Hybridization between northern redbelly
dace, Phoxinus eos, finescale dace, Phoxinus neogaeus, and their hybrids in Upper Pierre Grey Lake, Alberta.
The enclosures with fish (F and FN treatments) were stocked with a hybrid redbelly
dace (Phoxinus eos x P.

Although the three fish species in this study occur in other areas in Oklahoma and the United States (Miller and Robison, 2004), the Arbuckle-Simpson springs provide specialized habitat for two cyprinids, Phoxinus erthyrogaster (southern redbelly
dace) and Nocomis asper (redspot chub) and a percid, Etheostoma microperca (least darter).

dace), but these species are morphologically distinct (Starnes and Jenkins, 1988).
Lake Erie has 14 unique species: the silver chub, bigeye chub, silverjaw minnow, ghost shiner, silver shiner, pugnose minnow, suckermouth minnow, southern redbelly
dace, brindled madtom, northern madtom, orangespotted sunfish, eastern sand darter, orangethroat darter and tubenose goby.
Two species and the one hybrid collected by Johnson but not found currently were common shiner (Luxilus cornutus), tadpole madtom (Noturus gyrinus) and northern redbelly
dace X finescale dace (Phoxinus eos X neogaeus).
Numerous individuals of Campostoma anomalum (central stoneroller), Luxilus cerasinus (crescent shiner) and Phoxinus oreas (mountain redbelly
dace) also schooled over the nest.
Only three fish species occurred in the study reach, Phoxinus erythrogaster (southern redbelly
dace), Campostoma anomalum (central stoneroller) and Etheostoma spectabile (orangethroat darter).
The southern redbelly
dace Phoxinus erythrogaster is a colorful, small to medium-sized minnow (55 to 65 mm SL; Starnes and Starnes, 1980) that is widely distributed within the upper Mississippi River Valley.
