The bigmouth buffalo (Ictiobus cyprinellus) is a fish native to North America that is in decline. [2] [3] [4] [5] [6] It is the largest North American species in the Catostomidae or "sucker" family, and is one of the longest-lived and latest-maturing freshwater fishes, capable of living 127 years and reproducing infrequently. [4] [5] [3] [6] Even at a century old they show no age-related declines, but instead improvements relative to younger individuals, making this species a biological marvel. [7] [8] [9] It is commonly called the gourdhead, marblehead, redmouth buffalo, buffalofish, bernard buffalo, roundhead, or brown buffalo. [10] The bigmouth buffalo is not a carp, nor is any other fish in the sucker family. Although they share the same order, each belong to different suborders and are native to separate continents.
The bigmouth buffalo is typically a brownish olive color with dusky fins, but can vary greatly in color across individuals including melanistic, golden, and even xanthic color morphs. [11] [12] Bigmouth buffalo may also accrue unique black or orange pigmentation markings with age, [3] [12] and in some rare individuals, white-edged fins. [6] Like other catostomids it has a long dorsal fin, but unlike all other extant species it has a terminal (forward-facing) mouth reflecting its unique, pelagic feeding ecology. It is the largest of the buffalofishes and can reach a length of more than 4 ft (1.2 m) and 80 lb (36 kg) in weight. Generally it lives in lakes, or in sluggish areas of large rivers. Bigmouth buffalo populations have been in decline in the northern extent of their range since the 1970s, including Minnesota, North Dakota, and Canada. [2] [3] [4] [5] [6]
A 2019 study documented and validated their late maturity, centenarian longevity, and that several populations in northwestern Minnesota are composed mainly (85–90%) of individuals more than 80 years old, indicating recruitment failure since the 1930s. [3] This newfound life history information published in 2019 defied pre-conceived notions of the species. [3] A 2021 study from North Dakota also revealed a slow pace of life including late maturity, decadal episodic recruitment, declining population, and a relatively large group of old-growth individuals. [4] A 2022 study from Saskatchewan, Canada revealed remarkable tendencies of the bigmouth buffalo including a supercentenarian lifespan, skip-spawning related to water levels, proximate mechanisms underlying failed recruitment, extreme episodic recruitment, and late maturity [5] —all characteristics that make this species extremely vulnerable to overfishing, habitat degradation, and invasive species. Indeed, bigmouth buffalo are declining in Canada, [5] and have been in steep decline in contiguous areas of the US, temporally associated with the rise of modern wasteful bowfishing in the 21st century. [4] [13] [14] [6]
Bigmouth buffalo life history attributes, including the ability to survive several decades with no successful recruitment (i.e. episodic recruitment), are more pronounced than other long-lived freshwater fishes, including sturgeon and paddlefish. [4] [3] [6] Such long-lived species require time to successfully sustain themselves by surviving to periods in which favorable environmental and biotic conditions arise for booms in reproduction and subsequent recruitment through the predation gauntlet. [15] [6] [16] [17] Unregulated, unmanaged and wasteful lethal fisheries are not compatible with their biology, yet such fisheries have come to exist in the 21st century in the United States and the species is declining. [3] [4] [14] [6] [13] Canada on the other hand, has long-enforced protections for bigmouth buffalo. [5] Exemplifying the lack of management in the United States, as of 2024 anglers with a standard fishing license in Minnesota can take bigmouth buffalo in unlimited numbers statewide, including from within a National Wildlife Refuge system of the United States Fish and Wildlife Service. For example, a 2024 study [6] set in eastern Minnesota analyzed the exploited population of bigmouth buffalo and their spawning migration at Rice Lake National Wildlife Refuge across several years. Although the population of bigmouth buffalo migrates and spawns annually, truly successful reproduction has not occurred since the late 1950s. [6] With a median age of 79 years as of 2024, and greater than 99.7% of individuals hatched before 1972, these bigmouth buffalo at Rice Lake National Wildlife Refuge comprise one of the oldest known populations of animal on earth. [6]
The bigmouth buffalo's native distribution is confined to the countries of Canada and the United States of America. [18] It is native to the Red River of the North and Mississippi River drainage basins, from Manitoba, Canada, and North Dakota, United States, to the Ohio River and south in the Mississippi River system to Texas and Alabama. In Canada, they inhabit the Milk River which flows through Alberta, and the Qu'Appelle River which flows through Saskatchewan and Manitoba into Lake Winnipeg. Beginning in the northern United States, they are native to Montana, North Dakota, Minnesota, Wisconsin, and down to southern states including eastern Texas, Oklahoma and Louisiana. The major systems where they are found include the Hudson Bay and Mississippi River drainages. The introduction of bigmouth buffalo has largely been done for commercial purposes. Regions of reintroductions include some reservoirs along the Missouri River drainage of North Dakota and Montana. Regions of introduction include some reservoirs in Arizona, [12] and within California, they have also been introduced to the aqueduct system of Los Angeles. [19]
Native to North America, bigmouth buffalo are integral to ecosystems therein. [6] Bigmouth buffalo young are prey for several predatory fish, including walleye, [23] northern pike, [24] catfish, [25] [26] alligator gar, [27] [28] etc. Bigmouth buffalo filter-feed on invasive zebra mussels during the mollusk's larval (veliger) planktonic stage. [29] [30] They form the native counterpart to the invasive bighead and silver carp, and they compete with the invasive common carp. [5] However, these invasive species are outcompeting native bigmouth buffalo. [5] [3] [26] [30] Native Americans utilized bigmouth buffalo, Lewis and Clark harvested them on their journey in 1804, and the inland commercial fishing industry has valued them as a prized catch since the 1800s. [3] The bigmouth buffalo is a popular foodfish throughout parts of the United States, and has been introduced into a few southwestern states. Commercial harvesters have to obtain annual permits to net from designated waterbodies, which are rotated among on a year-by-year basis, and they must report harvest from each haul to their respective state agency. Bigmouth buffalo are then trucked in oxygenated water tanks to markets where they are sold alive. [20] They are commonly consumed in Arkansas as buffalo ribs. [31] Though it has small bones suspended in its muscle tissue like northern pike, its good flavor makes it one of the most valuable of the traditional, non-game freshwater fish. In addition to being a foodfish, the bigmouth buffalo has recently become a sportfish as catch-and-release anglers have learned to pursue them on rod-and-line, [12] [32] [33] and as lethal bowfishing has also increased in the 21st century. [4] [3] [13] [34] [14] [6] Although commercial harvest is regulated, sport-kill bowfishing is not. [4] [3] [13] [34] [14] [6]
The bigmouth buffalo is part of a unique ecology in shallow-water systems. The larval bigmouths are pelagic and sometimes benthic feeders, mostly of copepods and cladocerans, but also phytoplankton and chironomids. [18] [35] Bigmouth buffalo, unlike its close relatives the black and smallmouth buffalos, is a filter-feeder, using its very fine gill rakers to strain plankton from the water. It sometimes feeds near the bottom, using short up-and down movements to filter from the water the plankton that hover near the bottom or rest lightly on it. [36] The juveniles and adults are mostly limnetic plankton feeders that also eat cladocerans, copepods, algae, chironomids, ostracods, and other insect larvae and invertebrates depending on availability. [37] [38] The optimum habitat for spawning bigmouth buffalo is freshly-flooded vegetated waters. [5] [6] They are a very resilient fish that can tolerate high turbidity and low oxygen levels. They can be found in waters with turbidity levels over 100 ppm. A minimum total dissolved solids is 200 ppm during the growing season. During spring and summer, 50–75% pools should be present, with backwaters, and marsh areas and 25-75% littoral area and protected embayments during summer for the habitat to be suitable. [19] Bigmouth can be found in waters from 22.5 to 38.0 °C (72.5 to 100.4 °F). The optimal temperatures for incubation and hatching of eggs are from 15–18 °C (59–64 °F), but they can develop in temperatures reaching up to 26.7 °C (80.1 °F). [19] The bigmouth buffalo prefers slow-moving water that does not reach a velocity over 30 cm/s.
The bigmouth buffalo are group spawners [5] which produce 250,000 eggs/kg of adult weight; their eggs are very small at about 1.5 mm in diameter. [40] [18] The bigmouth buffalo is a spring spawner generally spawning between April and June [6] when the water temperature is between 13 and 26 °C (55 and 79 °F), but may skip spawning if water-level fluctuations are not adequate. [3] [5] The bigmouth buffalo is a broadcaster that has adhesive eggs, which it lays in vegetated waters. [5] [6] Females seek submergent and emergent vegetation, the ideal habitat for the hatching of their eggs. Water levels substantially rise before spawning, [4] [5] and the spawning timing and duration can vary significantly across years, even in successive years. [6] For example, at Rice Lake National Wildlife Refuge, Aitkin County, Minnesota, the spawning duration was 7 times longer in 2022 compared to 2021 or 2023, and the spawning timing also varied by more than 16 days comparing 2022 to 2021. Bigmouth buffalo are extremely vulnerable to exploitation during their spawning period, and will likely require protections much like is afforded to lake sturgeon or paddlefish. [6]
Salinity can be a problem for reproduction. Spawning can occur from 1.4 to 2.0 ppt of salinity which eggs and yearlings not being able to survive a salinity of over 9 ppt. [41] The minimum dissolved oxygen during the spring and summer is 5 mg/L. [19]
Recruitment success is related to water-level and drought conditions, [4] [6] the water-level recession rate after the spring peak, [5] and predation. [6] While numerous invertebrates, blue gill, yellow perch, and other species prey on the bigmouth buffalo eggs and larvae, northern pike and other piscivorous fish likely further top-down restrict the survival bigmouth buffalo fry and fingerling fish in many systems. [6] [3] [5] [12] [4] More than one male will assist in spawning by moving the female to the top of the water to help mix eggs and milt. [5] [42]
Reaching a recorded maximum of 127 years of age, the bigmouth buffalo is the longest living freshwater teleost (a group of more than 12,000 species) by more than 50 years, shattering all previous records for this group. [5] [3] [21] [43] With a previous maximum longevity estimate (prior to 2019) for this species at 26 years, [44] evidence of its extended longevity came as a surprise and was initially met with skepticism. [45] Thorough bomb radiocarbon dating was conducted on their otolith microstructure and confirmed the age estimates generated from thin-sectioned otoliths, making bigmouth buffalo the oldest age-validated freshwater fish in the world. [3] [22]
The onset of sexual maturity of bigmouth buffalo varies with latitude. In central North Dakota and southern Minnesota, females reach the onset of sexual maturation around 10 years old, while males begin maturation around 6 years of age. [4] [3] In Canada, bigmouth buffalo females had not yet reached the onset of sexual maturity by an age of 11 years. [5] Their delayed maturity (in addition to their great longevity and episodic recruitment) is a trait indicative of their slow, marathon-like, life history pace. [3] [5] [12] [4] Bigmouth buffalo have a tendency to accumulate unique pigmentation (orange and black spots) as they age, [3] [22] [12] [6] which may vary by habitat variables such as water quality and available food.
According to the Committee on the Status of Endangered Wildlife in Canada, the conservation status in the Canadian range of the bigmouth buffalo is difficult to assess due to lack of study of this animal, and the species is of special concern under the Species at Risk Act. [46] [5] Known threats include loss of backwater spawning areas due to channelization and loss of spawn viability due to high turbidity related to variation in flow rate. [46] The bigmouth buffalo is also negatively affected by dams that restrict their movement and ability to find suitable spawning habitat, they are prone to winterkill, and they are highly vulnerable to overfishing. [4] [5] [3] [13] [34] [6] The bigmouth buffalo is an endangered fish species in Pennsylvania. [47] Besides this state, the bigmouth buffalo is not currently listed as threatened or endangered in any other region of its native distribution, although the Saskatchewan - Nelson River populations designatable unit has been listed under Schedule 1 of the Species at Risk Act as being of special concern since 2011 due to contiguous declines [5] [3] [46] that have also been evident in the northern extent of their US range since the 1970s. [2] Several longstanding MN populations of bigmouth buffalo are composed almost totally (85–90%) of individuals hatched before 1940, [3] and in other systems more than 99% of individuals are from hatch-years that pre-date 1970. [6] A reflection of outdated fisheries management, harvest limits on bigmouth buffalo do not exist in these same areas - this despite the rapidly growing new sport of modernized night bowfishing that exploits this species. [4] [13] [34] The rise of bowfishing was found to be coincident with steep declines in bigmouth buffalo. [4]
The fingerlings of bigmouth buffalo are susceptible to a parasite, Lernea cyprinacae , but most are unaffected by the time they reach a length of 30 mm. [40] They are anchor parasites that attach themselves between scale margins and fin insertions. The real problem is a secondary infection that may arise due to these parasites, especially in poor water conditions. The protozoan Epistylis and bacteria Flavobacterium columnare are both related to serious parasite infestations. [40] The bigmouth has been seen to hybridize in the wild with smallmouth buffalo, and it is possible that some fish identified as black buffalo are indeed these hybrids. [48] The hybridization does not seem to be negatively affecting their populations but makes it difficult to determine how many hybrids and how many black buffalo are actually in certain reservoirs. The fish is vulnerable in shallow water and is often captured by bow and arrow via bowfishing. [13] [34] [6] [3] It is commercially caught on trotlines, setlines, hoop and trammel nets, and seines. There are currently no specific management plans in place for the bigmouth buffalo in the United States. [4] [3] [13] [34] [49] [6] In some places like the southern US, progeny have been reared in hatcheries. [40]
Management of bigmouth buffalo is in need of attention, especially in the northern part of their US range where populations are old-growth and declining. [4] [2] [6] [3] Overall, the International Union for Conservation of Nature did not consider bigmouth buffalo to be at risk of extinction in its 2013 assessment, [1] which came before recent developments in the understanding of the life history of Ictobius cyprinellus. [43] [3] [4] [5] [6] [7] [12]
On June 21, 2013, Noah LaBarge (12 years old) [50] caught the Wisconsin state record bigmouth buffalo fish. [51] It measured 49.5 inches (126 cm) and weighed 76.5 pounds (34.7 kg). [51] It was caught on 8-lb-test line [50] on the Wisconsin River at Devil's Elbow,[ citation needed ] which is on the north end of the Petenwell Flowage. It was officially recognized to be the new world record by the National Fresh Water Fishing Hall of Fame as both 8-lb-line class and all tackle.[ citation needed ]
At Mt. Juliet, Tennessee, Jeff Wilkins caught a record 62-pound (28 kg) bigmouth buffalo while fishing on Percy Priest Lake. The fish, caught in the Seven Points area of the lake on March 31, 2010, was 45 inches (110 cm) in length. According to the Tennessee Wildlife Resources Agency, it took 35 minutes for Wilkins to reel in the fish. [52] The catch beat the previous record of 52 pounds 2 ounces (23.6 kg), caught by Greg Megibben in 2001, also at Percy Priest. After the record was certified, Wilkins released the fish back into the lake. [52]
In Omaha, Nebraska, Joe Slavic caught a 64-pound (29 kg) bigmouth buffalo using mulberry bait on June 8, 2000 in a Dodge County sand pit. [53]
The International Game Fish Association all-tackle record stands at 31.89 kilograms (70.3 lb), caught on April 21, 1980 by Delbert Sisk in Bastrop, Louisiana. [54]
The quillback, also known as the quillback sucker, is a type of freshwater fish of the sucker family widely distributed throughout North America. It is deeper-bodied than most suckers, leading to a fuller-bodied appearance. However, the quillback is not a carp. Quillback are catostomids, and like all catstomids, they do not have barbels around the mouth. The quillback is long-lived, with age up to 30 years, 44 years, 49 years, and 52 years documented across different studies throughout North America.
Lake Winnipeg is a very large, relatively shallow 24,514-square-kilometre (9,465 sq mi) lake in North America, in the province of Manitoba, Canada. Its southern end is about 55 kilometres (34 mi) north of the city of Winnipeg. Lake Winnipeg is Canada's sixth-largest freshwater lake and the third-largest freshwater lake contained entirely within Canada, but it is relatively shallow excluding a narrow 36 m (118 ft) deep channel between the northern and southern basins. It is the eleventh-largest freshwater lake on Earth. The lake's east side has pristine boreal forests and rivers that were in 2018 inscribed as Pimachiowin Aki, a UNESCO World Heritage Site. The lake is 416 km (258 mi) from north to south, with remote sandy beaches, large limestone cliffs, and many bat caves in some areas. Manitoba Hydro uses the lake as one of the largest reservoirs in the world. There are many islands, most of them undeveloped.
The burbot, also known as bubbot, mariah, loche, cusk, freshwater cod, freshwater ling, freshwater cusk, the lawyer, coney-fish, lingcod, or eelpout, is a species of coldwater ray-finned fish native to the subarctic regions of the Northern hemisphere. It is the only member of the genus Lota, and is the only freshwater species of the order Gadiformes. The species is closely related to marine fish such as the common ling and cusk, all of which belong to the family Lotidae (rocklings).
Bowfishing is a fishing technique that uses specialized archery equipment to impale and retrieve fish. A bowfisher will use a bow or crossbow to shoot fish through the water surface with a barbed arrow tethered to a line, and then manually retrieve the line and arrow back, in modern times usually with a reel mounted on the bow. Unlike other popular forms of fishing where baiting and exploiting the fish's instinctual behaviors are important, bowfishing is similar to spearfishing and relies purely on the fisherman's own visual perception and marksmanship, and usually do not involve using other tools such as hand net.
The freshwater drum, Aplodinotus grunniens, is a fish endemic to North and Central America. It is the only species in the genus Aplodinotus, and is a member of the family Sciaenidae. It is the only North American member of the group that inhabits freshwater for its entire life. Its generic name, Aplodinotus, comes from Greek meaning "single back", and the specific epithet, grunniens, comes from a Latin word meaning "grunting". It is given to it because of the grunting noise that mature males make. This noise comes from a special set of muscles within the body cavity that vibrate against the swim bladder. The purpose of the grunting is unknown, but due to it being present in only mature males and during the spawning season, it is assumed to be linked to spawning.
The bighead carp is a species of cyprinid freshwater fish native to East Asia, and is one of several Asian carps introduced into North America. It is one of the most intensively exploited fishes in fish farming, with an annual worldwide production of over three million tonnes in 2013, principally from China. Unlike the omnivorous common carp, bighead carp are primarily filter-feeding algae eaters, preferentially consuming zooplankton but also phytoplankton and detritus.
The silver carp or silverfin is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia, from the Amur River drainage in the north to the Xi Jiang River drainage in the south. Although a threatened species in its natural habitat, it has long been cultivated in China as one of the "Four Famous Domestic Fish" (四大家鱼) together with Bighead carp, Black carp and Grass carp. By weight, more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species.
The black buffalo is a North American species of freshwater fish in the Catostomidae or sucker family. With a lifespan of up to 108 years, it is among the longest-lived of freshwater fish species. Found in the Mississippi Basin and southern Great Lakes. It was first discovered in Canada in the western end of Lake Erie and has been reported from Boston Creek. The Tennessee distribution ranges from rivers and streams in the Cumberland Mountains, a few rivers in middle Tennessee, and in west Tennessee along the Mississippi River. The ecology of the species is quite similar to that of I. bubalus. I. niger has a ventrally positioned mouth, making the species’ diet benthic-oriented. It has a distinct shape that mocks I. bubalus and I. cyprinellus, considering it a hybrid between the two species.
The golden redhorse is a species of freshwater fish endemic to Ontario and Manitoba in Canada and the Midwestern, southern, and eastern United States. It lives in calm, often silty or sandy waters in streams, small to large rivers, and lakes.
The greater redhorse is a species of freshwater fish found in northeastern North America. It is the largest member of the genus Moxostoma, with a maximum length of 80 cm (31.5 in). The greater redhorse is long lived with a maximum reported age of 27 years.
The shorthead redhorse is a wide-ranging species in North America. The shorthead redhorse is native to central and eastern North America. However, its range has expanded to include areas like the Hudson estuary and Grayson County, Texas. It inhabits small to large rivers and lakes, and lives in the benthic zone. Shorthead redhorse feed on benthic invertebrates and can consume plant material from the benthic environment that it inhabits. When it spawns, shorthead redhorse move into more shallow streams and spawn over gravel or rocky shoals. They will also spawn in springs with swift moving water. The shorthead redhorse is important to humans because it is a game fish. It is also important to anglers because of its role in the ecosystem; it is prey for larger game fish such as northern pike and muskellunge.
The silver redhorse is a species of freshwater fish endemic to Canada and the United States. It is the longest-lived redhorse known, with a maximum reported age of 41 years. Sometimes called redhorse or sucker for short, it is in the family Catostomidae with other suckers. The species is distributed from Quebec to Alberta and is also in the Mississippi River, St. Lawrence River, Ohio River, and the Great Lakes basins. The current world record is 6.75 kilograms, caught by Chris Stephenson on Pickwick Lake in Alabama, April 1995 and certified by National Freshwater Fishing Hall of Fame. This species is of growing interest to rod-and-line anglers. The long-lived and late-maturing silver redhorse is also a sportfish pursued by kill-and-dump bowfishing, a 21st century unregulated sport that produces tons of wanton waste, and thus management and conservation are in need of updating.
Freshwater fish are fish species that spend some or all of their lives in bodies of fresh water such as rivers, lakes and inland wetlands, where the salinity is less than 1.05%. These environments differ from marine habitats in many ways, especially the difference in levels of osmolarity. To survive in fresh water, fish need a range of physiological adaptations.
Rough fish is a term used by some United States state agencies and anglers to describe fish that are less desirable to sport anglers within a defined region. The term usually refers to larger game fish species that are not commonly eaten, are too rare to be commonly encountered, or are not favorably sought by anglers for sporting purposes. Many of these species are actually very important in the commercial fishing industry, where they make up the bulk of commercial food fish catches in inland freshwater bodies.
Moxostoma, the redhorses or jumprocks, is a genus of North American ray-finned fish in the family Catostomidae. Redhorses are variable in size, geographic location, and other ecological traits such as spawning substrate. Several redhorses are long-lived, much like many other catostomid species. The silver redhorse is the longest-lived redhorse known by nearly a decade, with ages exceeding 40 years. Redhorses are broadly of conservation concern, as these long-lived species are highly intolerant to environmental pollution, habitat fragmentation, and are currently subject to unregulated 21st century sport bowfishing which is removing and wantonly wasting several of these species by the ton.
The Catostomidae are the suckers of the order Cypriniformes, with about 78 species in this family of freshwater fishes. The Catostomidae are almost exclusively native to North America. The only exceptions are Catostomus catostomus, found in both North America and Russia, and Myxocyprinus asiaticus found only in China. In the Ozarks they are a common food fish and a festival is held each year to celebrate them. The bigmouth buffalo, Ictiobus cyprinellus, can reach an age up to 127 years, making it the oldest known freshwater teleost by more than 50 years.
Rice Lake National Wildlife Refuge is located in Aitkin County in east central Minnesota, five miles south of the community of McGregor. It was established in 1935 for waterfowl habitat preservation. The refuge includes Rice Lake itself, a shallow, 3,600-acre wild rice-producing lake. The refuge has been designated as a Globally Important Bird Area by the American Bird Conservancy due to the importance of the lake and its wild rice as a food source to migrating waterfowl, especially ring-necked ducks. Rice Lake National Wildlife Refuge has also recently become known for its population of native bigmouth buffalo that migrate to Rice Lake each spring during their annual spawning migration. With an average age of about 80 years for the bigmouth buffalo in this population and approximately 100% of individuals older than 53 years as of 2024, it is one of the oldest known populations of animal in the world.
Ictiobus, also known as buffalofishes, buffalofish or simply buffalo, is a genus of freshwater fish native to North America, specifically the United States, Canada, Mexico, and Guatemala. They are the largest and longest-lived of the North American suckers, reaching up to 1.23 m (4.0 ft) in length and more than 100 years of age for three of the five species. At up to 127 years for bigmouth buffalo, they are the longest-lived freshwater teleost, which is a group of more than 12,000 species. Bigmouth buffalo, black buffalo and smallmouth buffalo are found in the United States or Canada. Little is known about the two other buffalofish species: the fleshylip buffalo found in Mexico, or the usumacinta buffalo found in Mexico and Guatemala. Buffalofish are not carp, nor is any other catostomid; they belong to different scientific families having evolved on separate continents. Buffalofish live in most types of freshwater bodies where panfish are found, such as ponds, creeks, rivers, and lakes. Ictiobus were caught by the Lewis and Clark Expedition.
The river carpsucker is a freshwater fish belonging to the Catostomidae that is native to the inland United States and northern Mexico. This species has a slightly arched back and is somewhat stout and compressed. While the fins are usually opaque, in older fish they may be dark yellow. It is distributed along the Mississippi River basin from Pennsylvania to Montana. The river carpsucker, like most suckers, is a bottom feeder and obtains its nutrients from algae, microcrustaceans, and other various tiny planktonic plants and animals found in silty substrates. Like its congener, the quillback, the river carpsucker is long-lived, with a known maximum lifespan of 40 years in Colorado, and 47 years in Minnesota. It begins to reproduce typically in late spring, and the female usually releases more than 100,000 eggs. There is no parental care provided.
The smallmouth buffalo is recently realized as one of the longest-lived fishes, capable of living more than a century. The smallmouth buffalo is in decline across large portions of its range, and is subject to unregulated exploitation. They are a catostomid fish species native to the major tributaries and surrounding waters of the Mississippi River in the United States, as well as some other water systems where it has been introduced. It is a long-lived, stocky fish like its relatives the bigmouth buffalo and the black buffalo. The smallmouth buffalo's mouth is located ventrally like other Catostomidae species, whereas the bigmouth buffalo's mouth is terminal and opens forward. It is thought that smallmouth buffalo eyes are significantly larger than those of the black buffalo. Despite being members of different scientific suborders, these three species are sometimes conflated with common carp, but an easy and notable difference is that all catostomids lack the characteristic barbels of carp, and carp are not native to North America whereas buffalofish are. Like the other buffalofish species, the smallmouth buffalo is targeted by modern bowfishing.
