Smallmouth buffalo, as opposed to bigmouth buffalo, have a distinctive sucker-type mouth, oriented downward. Bigmouth Buffalo – Ictiobus cyprinellus. Colouration can vary with turbidity, being very pale and yellowish in turbid waters to quite olive–blue in very clear waters (Trautman 1981). Studies on the life history and ecology of the Bigmouth Buffalo, Ictiobus cyprinellus (Valenciennes). Fish. Commercial exploitation coupled with the changes in flow regime and prolonged periods of drought may have also negatively impacted populations in the Qu’Appelle watershed. Bigmouth Buffalo usually are found in the deeper pools of larger streams, shallow overflow ponds, lowland lakes and human–made impoundments where they usually occur in schools at midwater or near the bottom (Pfleiger 1975; Trautman 1981). vii + 40 pp. In addition, Buffalo Pound Lake and Last Mountain Lake do not have known Bigmouth Buffalo populations above them in the watershed; therefore, there is no potential for recolonization unless fish can pass upstream through the existing fishways. Natural Heritage Information Centre, Peterborough ON. Provincial RECORD Sucker on Opening Day - Very Uncut Angling - May 12, 2014 - … The eggs average 1.5 mm in diameter and become attached to the vegetation or any object they contact (Becker 1983), and hatch in about 2 weeks. Bigmouth Buffalo are physiologically adapted for life in warm, turbid, eutrophic bodies of water (Johnson 1963; see also Habitat Requirements above). 2004), and native to the Saskatchewan–Nelson River drainage of Saskatchewan and Manitoba (Johnson 1963; Lee and Shute 1980; Scott and Crossman 1998; Stewart and Watkinson 2004). In 2005, a mature individual was caught at Lundar Beach, 60 kilometres north of Delta Marsh (Nelson 2003). Ohio River (Rafinesque 1819). Rawson, D.S. Becker (1983) reports that in Wisconsin they are usually found in water more than 1.5 m in depth over substrates of mud, silt, sand, gravel, clay, and rubble. The bigmouth buffalo has an largely oblique terminal mouth; the smallmouth buffalo has a slightly oblique subterminal mouth. Coad, B.W. The Bigmouth Buffalo exhibits disjunct eastern populations in the Great Lakes basin (Figure 3; see also Population Sizes and Trends), and western populations in the Lake of the Woods and Assiniboine and Red river drainages (Figure 4). However, the meat is nutritious and excellent when smoked (Becker 1983). Staroska, V.J., and R.L. 1985), and from there, upstream into the English–Winnipeg system and/or the Assiniboine–Qu’Appelle system (Crossman and McAllister 1986). Al Dextrase, Senaior species At risk Bilogist, Ontario Ministry of Natural Rsourources, Peterborough, Ontario, K9J 8M5. Wild Species 2005: The General Status of Species in Canada. Other predaceous fishes such as Northern Pike (Esox lucius), Black Bullhead (Ameiurus melas), Burbot (Lota lota), Yellow Perch and Walleye (Sander vitreus) may be found in the same waters, but the gibbous body of Bigmouth Buffalo is hard to engulf and large adults are relatively free of predation (Scott and Crossman 1998). Turbidity as the result of the degradation of littoral habitat in reservoirs caused by fluctuating water levels may further impact Bigmouth Buffalo populations (Edwards 1983). 866 p. Cudmore, B., C.A. Johnson’s (1963) study of the biology of the species in Canada has been the basis for biological information on the species in Canada and the United States (Scott and Crossman 1998). data). Stewart and Watkinson (2004) felt Bigmouth Buffalo would be vulnerable to Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix), should either species be introduced to Canadian waters. State Univ. Vol. Bigmouth buffalo, unlike its close relatives the black and smallmouth buffalos, is a pelagic filter-feeder, using its very fine gill rakers to strain zooplankton from the water. Coker, G.A., C.B. There is limited demand for buffaloes in Canada, but they may be found in the live food fish market. In Manitoba, a status of Not At Risk has been recommended. Observed, inferred, or projected trend in number of populations. The population structure within each of these zones is unknown. Hoffman (1967) listed two (species of) trematodes, five cestodes, two nematodes, three anancephalons, one leech and two crustacean parasites of Bigmouth Buffalo in North America. 1989. However, in 1997, 304 seine hauls in Last Mountain Lake yielded only a single Bigmouth Buffalo YOY (R. Hlasny, Saskatchewan Environment, pers. Oklah. (Accessed: July 2005). data). By the year 2005, it was found farther upstream in these rivers, coastal marshes (Rondeau Bay, Point Pelee, Big Creek, Essex Co.) in the western basin of Lake Erie, and the Ausable River, tributary to Lake Huron (DFO, ROM, Mandrak, unpubl. United States Geological Survey (USGS) – Nonindigenous Aquatic Species (NAS) database, Gainesville, FL. Since then, it has been collected in the Red River, and several tributaries, between the Canada–United States border and the south basin of Lake Winnipeg, into which it flows (Goodchild 1990; Stewart and Watkinson 2004), and there is an unconfirmed report from Lake Dauphin in 2002 (Stewart and Watkinson 2004). 2004). In most areas, the maximum reported age for Bigmouth Buffalo has been less than 10 years; although the oldest previously reported Bigmouth Buffalo was 20 years, it is now known that they may live considerably longer. Houghton Mifflin Company, Boston. Alberta Wildlife Status Report No. Sci. Two specimens have been collected in the Bay of Quinte, one in 1981 and one in 2005. A commercial fishery in Saskatchewan, dating from the 1940s, ended in 1983. Acad. 1962. 1985), indicating that they had probably arrived from the Assiniboine River via the floodway. Mus. In these areas, the minimum total dissolved solids during the growing season were greater than 200 ppm and there was 25–75% vegetated cover. Despite its common name, the Bigmouth Buffalo is slightly smaller than the Smallmouth, maxing out at 65 pounds. Report to the Fish and Wildlife Branch of Saskatchewan Environment. These specimens may represent a small, established population, or were introduced as suggested by Goodchild (1990), or have dispersed eastward from populations in western Lake Ontario.

While I like a good buffalo steak, I think I'll stay away from the fish of the same name. Aquatic ecosystems and Global climate change. U.S. It is characterized by a robust, deep body (body deepest over pectoral fins) and is laterally compressed (Scott and Crossman 1998, Stewart and Watkinson 2004). Nat. It is listed as special concern on the Species at Risk in Ontario List (OMNR 2005). There is no information available on natural mortality, but given that there are no known predators of the young, and that predation and disease do not appear to be significant limiting factors, an extremely successful reproductive rate may be self–limiting. 1979. 2004. Estimated extent of occurrence (Polygon method –, Observed, inferred, or projected trend in extent of occurrence. Wild Species. Further additions and corrections to the list of fishes of the Great Lakes and tributary waters. The results of a mark–recapture study in a South Dakotan reservoir indicate that the movement of Bigmouth Buffalo may be extensive with females showing a stronger tendency to move downstream than males (Moen 1974). In drought years, or years with low spring runoff, reproduction may be limited or non–existent. The Great Lakes populations are found within the Great Lakes–Upper St. Lawrence National Freshwater Biogeographic Zone, and the Manitoba and Saskatchewan populations are found in the Saskatchewan–Nelson River National Freshwater Biogeographic Zone. University of Kansas Museum of Natural History Miscellaneous Publication 45: 1–357. Are there extreme fluctuations in number of mature individuals? In the Great Lakes basin, it was first caught in Lake Erie in 1957 (Scott 1957), and then in Lake St. Clair by 1972 (Goodchild 1990). Foods of buffalofishes, genus Ictiobus, in central Arizona reservoirs. Ed. Crossman and McAllister (1986) substantiated its presence in the Assiniboine River. Smallmouth Buffalo – Ictiobus bubalus. Rawson (1949) also indicated it as present in the North Saskatchewan River at Prince Albert; however, according to his field notes, Rawson was reluctant to do so because he had never examined the specimen (R. Hlasny, Saskatchewan Environment, pers. Assiniboia fisheries. Ron Hlasny, Ecosystem Management Section, Resource Stewardship Branch, Saskatchewan Environment, Regina, SK S4S 5W6. 2003. Nebraska Game and Parks Commission, Technical Series, Report 4, Lincoln, Nebraska. Willoughby. Ontario Ministry of Natural Resources (OMNR). The fish are capable of living up to 110 years old. Young of the year (YOY) Bigmouth Buffalo appear by the end of June in the Qu’Appelle River (Johnson 1963), and in the Red River in early to mid–July (Stewart and Watkinson 2004). 1970). J.E. comm.). Bigmouth Buffalo from Minnesota and Tennessee were consistently larger than those from Saskatchewan at each age group (Carlander 1969). Stewart, K.W., I.M. Leach. A total of 58 km of the river channel was deepened and 19 of 32 km of meanders were removed. Doubleday, Page and Co., Garden City, NY.

Bethesda MD. Galt House Publishing, Oakville ON. T. Theysmeyer, Royal Botanical Gardens, Hamilton, Ontario. 1998. The Bigmouth Buffalo is a large fish of Dua Ribu Lake, also known in the real life as the Brown Buffalo or Buffalo Fish.They are nearly indistinguishable from the Smallmouth Buffalo underwater, and can only be told after the fish is caught. However, the stockings did not differentiate by species, they were simply recorded as “buffalofish”, and it is impossible to determine which species were planted where. Hlasny (2003) also calculated that, based on a mean population estimate of 8700 fish, there would be 2865 fish, weighing 19,390 kg, within the size range of the commercial fishery. 1975. Canadian Field–Naturalist 93(2): 179–180. The missing year classes and age structure of this population indicate that overall recruitment is low, and that the population is under severe stress. Bigmouth Buffalo are not usually considered a sport fish and will seldom take a hook (Jordan and Evermann 1923). data). Evermann. Tafanelli, R., P. E. Mauck and G. Mensinger.

These alterations reduced the frequency of the channel flooding its banks and the length of time the banks are flooded thereby reducing spawning habitat and opportunity (see Limiting Factors and Threats). Wild Species. They prefer waters of low gradient and moderate to slow current, and do not penetrate waters of steep gradient. 2000. On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. It was only recently (2003, 2004) collected in the Detroit River during a boat electrofishing survey of Area of Concern sites (CMN, unpubl. Stewart et al. Bigmouth Buffalo, Ictiobus cyprinellus. v+ 43 pp. Bigmouth Buffalo are found in lakes and medium– to large–sized rivers in slower waters. In Canada, the Bigmouth Buffalo occurs in publicly owned waters, and all fish habitat within these waters is protected by the federal Fisheries Act. Buffalo and carp have long been confused or categorized together by anglers. Smallmouth Buffalo Ictiobus bubalus.

In the Great Lakes basin, disjunct populations have been reported from the Lake Erie, Huron, Ontario, and St. Clair basins. By admin Posted on January 31, 2017 …Fishing the tiny torpedo for smallmouth bass. 1923. Dramatic declines in the Qu’Appelle River basin appear to be related to changes in water management practices that have led to elimination and/or degradation of spawning habitat and subsequent reduction in reproductive potential. 30 pp. Paukert, C.P. (Species at Risk Status Reports). No nest site preparation occurs (Becker 1983). data). Groups of three or more individuals, usually two males alongside one female, would rush along the water surface and then sink to the bottom, sometimes assuming a vertical position to broadcast eggs and sperm over decaying vegetation. Revised Edition. Since 1913, fish surveys were conducted at Point Pelee by the Canadian Museum of Nature (CMN), Royal Ontario Museum (ROM), Park staff and others (H. Surette, University of Guelph, unpubl. Ontario Ministry of Natural Resources Report 1992–X. 1956. Burr. Bigmouth Buffalo are found in medium– to large–sized rivers in slower waters; frequenting oxbows and flood plain lakes, sloughs, bayous, and shallow lakes (Becker 1983). Bigmouth Buffalo was designated as Special Concern in 1989 by COSEWIC. Some southern fish (both sexes) may be sexually mature by the end of their first year, and most reach sexual maturity by the end of their second year (Becker 1983, Kleinholz 2000). 1981. Other characteristics from Trautman (1981) are: lateral lines scale of 35–43; dorsal fin ray count at 24–32; and subopercle broadest at its middle, with its posterior edge forming an even curve. The Bigmouth Buffalo is one of five species in the genus Ictiobus, and one of 18 sucker species and one of two, possibly three, Ictiobus species found in Canada. Characters. Cooper, E.L. 1983. 1978. These streams have likely always been turbid to some degree, but turbidity has likely increased as a result of the clearing of forests and use of tile drains for agricultural purposes (Taylor et al. Northern fishes with special reference to the upper Mississippi Valley. His research interests are the biodiversity, biogeography and conservation of Canadian freshwater fishes. Erling Holm, Department of Natural History, Royal Ontario Museum, Toronto, ON M5S 2C6. In the habitat suitability model for Bigmouth Buffalo populations in the United States, Edwards (1983) described ideal habitat conditions for both riverine and lacustrine populations. Reply. Observed, inferred, or projected trend in area of occupancy. NatureServe Explorer: an online encyclopedia of life. In Ohio, young–of–the–year ranged from 43 to 102 mm and 127 to 178 mm by the end of their first year (Trautman 1981). However, the species is highly prized in many areas. Mandrak and Crossman (1992) listed it as “Introduced” based on the relatively recent first record (see Distribution below). Although adults are able to tolerate high turbidity (Pfleiger 1975), eggs may be adversely affected (see Anthropogenic Factors). Lee, D.S., and J.R. Shute. In the United States, the Bigmouth Buffalo is considered nationally (N5) secure. Amblodon bulbalus Rafinesque 1819:421. Bigmouth Buffalo occupy a food niche encompassing benthic and planktonic feeding and diet probably influenced by availability of foods rather than active selection (Johnson 1963). 1999. Nicholas E. Mandrak is a Research Scientist with the Fisheries and Oceans Canada in Burlington, Ontario. Habitat. 2001. 47. data) despite a similar survey using the same methods and effort conducted in 1989 and 1990 (MacLennan 1992). Johnson (1963) noted a pronounced tendency to school during the summer, often in the upper 0.6 m of water. Adv. 1979. Females apparently do not spawn every year in Saskatchewan (Johnson 1963). 2004). 414 p. Edwards, E.A. Bigmouth Buffalo can hybridize naturally with Smallmouth Buffalo and Black Buffalo (Carlander 1969; Trautman 1981; Nelson 2003).
