The Topeka shiner (Notropis topeka) is a North American species of cyprinid freshwater fish.
The Topeka shiner is a type of minnow that does not grow longer than a few inches. This minnow is a shiny silver color. Its main physical characteristic is the black colored stripe that runs along the side of the body.
It is distributed in the Mississippi River basin, from southern Minnesota and southeastern South Dakota south to central Missouri and southern Kansas.
The Topeka shiner lives mainly in prairie streams. In order for the Topeka shiner to survive the water must be cold and clear. The streams in which this Minnow lives are typically consistent and run year long. In cases in which the stream does dry up, the Topeka Shiner needs to find a new stream or permanent body of water to survive. Oxbow lakes are especially important habitat for Topeka shiners, as in faster moving bodies of water, they are easily picked off. [2]
The Topeka shiner was listed as Endangered by the U.S. Fish and Wildlife Service in 1998. The species is endangered primarily because of the water quality need. This species relies on clean water to survive. When the streams water quality changes the Topeka shiner has difficulty adjusting to the changes. The water quality can change due to both environmental and human impact. A main cause for the decline in population is human activity. The water quality changes and the minnow are impacted when natural plant life is taken away. Any type of construction such as road work, new homes and other types of development can affect the habitat in which the Topeka shiner lives.
In particular, the infilling of oxbow lakes due to agricultural runoff-induced erosion and channelization robbed the shiners of slow currents and vegetation to spawn in and hide from predators. [2] However, thanks to oxbow restoration efforts by the Iowa Topeka Shiner Recovery Partnership, comprising the Iowa Soybean Association, the United States Fish and Wildlife Service, the Practical Farmers of Iowa, and The Nature Conservancy of Iowa, the US Fish and Wildlife Service recommended that the Topeka shiners be downlisted to Threatened status in 2021. [3] [2] [4] Oxbow restoration can be as simple as digging out excess sediment and connecting rivers to oxbows. [2]
The woundfin is a species of minnow endemic to the Virgin River of the southwestern United States. It is the only species in the monotypic genus Plagopterus.
The Cahaba shiner is a rare species of cyprinid fish. It is endemic to Alabama in the United States, where it is limited to the Cahaba River. It is a federally listed endangered species of the United States.
The Cape Fear shiner is a North American species of freshwater fish in the family Cyprinidae. It is endemic to the central part of the state of North Carolina in the southeastern United States, and is only found in the shallow streams of the Cape Fear River basin. The fish is small and yellow with black lips and a black stripe that runs down the middle of the fish's side. This shiner is normally found in mixed schools with other minnow species. It is unique amongst its genus because it has elongated intestines that are specifically adapted to a primarily herbivorous diet. It can breed twice a year and normally lives for only two or three years in the wild. The males and females are normally similar in appearance but become different colors in the spawning season. This species of shiner was not discovered until 1962.
The Tar River spiny mussel or Tar River spinymussel is a species of freshwater mussel in the family Unionidae, the river mussels. It is endemic to North Carolina in the United States and expected to go extinct without human intervention. Under the Endangered Species Act of 1973, it is an endangered species.
Fusconaia cuneolus, the fine-rayed pigtoe pearly mussel or fine-rayed pigtoe, is a species of bivalve in the family Unionidae. It is native to Tennessee, Alabama, and Virginia in the United States, in each of which its population has declined severely. It is a federally listed endangered species of the United States.
The bridle shiner is a member of the minnow family (Cyprinidae). This species has been identified as being of Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).
The sand shiner is a widespread North American species of freshwater fish in the family Cyprinidae. Sand shiners live in open clear water streams with sandy bottoms where they feed in schools on aquatic and terrestrial insects, bottom ooze and diatoms.
The pugnose shiner is a species of ray-finned fish in the genus Notropis. It is in the family Cyprinidae which consists of freshwater carps and minnows. Cyprinidae is the largest fish family which consists of about 369 genera and 3,018 species. Its distribution has been decreasing due to the removal of aquatic plants in order to create swimming beaches and boating access in freshwater lakes and is now mostly found in Minnesota, Wisconsin, and Michigan.
The popeye shiner is a North American species of freshwater cyprinid fish.
The bigeye shiner is a species of ray-finned fish in the genus Notropis. This fish is a slender, silvery minnow with a dusky lateral stripe and a maximum total length of about 80 mm (3.1 in). Its distinct characteristic is its large-diameter eyes. It is a common species in upland streams of the middle Mississippi River system. Bigeye shiners prefer warm, quiet pools with clear water and silt-free substrates. Siltation, channelization, and gravel dredging are all threats to bigeye shiner populations. During spawning season, typically late April to August, bigeye shiners have several clutches of eggs. State agencies and the EPA have both played a role in the surveying of bigeye shiner populations. Populations have decreased in Ohio due mostly to habitat destruction. In addition to habitat destruction by humans, habitat alteration of the small streams and dried pools has also had a significant effect on abundance. Rivers and streams should not be channelized or modified in any way, which is becoming an increasingly popular trend in urban locations. Agricultural areas and properties within the watershed should adhere to regulations to prevent runoff into the streams.
The rainbow shiner is a North American species of ray-finned fish in the genus Notropis.
The spottail shiner or spottail minnow is a small- to medium-sized freshwater minnow. It can be found as far north as Canada and as far south as the Chattahoochee River in Georgia. These shiners live in lakes, rivers, and creeks. They occupy the rocky or sandy shorelines and bottoms of the water. One of the defining features of a spottail shiner is the black spot found at the base of the caudal fin. These shiners generally spawn from late June through July.
The carmine shiner is a freshwater fish species. In Manitoba, it was once known as the rosyface shiner. Based mostly on zoogeographic data, it is currently classified as a distinct species within the rosyface shiner species complex. The carmine shiner is a member of the Minnow family, Cyprinidae. It has the following characteristics and distinguishing features:
The weed shiner is a North American species of freshwater fish in the cyprinid genus Notropis. Prior to 1958, this species was named Notropis roseus.
The plains minnow is one of the 324 fish species found in central United States. It is a large minnow that was once a common bait fish. The plains minnow requires shallow, slow-moving streams to complete its life cycle. Pollution, dams, and introduced sport fish have caused populations to decline.
The bigmouth shiner, is one of the 324 fish species found in Tennessee. It is a common minnow species found in the midwest region, but found as far as the east coast. There has been little information researched about this minnow outside of the general body plan and habitat. They are often found along with common shiner in streams.
The bleeding shiner is a freshwater ray-finned minnow in the family Leuciscidae, which was recently changed to distinguish between North American and Asian minnows. It occurs in tributaries of Ozark-draining tributaries of the Missouri, and Mississippi rivers in southern Missouri and northeastern Arkansas. Its preferred habitat is rocky and sandy pools and runs of headwaters, creeks and small rivers.
