee river drainage’s in southeastern Alabama and northwestern Florida.
HABITAT AND BIOLOGY: This schooling species occurs primarily in rivers and reservoirs and occasionally in moderate or large streams. Pflieger (1975) reports July spawnings in Missouri. We have encountered tuberculate adults running eggs and milt from April through June, indicating a protracted spawning season in Alabama. We have collected small, 1- to 3- inch highfins along sand and gravel bars in June and July as well as spent but still slightly tuberculate adults as late as August.
ORIGINAL DESCRIPTION:Rafinesque described the highfin carpsucker in 1820.
Velifer means sail bearer, referring to this species’ elongate dorsal fin.
