The pugnose shiner (Notropis anogenus) 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. [2] 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. [3]

Distribution

The pugnose shiner is a non-abundant species of Notropis and within the United States, it is distributed across parts of Minnesota, Wisconsin, and Michigan. It is native to North America and its historic range was from eastern Ontario and Western New York to North Dakota, Illinois, Indiana, and Ohio, ending in the St. Lawrence River drainage. [3] The population that was once in North Dakota is now thought to be extirpated due to turbidity and uprooted vegetation within the freshwater lakes and streams. This minnow can also be found in a few areas of Canada but those ranges have also decreased throughout time so now the Canadian population mostly lies within Ontario. [1]

Description

The pugnose shiner is a type of minnow that can live for up to 3 years and is able to reach sizes between 20-60mm, although it is about 47mm on average. It has a lateral dark stripe on the side of its body that runs from the tip of the caudal fin, through the eye, and to the nose tip. It has a small, terminal mouth angled upwards, giving it the pug-nose appearance. The abdominal region is yellow, and it has a clear-colored tail fin. [4] Each fish has about 34-37 round, silver cycloid scales covering its body which has a fusiform shape to help the pugnose shiner swim against the constant stream currents. The pelvic fins are in the abdominal position. Because it is a ray-finned species, the fin rays are used as elements to support the skeletal features. [5] The pugnose shiner has an 8-rayed dorsal fin on top of the dusky-colored back, a feature separating it from the pugnose minnow. This fish is also the only Minnesota Notropis species that has a darkly pigmented peritoneum. [6]

Ecology

Although it is not an abundant species, the pugnose shiner can be found inhabiting weedy, clear lakes and slow-moving streams throughout its temperate, freshwater range. [4] When temperatures are warmer, this fish is found in shallow water but when it cools down in the winter months, it is found in waters as deep as 2 meters. [1] The pugnose shiner is a great indicator for healthy ecosystems because it is very sensitive to its environment because it is intolerant to turbidity. Their diets tend to consist of filamentous algae and cladocera (water fleas), eggs, insects, worms, and anything else under 2mm. Their predators consist of any omnivorous fish that is larger than this shiner. [4] They are mid to low level consumers and therefore take little part in the transfer of nutrients. [7]

Reproduction

The pugnose shiner reaches sexual maturity between the ages of 1 and 2 for both the male and female genders. They are an oviparous species and spawning and fertilization occur in summer between May and July. The female distributes her eggs in shallow water in areas of dense vegetation in which she lays between 530 and 1275 eggs. Once the eggs are fertilized, they generally hatch within one or two days. This species does not spend energy in parental investment so after the eggs are laid and fertilized, the male and female leave the eggs. [4] In pugnose shiners, sexual dimorphism occurs and they have a polygynandrous mating system, meaning that both males and females have multiple mates. Sexes are physically different in that the males' pelvic fins go beyond the anal openings while the females' don't. [8]

Conservation status

The conservation status of the pugnose shiner has been changing quite a bit in the past few years. This is partly because its status is dependent on where the species population is. In Canada, the pugnose shiner is currently listed as endangered but the status varies by state in the United States. This species has been declining through the upper midwest because of turbidity, decreasing vegetation, and invasive species within its home. There are multiple subpopulations of pugnose shiner but there is limited connection between the different populations because of low dispersal potential. [9] It was listed as Near Threatened in 2010 but as of 2014, the pugnose shiner has been of Least Concern status. It has patterns of population decline so it is continually on concern conservation attention. [1]

Etymology

The pugnose shiner genus name Notropis comes from Greek descent and it is a name given to shriveled-like specimens. It translates to the words "back keel". The species name anogenus is also from Greek descent and it translates to "without a chin". [3]

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 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 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. 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 blackchin shiner is an abundant North American species of freshwater fish from the family Cyprinidae. Described by Edward Drinker Cope in 1865, it is not a well-known species. It is a close relative of the blacknose shiner. Chiefly occurring now in the Great Lakes and occasionally in upper Mississippi River drainages, the blackchin once ranged commonly as far south as Illinois and Ohio. This fish resides over sandy bottoms in cool waters that provide a lot of cover for the small minnow. Omnivorous, it eats worms and small arthropods as well as plant material. Blackchin shiners are unique because of their anatomical features, such as the black coloring, the incomplete lateral line, and a distinctive dental arrangement.

<span class="mw-page-title-main">Mimic shiner</span> Species of fish

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.
