Longnose shiners are small, long fish that are not longer than 58 to 65 mm. Grownup males are 34.9 mm long on average and females are 33.8 mm long on average. Their head is round and their nose is long and blunt. Their eyes are small and located high on their head. They have a lateral line running all the way form head to tail, and 34 to 37 scales along their lateral line. They are a sandy to straw color, and are usually pale yellow above the lateral line. They also have a thin stripe across the middle. They are usually white or silvery on their belly. Especially males have bright yellow fins in the breeding season. (Ross, 2001)
Longnose shiners live throughout the southeastern coastal states of the United States. They are found from just west of the Mississippi River in Louisiana to Florida. They live in Louisiana's Florida Parishes, north into the lower Ouachita River area in Louisiana and the lower part of the Yazoo River area in Mississippi, to the upper Altamaha River area in Georgia. They are also found in the Ocmulgee River system in Georgia and some groups live in in the upper Coosa River system and smaller rivers draining into the Alabama River. (Bart, et al., 1995; Douglas, 1974; Ross, 2001)
Longnose shiners live in free-flowing water with sandy bottoms like rivers. They can live in places that have currents, too. They often live in rivers with white, sandy stream bottoms and low to medium speed of water flow. They are often found along open sandbars. They are commonly found in areas where the edges of streams have plants with woody stems or brush. (Douglas, 1974; Heins and Clemmer, 1975; Jordan, 1989)
In longnose shiners, the size of the eggs changes with the size of the female. The same number of male and females are born. (Ross, 2001)
Scientists don't know much about the mating systems of longnose shiners.
Longnose shiners breed from March until October, and have more than one set of eggs in the same season. They often breed once at the beginning of the season and again around July. Females normally have 62 to 121 mature eggs per set, but can have anywhere from 15 to 129 eggs. Some longnose shiners can reproduce by the end of the first year. Females scatter eggs in the water and males fertilize them. (Mayden, 1992; Ross, 2001; Williams and Bonner, 2006)
Longnose shiners don't invest time or energy into their offspring after they scatter and fertilize the eggs. (Mayden, 1992)
Longnose shiners live about 1 to 2.5 years in the wild. Most don't survive their third winter. (Ross, 2001)
Longnose shiners recently adapted to life in flowing water. They latch onto surfaces like rocks with their mouth to prevent from being swept away. Longnose shiners generally feed during the day. (Adams, et al., 2003; Keplinger, 2007)
Scientists don't know much about the home range of longnose shiners.
Like all fish, longnose shiners have a sensory organ running from their head to tail called a lateral line. It helps them sense water currents and vibrations. They use their eyes and lateral line to get information about their environment.
Longnose shiners generally eating during the day. They mostly eat fly larvae and other insects living in the watre. The only insect they eat that lives on land are ants. Longnose shiners eat crustaceans like copepods and water fleas, and occasionally ostracods. They eat seeds of various flowering plants called sedges (Cyperaceae), and tiny algae plants called diatoms, desmids, and filamentous algae, as well as Fungi that live in the water. (Heins and Clemmer, 1975; Keplinger, 2007)
Longnose shiners eat several kinds of insects and plants and are prey for larger fish.
There are no known negative impacts of longnose shiners on humans.
Shiners are often used as bait by fishermen because they are shiny. (Steiner, et al., 2000)
