GOLDEN SHINER
Notemigonus crysoleucas
Species overview: The golden shiner is widely distributed from the Canadian
Maritime provinces, throughout the eastern and central United States, to South
America, and in many parts of the western United States. The golden shiner is
most often used as bait. Notemigonus means angled back,
and crysoleucas means golden-white.
Identification: Adults can reach sizes of seven to 10 inches,
and may live as long as eight years. Anglers sometimes catch larger adults while
fishing for other species. The golden shiner is deep-bodied with a small head.
It has gold-colored sides and an olive-brown back. The sides sometimes reflect
a silver color. The fins in the adult are yellow or light-olive, and silvery
in the young. The smallest young, those smaller than about four inches, appear
silvery all over, as do other shiners. Young golden shiners have a dark lateral
stripe that becomes fainter as the fish grows, until it is absent in adults.
The lateral line is curved noticeably downward.
The golden shiners body has cycloid scales, but the head has no scales.
It has four to six teeth in one or two rows on the pharyngeal arches. There
are no teeth in the mouth. The golden shiner has a single, spineless dorsal
fin with eight rays. The anal fin has 11 to 13 rays and is deeply curved.
The belly between the pelvic and anal fins is raised in a sharp keel that bears
no scales.
Habits: The golden shiner can be found in the quieter portions
of lakes, rivers and streams with clear water, a bottom of sand or organic debris,
and much aquatic vegetation.
Life history: Golden shiners spawn in late spring through about mid-summer
in water temperatures of 68 to 80 degrees. The female lays adhesive eggs in
submerged vegetation. One or two males usually pursue the female, pushing the
female with their snouts and moving in quick circles. Spawning males grow small
tubercles on the top and sides of the head, and on the lower jaw.
Golden shiners feed on zooplankton and midge pupae. They also consume small
mollusks, insect larvae, filamentous algae and terrestrial insects.
