The shadow bass (Ambloplites ariommus) is a species of freshwater fish in the sunfish family (Centrarchidae) of order Centrarchiformes.

[4] The shadow bass' native range includes the southeastern United States from the Apalachicola River drainage in Georgia to the lower Mississippi basin in Louisiana.

[7] Undercut banks and woody debris in small to medium-sized rivers and streams are also preferred habitat.

Factors by humans that might attribute to population decline of the shadow bass channelization, sedimentation from logging, and habitat encroachment.

The breeding males show obvious darkening to the membranes of the pelvic and anal fins while these remain yellow or white in the females.

[10] It was first formally described in 1936 by Peter Viosca Jr. with the type locality given as Little Bogue Falaya Creek, 3 miles north of Covington, Louisiana.

In Missouri, however, where shadow bass has a demand in the game fish market, biologists are conducting population studies using mark and recapture methods and information for anglers to provide data to determine what, if any, angling restrictions need to apply to shadow bass fishing.

[9] The IGFA all tackle world record for the shadow bass stands at 0.82 kg (1 lb 13 oz) caught from the Spring River in Arkansas.
