The spottail shiner or spottail minnow (Notropis hudsonius) 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.
Spottail shiners are typically small to medium-sized minnows. The average size ranges from around 2 to 3 inches (5.1 to 7.6 cm). They can reach up to 6 inches (15 cm) at their maximum length. [2] They have a slightly elongate, compressed body with a horizontal, sub-terminal mouth. The defining feature of a spottail shiner is the distinct black spot at the base of the caudal fin. [3] The lower edge of the caudal fin can be white in color with all of the other fins lacking pigment. [3] The dorsal fin sits directly above the pelvic fins. The dorsal side of this shiner can range from a silvery to pale green or olive color, whereas the ventral side is white. [3] The spottail shiner has a complete lateral line running horizontally along its sides. [4]
Notropis species mainly live in streams and rivers but can be found in larger lakes. [5] They can be found 3 to 60 feet (0.91 to 18.29 m) deep, on substrates of sand and gravel. [2] The spottail shiner is one of more common species of the genus Notropis. [5] Spottail shiners are native to Canada and the United States. [5] They are found in the St. Lawrence River in Quebec, Chattahoochee River and Altamaha River in Georgia, the Mackenzie River basin in Canada, Ohio Illinois, the Hudson Bay, some lakes throughout Montana, and the Great Lakes. [6] They can also be found in some lakes in the upper northeast region of the United States. [5] These spottail shiners seem to have only occupied the areas of Canada and United States that they are currently distributed today, with the exception of Montana. It seems that the shiners have been introduced in lakes through Montana in order to become bait for some of the larger gaming fish such as the walleye. [3]
Spottail shiners are generally omnivorous fish that feed on plants, aquatic invertebrate, and zoobenthos. [6] Zoobenthos are the invertebrates that occupy the benthos of the riverbeds and lakebeds. This shiner is said to feed on green algae, plant debris, vascular plants, water fleas, caddis flies, mayflies, nematocerans, and the remains of macroinvertabrates. [6] Given the small size of the fish it does not usually prey on other fish species. The spottail shiner obtains much of its food by scavenging on the floor of the river, lakes, and streams that it occupies.
Given the small size of spottail shiners, many different species of fish prey upon them. Some predators include rainbow trout, coho salmon, chinook salmon, northern pike, walleye, brown trout, lake trout (Salvelinus namaycush), and bluefish (Pomatomus saltatrix). [6]
The spottail shiner mainly competes with species that have the same diet and live in the areas. These competitors can include other species of shiners, yellow perches, or white perches. [7]
There are certain abiotic factors that determine spottail shiners' habitat. The spottail shiner's highest activity levels are usually seen in areas where the pH value range between 5.6 and 6.6, maximizing at a pH value around 6.1. [8] Spottail shiners generally live in waters that temperatures range from 10 to 50 °C (50 to 122 °F). [6]
The life history of the spottail shiner has not been studied much. Spottail shiners breeding season usually occurs in the summertime during the months of June and July. [6] They are thought to spawn in the sandy bottoms and shorelines of the rivers, lakes, and creeks where they live. Females are thought to produce anywhere from 100 to 2,600 eggs per spawning event. The mature age of a spottail shiner is around one or two years of age. The maximum age recorded for a spottail shiner to live is 5 years. [6] Since there has not been a lot of research involving the life history of the spottail shiner not a lot of information can be given on spawning and reproduction.
Spottail shiners are currently listed as of least concern. These shiners are not vulnerable in the wild yet. [6] The primary causes for death is being preyed upon, pollution of their natural habitat, and parasites. Minnows are used as bait for game fishing. [9] These shiners are caught and used as bait fish throughout the area they occupy. [9] They are one of the most popular minnow used to lure walleyes. [3] Their shiny scales and small bodies attract specific species of game fish that anglers frequently try to catch. Currently there are conservation agencies at the state-level protecting these shiners from being harvested for fish bait. Pollution of many different toxic chemicals into the areas that these shiners live is one of the main causes of death. [10] It is found that water pollution from wastewater and runoff affect the immune system of spottail shiners. [11] There are certain parasites that also affect the life of these shiners. The parasites are also found to affect the immune system in spottail shiners. [11]
Minnow is the common name for a number of species of small freshwater fish, belonging to several genera of the families Cyprinidae and Leuciscidae. They are also known in Ireland as pinkeens.
The emerald shiner is one of hundreds of small, silvery, slender fish species known as shiners. The identifying characteristic of the emerald shiner is the silvery emerald color on its sides. It can grow to 3.5 inches in length and is found across North America from Canada to the Gulf of Mexico, commonly in large, deep lakes and rivers, though sometimes in smaller bodies of water as well. It feeds on small organisms such as zooplankton and insects, congregating in large groups near the surface of the water. It is a quite common fish and is often used as a bait fish.
The Tennessee shiner is a species of fish in the family Cyprinidae, the carps and minnows. It is native to the southeastern 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 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 mimic shiner is a species of North American cyprinid freshwater fish in the genus Notropis. The genus Notropis is commonly known as the eastern shiners. It is native to areas of the Hudson Bay drainage, Great Lakes drainage, much of the Mississippi River basin including areas of Tennessee, Virginia, North Carolina, and regions of the Gulf of Mexico extending from Mobile Bay to the drainage of Texas. However, this particular species can be found in other places such as the Atlantic Coast drainage in Connecticut and Housatonic rivers. This genus is usually characterized by almost all having a complete lateral line, 8 dorsal fin rays, a premaxillae protactile, and a silvery or speckled peritoneum. As the common name indicates, this species is difficult to classify in the wild because it looks similar to many other shiners. In fact, some even hypothesize that this species is actually a complexity of many cryptic species. While this is the case, it is important to take more caution to not misidentify this species and to understand its impact on introduced areas.
The ironcolor shiner is a species of freshwater ray-finned fish from the family Cyprinidae, the minnows and carps. It is a widespread species in streams and rivers in eastern North America.
The scarlet shiner is a freshwater fish native to the eastern United States.
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.
Percopsis omiscomaycus, also known as the trout-perch, the grounder or the sand minnow, is one of two species in the family Percopsidae. Its name comes from the Greek root words perc, meaning perch and opsi meaning appearance. The species name omiscomaycus is thought to be derived from a Native American word meaning trout. These are freshwater fish that prefer clear to slightly turbid water, and are found in rivers and lakes throughout North America. They are a generally small fish found in deep waters by day, but which migrate to shallower waters at night.They are most often seen washed up on beaches and are rarely seen alive or correctly identified. The trout-perch possess characteristics similar to both the trout and the perch. They are an important source of food for many predator fish such as walleye, northern pike, and lake trout. They are not a major human fishery, but are occasionally used as a bait fish.
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.
