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. 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). 1989.

Ictiobus, Greek, meaning “bull fish;” bubalus, Greek for “buffalo” (Pflieger 1997). It lives in clearer water than the Bigmouth Buffalo and slower currents than the Black Buffalo. Willoughby. Bigmouth Buffalo can hybridize naturally with smallmouth buffalo and black buffalo (Carlander 1969; Trautman 1981; Nelson 2003), and are thought to have done so in Canadian Great Lakes waters (H. Bart, Tulane University, pers. Mandrak, N.E. The gill rakers of Bigmouth Buffalo are specialized for plankton feeding (Johnson 1963; Starostka and Applegate 1970). Maximum Size. Northern fishes mature later than their southern counterparts (8 to 11 yr versus 1 to 3 yr), and may not spawn every year. Atton, F.M. 1985), and from there, upstream into the English–Winnipeg system and/or the Assiniboine–Qu’Appelle system (Crossman and McAllister 1986). There is limited demand for buffaloes in Canada, but they may be found in the live food fish market. Its current presence in Canadian waters of the Great Lakes basin is probably a reflection of a northward range extension at some time in the past. In 2005, a mature individual was caught at Lundar Beach, 60 kilometres north of Delta Marsh (Nelson 2003). In fact, the species exhibits a preference for warm, highly eutrophic waters (Johnson 1963; Staroska and Applegate 1970; Stang and Hubert 1984; Goodchild 1990). Given the taxonomic and systematic problems, this genus is of some scientific interest. Bigmouth Buffalo have a highly adapted and size–selective filtering mechanism, and are able to feed mid–water and on the bottom (Nelson 2003; Stewart and Watkinson 2004). 2007. 1995. Fish.

On that basis, there are approximately 20 known (extant) occurrences in Canada constituting seven locations. In comparison, the mouth of the smallmouth buffalo, is smaller, almost horizontal when closed, subterminal, and protracts downward in typical sucker fashion. The smallmouth buffalo (Ictiobus bubalus, from the Greek for "bull-fish" and "buffalo") is a Catostomidae 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 (I. cyprinellus) and the black buffalo (I. niger), although the smallmouth buffalo's mouth is located ventrally like other Catostomidaespecies, while the bigmouth buf… Bigmouth Buffalo are not as impacted by turbidity as other freshwater fishes. In Canada, disjunct populations have been reported from the Lake Erie, Huron, Ontario, and St. Clair drainages of the Great Lakes basin. 1970; Nelson 2003). Field–Nat. The bigmouth buffalo is a large-bodied native fish. Hinks (1943) reported only one specimen of 12.7 kg from southern Manitoba and Scott and Crossman (1998) considered it rare to absent in the Red and Assiniboine rivers. 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).

Recent sampling included boat electrofishing (>1,000 sec/500m site) and fine–mesh hoopnetting (2 nets set overnight) around Rondeau Bay in 2002 (10 sites, electrofishing only) and 2004 (16 sites), and sampling the inner marshes of Rondeau Provincial Park by seining and fine–mesh hoopnetting in 2005 (N.E. Becky Cudmore is a Research Biologist with Fisheries and Oceans Canada in Burlington, Ontario. 10:25 . However, many nearshore areas with suitable habitat in Long Point Bay have not been sampled. However, buffalo lack the barbels of carp. 2000. The Freshwater Fishes of Manitoba. Smallmouth Buffalo Ictiobus bubalus. The current status of the Lake of the Woods population is unknown; however, regular fisheries assessments in the Ontario waters have failed to capture any additional specimens since 1976 (A. Dextrase, OMNR, pers. Their occurrence may have been the result of a failed, undocumented introduction, or the long–distance dispersal of individuals from populations in Manitoba or Minnesota. 1970). Definition of the (DD) category revised in 2006. Wittman, K.J. Buffaloes are superficially similar to the Common Carp (Cyprinus carpio) and Goldfish (Carassius auratus) but these species have stiff, serrated spines leading the dorsal and anal fins, and Common Carp also have barbels (Page and Burr 1991). The Bigmouth Buffalo has not been collected in a standardized manner, nor have there been any specific studies on population sizes, in Canada. The Bigmouth Buffalo has not been collected in the St. Clair River despite boat electrofishing surveys of ten 500 m transects along the river in 1989, 2003, 2004 and 2007 (CMN, unpubl. Collections from the Red River near East Selkirk in 1978, and Lower Devil Lake in the Lake Winnipeg drainage in 1981 (Goodchild 1990), provided further evidence of a more extensive distribution in Manitoba. 2007.

SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. Are there extreme fluctuations in area of occupancy? 2004. There are at least three locations in this Biogeographic Zone (Table 2). Coloration is generally lighter than that of the bigmouth buffalo; larger individuals are often a rather uniform slate-gray, without coppery or greenish reflections. Nat. Saskatchewan 1947, Regina SK. Rondeau Bay was sampled in 14 different years since 1921 by the CMN and ROM (Royal Ontario Museum, unpubl. Is there sufficient habitat for immigrants here? 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. The success of Bigmouth Buffalo populations, at least in the Saskatchewan–Nelson Biogeographic Zone (Johnson 1963), may be density dependent, as has been noted in cultured populations (Kleinholz 2000). The Bigmouth Buffalo is one of 18 (19 if smallmouth buffalo is present in Canada; see Mandrak and Cudmore 2005) sucker species found in Canada (Scott and Crossman 1998), and one of 15 (16) sucker species found in the Canadian Great Lakes basin (Cudmore–Vokey and Crossman 2000). 19 pp. 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. Formerly described as “Not In Any Category”, or “No Designation Required.”. The only voucher–confirmed specimens of Bigmouth Buffalo collected from the Canadian portion of the Lake Huron drainage were caught at the mouth of the Ausable River by boat electrofishing in 2003 and 2007 (CMN, unpubl. The Bigmouth Buffalo was first caught in Lake Erie in 1957, and subsequently both in the lake, and some of its wetlands and tributaries. Nelson, J.S., E.J. comm.). A large freshwater fish, the Bigmouth Buffalo can attain a maximum length and weight of 914 mm and 36 kg respectively, and individuals can attain ages in excess of 20 years (see Biology below). A diet study in Indiana found that the dominant items (over 80% in volume and frequency) in the stomachs of Bigmouth Buffalo were sand and silt particles with dead plant and animal material, algae and other microflora and microfauna (Whitaker 1974). Synopsis of the parasites of fishes of Canada. 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. The mark–recapture study estimated a population size between 8535 and 12,326 individuals using both Schnabel and Schumacher methods (Hlasny 2003). Trautman (1981) indicated that it was first recorded in the Ohio waters of Lake Erie in 1854, and Hubbs (1930) indicated it was sporadically present as well, but was not recorded again until after the 1920s.

Canadian Endangered Species Conservation Council (CESCC). Bigmouth Buffalo are not as impacted by turbidity as other freshwater fishes. They are most similar to the carpsuckers (genus Carpiodes), but are olive coloured and have a semicircular subopercle compared to the silver colour and subtriangular subopercle in the carpsuckers (Page and Burr 1991). Hlasny (2003) updated the Johnson (1963) report by providing spawning observations within the Qu’Appelle River basin, Saskatchewan, starting from early June and going to August in water temperature from 13.1–25.5°C.
