Original post made by William Sipes(Riverrat) on August 17, 2002 River Chubs and Creek Chubs Identification: Anglers sometimes catch large river chubs while fishing for other species. River chubs attain lengths of six to nine inches. The river chub has small eyes and a long snout. The back is olive-brown, shading to silvery on the sides above a pale-yellowish belly. The head of large breeding males becomes swollen between and behind the eyes. The head has fewer than 40 large, sharp tubercles above the snout but below the eyes. The pectoral fins are somewhat rounded and blunt-tipped, and a fleshy barbel is present at the rear angle of the jaws. Identification: The creek chub may attain a length of 10 inches, but the length averages closer to four inches. The body is nearly cylindrical, tapering at the head and tail. The back is light to dark-olive, shading to silvery on the sides with purple-violet reflections above a silvery-white belly. The dorsal fin has a dark spot at the lower front corner. The head and body of breeding males are tinged with rose-purple, blue, yellow or orange. A single row of six to 12 large tubercles extends backward from the front of the snout to a point above and just behind each eye. Smaller tubercles are found on the gill cover and on the first six to eight rays of the pectoral fins. Young creek chubs are more silvery than adults. The young also have the spot on the dorsal fin. A narrow black band extends along the middle of each side from the eye to the caudal fin base. It ends in a dark spot.
