The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Michigan is a state in the Great Lakes and Midwestern regions of the United States. The state's name, originates from the Ojibwe word mishigamaa, meaning "large water" or "large lake". With a population of about 10 million, Michigan is the tenth most populous of the 50 United States, with the 11th most extensive total area, is the largest state by total area east of the Mississippi River, its capital is Lansing, its largest city is Detroit. Metro Detroit is among the nation's largest metropolitan economies. Michigan is the only state to consist of two peninsulas; the Lower Peninsula is noted as shaped like a mitten. The Upper Peninsula is separated from the Lower Peninsula by the Straits of Mackinac, a five-mile channel that joins Lake Huron to Lake Michigan; the Mackinac Bridge connects the peninsulas. The state has the longest freshwater coastline of any political subdivision in the world, being bounded by four of the five Great Lakes, plus Lake Saint Clair; as a result, it is one of the leading U.
S. states for recreational boating. Michigan has 64,980 inland lakes and ponds. A person in the state is never more than six miles from a natural water source or more than 85 miles from a Great Lakes shoreline; the area was first occupied by a succession of Native American tribes over thousands of years. Inhabited by Natives, Métis, French explorers in the 17th century, it was claimed as part of New France colony. After France's defeat in the French and Indian War in 1762, the region came under British rule. Britain ceded this territory to the newly independent United States after Britain's defeat in the American Revolutionary War; the area was part of the larger Northwest Territory until 1800, when western Michigan became part of the Indiana Territory. Michigan Territory was formed in 1805, but some of the northern border with Canada was not agreed upon until after the War of 1812. Michigan was admitted into the Union in 1837 as a free one, it soon became an important center of industry and trade in the Great Lakes region and a popular immigrant destination in the late 19th and early 20th centuries.
Although Michigan developed a diverse economy, it is known as the center of the U. S. automotive industry, which developed as a major economic force in the early 20th century. It is home to the country's three major automobile companies. While sparsely populated, the Upper Peninsula is important for tourism thanks to its abundance of natural resources, while the Lower Peninsula is a center of manufacturing, agriculture and high-tech industry; when the first European explorers arrived, the most populous tribes were Algonquian peoples, which include the Anishinaabe groups of Ojibwe, Odaawaa/Odawa, the Boodewaadamii/Bodéwadmi. The three nations co-existed peacefully as part of a loose confederation called the Council of Three Fires; the Ojibwe, whose numbers are estimated to have been between 25,000 and 35,000, were the largest. The Ojibwe were established in Michigan's Upper Peninsula and northern and central Michigan, inhabited Ontario and southern Manitoba, Canada; the Ottawa lived south of the Straits of Mackinac in northern and southern Michigan, but in southern Ontario, northern Ohio and eastern Wisconsin.
The Potawatomi were in southern and western Michigan, in addition to northern and central Indiana, northern Illinois, southern Wisconsin, southern Ontario. Other Algonquian tribes in Michigan, in the south and east, were the Mascouten, the Menominee, the Miami, the Sac, the Fox; the Wyandot were an Iroquoian-speaking people in this area. French voyageurs and coureurs des bois settled in Michigan in the 17th century; the first Europeans to reach what became Michigan were those of Étienne Brûlé's expedition in 1622. The first permanent European settlement was founded in 1668 on the site where Père Jacques Marquette established Sault Ste. Marie, Michigan as a base for Catholic missions. Missionaries in 1671–75 founded outlying stations at Saint Ignace and Marquette. Jesuit missionaries were well received by the area's Indian populations, with few difficulties or hostilities. In 1679, Robert Cavelier, Sieur de la Salle built Fort Miami at present-day St. Joseph. In 1691, the French established a trading post and Fort St. Joseph along the St. Joseph River at the present-day city of Niles.
In 1701, French explorer and army officer Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit or "Fort Pontchartrain on-the-Strait" on the strait, known as the Detroit River, between lakes Saint Clair and Erie. Cadillac had convinced King Louis XIV's chief minister, Louis Phélypeaux, Comte de Pontchartrain, that a permanent community there would strengthen French control over the upper Great Lakes and discourage British aspirations; the hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent and named it Fort Pontchartrain. Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of the first European women to settle in what was considered the wilderness of Michigan; the town became a major fur-trading and shipping post. The Église de Saint-Anne was founded the same year. While the original building does not survive, the congregation remains active. Cadillac departed to serve as the French governor of Louisiana from 1710 to 1716.

A river is a natural flowing watercourse freshwater, flowing towards an ocean, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, brook and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the hydrological cycle. Potamology is the scientific study of rivers, while limnology is the study of inland waters in general. Most of the major cities of the world are situated on the banks of rivers, as they are, or were, used as a source of water, for obtaining food, for transport, as borders, as a defensive measure, as a source of hydropower to drive machinery, for bathing, as a means of disposing of waste.
A river begins at a source, follows a path called a course, ends at a mouth or mouths. The water in a river is confined to a channel, made up of a stream bed between banks. In larger rivers there is also a wider floodplain shaped by flood-waters over-topping the channel. Floodplains may be wide in relation to the size of the river channel; this distinction between river channel and floodplain can be blurred in urban areas where the floodplain of a river channel can become developed by housing and industry. Rivers can flow down mountains, through valleys or along plains, can create canyons or gorges; the term upriver refers to the direction towards the source of the river, i.e. against the direction of flow. The term downriver describes the direction towards the mouth of the river, in which the current flows; the term left bank refers to the left bank in the direction of right bank to the right. The river channel contains a single stream of water, but some rivers flow as several interconnecting streams of water, producing a braided river.
Extensive braided rivers are now found in only a few regions worldwide, such as the South Island of New Zealand. They occur on peneplains and some of the larger river deltas. Anastamosing rivers are quite rare, they have multiple sinuous channels carrying large volumes of sediment. There are rare cases of river bifurcation in which a river divides and the resultant flows ending in different seas. An example is the bifurcation of Nerodime River in Kosovo. A river flowing in its channel is a source of energy which acts on the river channel to change its shape and form. In 1757, the German hydrologist Albert Brahms empirically observed that the submerged weight of objects that may be carried away by a river is proportional to the sixth power of the river flow speed; this formulation is sometimes called Airy's law. Thus, if the speed of flow is doubled, the flow would dislodge objects with 64 times as much submerged weight. In mountainous torrential zones this can be seen as erosion channels through hard rocks and the creation of sands and gravels from the destruction of larger rocks.
A river valley, created from a U-shaped glaciated valley, can easily be identified by the V-shaped channel that it has carved. In the middle reaches where a river flows over flatter land, meanders may form through erosion of the river banks and deposition on the inside of bends. Sometimes the river will cut off a loop, shortening the channel and forming an oxbow lake or billabong. Rivers that carry large amounts of sediment may develop conspicuous deltas at their mouths. Rivers whose mouths are in saline tidal waters may form estuaries. Throughout the course of the river, the total volume of water transported downstream will be a combination of the free water flow together with a substantial volume flowing through sub-surface rocks and gravels that underlie the river and its floodplain. For many rivers in large valleys, this unseen component of flow may exceed the visible flow. Most but not all rivers flow on the surface. Subterranean rivers flow underground in caverns; such rivers are found in regions with limestone geologic formations.
Subglacial streams are the braided rivers that flow at the beds of glaciers and ice sheets, permitting meltwater to be discharged at the front of the glacier. Because of the gradient in pressure due to the overlying weight of the glacier, such streams can flow uphill. An intermittent river only flows and can be dry for several years at a time; these rivers are found in regions with limited or variable rainfall, or can occur because of geologic conditions such as a permeable river bed. Some ephemeral rivers flow during the summer months but not in the winter; such rivers are fed from chalk aquifers which recharge from winter rainfall. In England these rivers are called bournes and give their name to places such as Bournemouth and Eastbourne. In humid regions, the location where flow begins in the smallest tributary streams moves upstream in response to precipitation and downstream in its absence or when active summer vegetation diverts water for evapotrans
Cheboygan is a city in the U. S. state of Michigan. As of the 2010 census, the city population was 4,876, it is the county seat of Cheboygan County. The name of the city shares the name of the county and has its origin from the Cheboygan River, although the precise meaning is no longer known, it may have come from an Ojibwe word zhaabonigan meaning "sewing needle". Alternatively, the origin may have been "Chabwegan," meaning "a place of ore."The city is at the mouth of the Cheboygan River on Lake Huron. U. S. Highway 23 connects with Interstate 75 at Mackinaw City and the Mackinac Bridge, about 15 miles to the northwest. Rogers City is about 41 miles to the southeast. M-27 runs south from the city along the north shore of Mullett Lake to I-75 at Indian River about 18 miles to the southwest. M-33 runs due south along the east shore of Mullett Lake to M-68 about 20 miles to the south. Cheboygan was an Ojibwe settlement. In 1844, Jacob Sammons, a cooper from Fort Mackinac, chose the old native camping ground as the site for his cabin.
He recruited other settlers, a post office named "Duncan" was established in 1846. It was made the county seat in 1853. Duncan or Duncan City was given a post office in 1850 as a result of the building of sawmills in this area. Duncan was made the county seat in 1853 and the location of the federal land office in 1855; the county seat shifted to Cheboygan in about 1870. Duncan was included within the expanded boundaries of Cheboygan; the area became known as Cheboygan in 1870. It was incorporated as a village in 1871. Rail maps in 1876 show planned rail service for Cheboygan, but due to various setbacks, rail did not arrive there until 1881. There was a theater built in town in 1877. Cheboygan was incorporated as a city in 1889. In 1890, Cheboygan became the home port for ferryboats to nearby Bois Blanc, an island in the Straits of Mackinac; the Kristen D is a ferry which operates between Bois Blanc Island. Early in the 20th century, it was home to Flagler. In 1944, Cheboygan became the home port of the former U.
S. Coast Guard cutter and icebreaker Mackinaw, serving from 1944 to 2006. Beginning in 2006, the port continued this role as the home dock of the new Mackinaw, a successor cutter.

Fishing is the activity of trying to catch fish. Fish are caught in the wild. Techniques for catching fish include hand gathering, netting and trapping. “Fishing” may include catching aquatic animals other than fish, such as molluscs, cephalopods and echinoderms. The term is not applied to catching farmed fish, or to aquatic mammals, such as whales where the term whaling is more appropriate. In addition to being caught to be eaten, fish are caught as recreational pastimes. Fishing tournaments are held, caught fish are sometimes kept as preserved or living trophies; when bioblitzes occur, fish are caught and released. According to the United Nations FAO statistics, the total number of commercial fishermen and fish farmers is estimated to be 38 million. Fisheries and aquaculture provide direct and indirect employment to over 500 million people in developing countries. In 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms.
Fishing is an ancient practice that dates back to at least the beginning of the Upper Paleolithic period about 40,000 years ago. Isotopic analysis of the skeletal remains of Tianyuan man, a 40,000-year-old modern human from eastern Asia, has shown that he consumed freshwater fish. Archaeology features such as shell middens, discarded fish bones, cave paintings show that sea foods were important for survival and consumed in significant quantities. Fishing in Africa is evident early on in human history. Neanderthals were fishing by about 200,000 BC to have a source of food for their families and to trade or sell. People could have developed basketry for fish traps, spinning and early forms of knitting in order to make fishing nets to be able to catch more fish in larger quantities. During this period, most people lived a hunter-gatherer lifestyle and were, of necessity on the move. However, where there are early examples of permanent settlements such as those at Lepenski Vir, they are always associated with fishing as a major source of food.
The British dogger was an early type of sailing trawler from the 17th century, but the modern fishing trawler was developed in the 19th century, at the English fishing port of Brixham. By the early 19th century, the fishermen at Brixham needed to expand their fishing area further than before due to the ongoing depletion of stocks, occurring in the overfished waters of South Devon; the Brixham trawler that evolved there was of a sleek build and had a tall gaff rig, which gave the vessel sufficient speed to make long distance trips out to the fishing grounds in the ocean. They were sufficiently robust to be able to tow large trawls in deep water; the great trawling fleet that built up at Brixham, earned the village the title of'Mother of Deep-Sea Fisheries'. This revolutionary design made large scale trawling in the ocean possible for the first time, resulting in a massive migration of fishermen from the ports in the South of England, to villages further north, such as Scarborough, Grimsby and Yarmouth, that were points of access to the large fishing grounds in the Atlantic Ocean.
The small village of Grimsby grew to become the largest fishing port in the world by the mid 19th century. An Act of Parliament was first obtained in 1796, which authorised the construction of new quays and dredging of the Haven to make it deeper, it was only in the 1846, with the tremendous expansion in the fishing industry, that the Grimsby Dock Company was formed. The foundation stone for the Royal Dock was laid by Albert the Prince consort in 1849; the dock covered 25 acres and was formally opened by Queen Victoria in 1854 as the first modern fishing port. The elegant Brixham trawler spread across the world. By the end of the 19th century, there were over 3,000 fishing trawlers in commission in Britain, with 1,000 at Grimsby; these trawlers were sold to fishermen including from the Netherlands and Scandinavia. Twelve trawlers went on to form the nucleus of the German fishing fleet; the earliest steam powered fishing boats first appeared in the 1870s and used the trawl system of fishing as well as lines and drift nets.
These were large boats 80–90 feet in length with a beam of around 20 feet. They travelled at 9 -- 11 knots; the earliest purpose built fishing vessels were designed and made by David Allan in Leith, Scotland in March 1875, when he converted a drifter to steam power. In 1877, he built. Steam trawlers were introduced at Hull in the 1880s. In 1890 it was estimated; the steam drifter was not used in the herring fishery until 1897. The last sailing fishing trawler was built in 1925 in Grimsby. Trawler designs adapted as the way they were powered changed from sail to coal-fired steam by World War I to diesel and turbines by the end of World War II. In 1931, the first powered drum was created by Laurie Jarelainen; the drum was a circular device, set to the side of the boat and would draw in the nets. Since World War II, radio navigation aids and fish finders have been used; the first trawlers fished over the side, rather than over the stern. The first purpose built stern trawler was Fairtry built in 1953 at Scotland.
The ship was much larger than any other trawlers in operation and inaugurated the era of the'super trawler'. As the ship pulled its nets over the stern, it could lift out a much greater haul of up to 60 tons; the ship served as a basis for the expansion of'su
Lake Huron is one of the five Great Lakes of North America. Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as its westerly counterpart, to which it is connected by the 5-mile-wide, 20-fathom-deep Straits of Mackinac, it is shared on the north and east by the Canadian province of Ontario and on the south and west by the state of Michigan in the United States. The name of the lake is derived from early French explorers who named it for the Huron people inhabiting the region; the Huronian glaciation was named due to evidence collected from Lake Huron region. The northern parts of the lake include the North Georgian Bay. Across the lake to the southwest is Saginaw Bay; the main inlet is the St. Marys River, the main outlet is the St. Clair River. By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of 23,007 square miles — of which 9,103 square miles lies in Michigan. By volume however, Lake Huron is only the third largest of the Great Lakes, being surpassed by Lake Michigan and Lake Superior.
When measured at the low water datum, the lake contains a volume of 850 cubic miles and a shoreline length of 3,827 mi. The surface of Lake Huron is 577 feet above sea level; the lake's average depth is 32 fathoms 3 feet. It has a greatest breadth of 183 statute miles. Cities with over 10,000 people on Lake Huron include Sarnia, the largest city on Lake Huron, Saugeen Shores in Canada and Bay City, Port Huron, Alpena in the United States. A large bay that protrudes northeast from Lake Huron into Ontario, Canada, is called Georgian Bay. A notable feature of the lake is Manitoulin Island, which separates the North Channel and Georgian Bay from Lake Huron's main body of water, it is the world's largest lake island. Major centres on Georgian Bay include Owen Sound, Wasaga Beach, Midland, Port Severn and Parry Sound. A smaller bay that protrudes southwest from Lake Huron into Michigan is called Saginaw Bay. Historic High Water The lake fluctuates from month to month with the highest lake levels in October and November.
The normal high-water mark is 2.00 feet above datum. In the summer of 1986, Lakes Michigan and Huron reached their highest level at 5.92 feet above datum. The high-water records began in February 1986 and lasted through the year, ending with January 1987. Water levels ranged from 3.67 to 5.92 feet above Chart Datum. Historic Low Water Lake levels tend to be the lowest in winter; the normal low-water mark is 1.00 foot below datum. In the winter of 1964, Lakes Michigan and Huron reached their lowest level at 1.38 feet below datum. As with the high-water records, monthly low-water records were set each month from February 1964 through January 1965. During this twelve-month period, water levels ranged from 1.38 to 0.71 feet below Chart Datum. The Great Lakes Circle Tour is a designated scenic road system connecting all the Great Lakes and the St. Lawrence River. Lake Huron has the largest shore line length of any of the Great Lakes, counting its 30,000 islands. Lake Huron is separated from Lake Michigan, which lies at the same level, by the 5-mile-wide, 20-fathom-deep Straits of Mackinac, making them hydrologically the same body of water.
Aggregated, Lake Huron-Michigan, at 45,300 square miles, "is technically the world's largest freshwater lake." When counted separately, Lake Superior is 8,700 square miles higher. Lake Superior drains into the St. Marys River which flows southward into Lake Huron; the water flows south to the St. Clair River, at Port Huron and Sarnia, Ontario; the Great Lakes Waterway continues thence to Lake St. Clair. Like the other Great Lakes, it was formed by melting ice as the continental glaciers retreated toward the end of the last ice age. Before this, Lake Huron was a low-lying depression through which flowed the now-buried Laurentian and Huronian Rivers; the Alpena-Amberley Ridge is an ancient ridge beneath the surface of Lake Huron, running between Alpena and Point Clark, Ontario. About 9,000 years ago, when water levels in Lake Huron were about 100 m below today's levels, the ridge was exposed and the land bridge was used as a migration route for large herds of caribou. Since 2008, archaeologists have discovered at least 60 stone constructions along the submerged ridge that are thought to have been used as hunting blinds by Paleo-Indians.
The extent of development among Eastern Woodlands Native American societies on the eve of European contact is indicated by the archaeological evidence of a town on or near Lake Huron that contained more than one hundred large structures housing a total population of between 4,000 and 6,000. The French, the first European visitors to the region referred to Lake Huron as La Mer Douce, "the fresh-water sea". In 1656, a map by French cartographer Nicolas Sanson
The rock bass known as the rock perch, goggle-eye, red eye, is a fresh water fish native to east-central North America. This red eyed creature is a species of freshwater fish in the sunfish family of order Perciformes and can be distinguished from other similar species by the six spines in the anal fin. Rock bass are native to the St Lawrence River and Great Lakes system, the upper and middle Mississippi River basin in North America from Québec to Saskatchewan in the north down to Missouri and Arkansas, south to the Savannah River, throughout the eastern U. S. from New York through Kentucky and Tennessee to the northern portions of Alabama and Georgia and Florida in the south. The rock bass has been found in the Nueces River system in Texas They are similar in appearance to smallmouth bass, but are quite a bit smaller. Identifying characteristics of rock bass are their two dorsal fins that have spinous and soft-rayed united portions, a large mouth, six anal spines, red eyes; the mouth of a rock bass is located in the terminal position, below the snout, with small conical teeth to eat prey.
The average rock bass is between 6 and 10 in, they weigh over a pound. Few rock bass live beyond 10 to 12 years. A. rupestris, the largest and most common of the Ambloplites species, has reached a maximum recorded length of 43 cm, a maximum recorded weight of 1.4 kg. It can live as long as 10 years; these fish have body coloring from golden brown to olive with a white to silver colored belly and have the ability to change their color to match their surroundings. This chameleon-like trait allows them to thrive throughout their wide range. Rock bass prefer clear and vegetated stream pools and lake margins. Rocky banks of northeastern lakes and reservoirs are a common habitat for rock bass, their favorite habitat cool to warm waters. Rock bass species are found near rocky shorelines, they can be unflustered by the presence of human activity, living under lakeside docks and near swimming areas. Rock bass are seen in groups near other sunfish. Large bass, northern pike and walleye prey on young rock bass.
Rock bass compete with smallmouth bass for food. It is carnivorous, its diet consists of smaller fish, including their own young at times, yellow perch, minnows, as well as insects, crustaceans. Rock bass are known to take food from the surface. Adult Rock bass may eat particularly in the evening and early in the morning. Rock bass are surviving in their environments and are listed as a species of "least concern" on the IUCN red list. Based on their population stability, rock bass do not require any special monitoring or conservation management plans; as a sport fish, Rock bass are managed to some extent by regulations. There are slot limits for rock bass on some bodies of water. Nursery/artificial ponds are types of management to maintain Rock bass populations. Rock bass are sexually mature at about 2 to 3 years of age. Rock bass are polygynandrous, in which both females and males have multiple mates during the breeding season. Spawning occurs from April to early June in warm waters ranging from 12 to 15 degrees Celsius, with females laying from 2,000 to 11,000 eggs.
Like other members of the sunfish family, the male will dig a nest near the lake shallows, will aggressively guard it. A spawning area may be used, with several other rock bass nests close together; as a result, males can become quite aggressive as they attempt to defend territory and attract and hold females. Rock bass lack courtship displays, so the female enters the nest and joins the male in his circular behavior. Both the female and male release their sperm and eggs into the nest; the male guards and fans the eggs, raises the young for a short time. Rock bass are known to grow quickly. Ambloplites constellatus, a species of rock bass from the Ozark upland of Arkansas, Ambloplites ariommus are true rock bass, but regarded as separate species. Ambloplites rupestris is sometimes called the redeye or redeye bass in Canada, but this name refers more properly to Micropterus coosae, a distinct species of centrarchid native to parts of the American South. Rafinesque assigned the rock bass to Bodianus, a genus of marine wrasses.
