Golden shiners, Notemigonus crysoleucas, are widely distributed throughout North America. Their native range includes the Atlantic drainage basin from Nova Scotia south to southern Texas, the Great Lakes basin, and the Mississipi River drainage basin from Alberta Canada, to Wyoming, Montana and Oklahoma. (Luna, 2005)
Golden shiners occupy a variety of deep water habitats, including vegetated lakes, ponds, swamps and pools of creeks and small to medium rivers to a depth of 10 m (Luna 2005). As they feed primarily on zooplankton and phytoplankton, they are typically found in slow moving or stagnant waters (Magnin, Murawska and Clement, 1978). (Luna, 2005; Magnin, et al., 1978)
Golden shiners are thin, deep bodied minnows with small, upturned mouths. During the breeding season, males turn a deep golden color. A greatly decurved lateral line and a fleshy pre-anal keel distinguish golden shiners from other members of the minnow family (Cyprinidae) (Dobie, Meehean, and Washburn, 1948). Golden shiners are relatively small, and reach a maximum length of 30 cm (Page and Burr, 1991). (Dobie, et al., 1948; Page and Burr, 1991)
Golden shiner eggs hatch when the water temperature reaches 20 degrees Celsius (Cross, 1967). Larvae have a yolk-sac and remain near the bottom until the sac is absorbed. These larvae average 4.2 mm in length. Larvae 5-10 mm in length remain near the water surface at the edge of the littoral zone. Larvae 10-30 mm in length organize into schools amd inhabit vegetated areas of the littoral zone (Faber, 1980). Females grow faster than males and reach larger sizes (Cooper, 1936). (Cooper, 1936; Cross, 1967; Faber, 1980)
Golden shiners typically spawn from May through August. Spawning aggregations form and spawning occurs over algae or aquatic plants. Once released, the eggs stick to vegetation. (Cross, 1967)
Eggs are incubated for a period of 4 to 7 days, and maximum fecundity is 200,000. Golden shiners are repeat spawners and may spawn 4 to 5 times per season (Manusuet and Hardy 1967). Sexual maturity generally occurs at 1 year, however some do not mature until the second year, especially in cooler waters (Dobie, Mehean and Washburn, 1948). (Dobie, et al., 1948; Mansuet and Hardy, 1967)
Golden shiners invest no parental care in their eggs or young after egg-laying. (Dobie, et al., 1948)
Adult golden shiners typically reach an age of 3 to 6 years. The maximum age reached by this species is 8 years. (Carlander, 1969)
Golden shiners are social and are found in groups (schools) thougout life. These fish feed in the littoral (nearshore) zone within one hour of sunset. As the sun sets, schools break up and individuals move into open water. (Hall, et al., 1979; Mansuet and Hardy, 1967)
Golden shiners detect water movement through their lateral line and probably also rely on visual cues to find food and avoid predators. Little is known about other ways they sense their environment or forms of communication.
Golden shiners are omnivorous and crepuscular planktivores. Their diet mainly consists of zooplankton, phytoplankton, and microcrustaceans. They pick off plankton one at at time and generally occupy slower moving waters. Additionally, Odonata nymphs form a minor portion of their diet. (Hall, et al., 1979; Magnin, et al., 1978)
Golden shiners form schools as a way to decrease their individual likelihood of being taken by the many larger fish species that prey on them.
Golden shiners feed on zooplankton and phytoplankton, keeping plankton levels below eutrophication levels. Pleistophora ovarie, an obligate intracellular parasite, causes egg mortality and reduced egg production in golden shiners. They are also important as prey of larger, predatory fish in the ecosystems in which they live. (Hall, et al., 1979; Nagel and Summerfelt, 1977)
Golden shiners are an important bait species for game fish, helping to ensure healthy populations of economically important fish species. They are also used as a standard in toxicology bioassesments (Dobie, Meehan et al, 1956). (Dobie, et al., 1948)
Golden shiners have been widely indroduced outside of their native range because they are used as bait and are sometimes released from bait buckets.
Golden shiners are fairly common and are not currently protected by law.
