Many fishes in lotic systems rely on benthic fauna (i.e., aquatic insects and crustaceans) as a primary food source, including mottled sculpin (Cottus bardi), various darters (Etheostoma sp., Percina sp., and Ammocrypta pellucida) and sport-fishes (e.g., Salmonidae).
Two species not collected from Fall Creek but found elsewhere were white sucker (Catostomus commersonii) and blackside darter (Percina maeulata).
New localities for Notropis buchanani, Fundulus diaphanus menona, Aphredoderus sayanus, Ammocrypta pellucida, and Percina sciera have been recorded from the Western basin.
An ecological study of four darters of the genus Percina (Percidae) in the Kaskaskia River, Illinois.
Finescale Logperch, Percina microlepida, were present in Irvine Lake in the Santa Ana River drainage the early 1990s.
Mississippi's Pascagoula River drainage is home to the last known surviving populations of the pearl darter (Percina aurora), a small freshwater fish that measures just two-and-one-half inches long.
All other species were uncommon to rare (< 1% of total catch), including common carp (Cyprinus carpio), rock bass (Ambloplites rupestris), northern pike (Esox lucius), logperch (Percina caprodes), and smallmouth bass (Micropterus dolomieui).
Loss of unique genetic variation due to fishing pressure, habitat degradation, and hatchery stocking has been reported for Pacific cod (Gadus macrocephalus), leopard darter (Percina panterina), Japanese flounder (Paralichthys olivaceus), and American shad (Alosa sapidissima) (Grant and Stahl, 1988; Echelle et al., 1999; Brown et al., 2000; Sekino et al., 2003), and there is concern that a concentration of fishing effort in and around Chesapeake Bay could result in the loss of unique genetic variation in Atlantic menhaden.
ABSTRACT--Discovered in 1973, the snail darter (percina tanasi Etnier) was extirpated from Little Tennessee River upon completion of Tellico Dam in 1979.
In the 1970s while the snail darter (Percina tanasi) was focusing national attention on the Tellico Dam on the Little Tennessee River, another dam project was threatening two listed mussels slightly to the west on the Duck River.
