bigmouth buffalo vs smallmouth buffalo
The Bigmouth Buffalo is native to North America (Nelson et al. Lynn Bouvier, M.Sc. A commercial fishery in Saskatchewan, dating from the 1940s, ended in 1983. 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. Revised Edition. Sightings, not substantiated with a voucher, have been reported by OMNR staff in southern Lake Huron in 1983, and in Lake Huron off Southampton in 2005. Locations are thus defined as occupied sites where dispersal between such sites is rare or impossible, and a single threatening event could rapidly affect all individuals (see Limiting Factors and Threats). Some even relish the species' bony nature. Although Bigmouth Buffalo share an environment with many large predaceous fishes, there is little evidence of predation on the young. Misc. Since females mature between ages 8 to 11 years, and males at 5 to 15 years, the generation time, or average age of parents in the population, would be more in the neighbourhood of 14 to 15 years in unexploited populations. MacLennan, D. 1992. Are there extreme fluctuations in number of populations? 1930. First Canadian record of a flathead catfish. Hubert. Dams, waterfalls and upland habitat and major confluences may represent separation barriers (see NatureServe 2007). 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. data). 1983. Saunders, and K.

While I like a good buffalo steak, I think I'll stay away from the fish of the same name. The initial and provisional drafts of the report were prepared by Nicholas E. Mandrak, and Becky Cudmore of the Great Lakes Laboratory for Fisheries and Aquatic Sciences, Fisheries and Oceans Canada, Burlington, Ontario L7R 4A6. 867 pp. It has also been caught in Delta Marsh at the southern end of Lake Manitoba. Can. It probably existed in the Canadian waters of Lake Erie for some time previous to its detection in 1957. Proffitt, M.A., and R.S. 1923. Pap. In Canada, the Bigmouth Buffalo occurs in publicly owned waters, and all fish habitat within these waters is protected by the federal Fisheries Act. In Saskatchewan the young are about 18 mm long by late June and 64 mm by late August (Scott and Crossman 1998), attaining an average length of 71 mm by the end of the first summer (Johnson 1963). They are also pursued by dedicated anglers wherever they are found, and every year, more and more enterprising anglers try to outwit them with hook and line. 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). The fish are capable of living up to 110 years old. The eggs were attached to grass at the edge of the channel, no deeper than 10 cm in the water column. Can. American food and game fishes. Hlasny (2003) observed Bigmouth Buffalo spawning in Last Mountain Lake and at the Craven Dam in Saskatchewan in 1996. Many of the rivers in southern Ontario are highly turbid as a result of flowing over clay substrates and through highly agricultural lands. Williams. In fact, the species exhibits a preference for warm, highly eutrophic waters (Johnson 1963; Staroska and Applegate 1970; Stang and Hubert 1984; Goodchild 1990). In contrast to smallmouth buffalo, bigmouth buffalo do not have an arched or ridge-like back. Further to the Terms and conditions for this website, some of the photos, drawings, and graphical elements found in material produced by COSEWIC are subject to copyrights held by other organizations and by individuals. 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). Two records from the Bay of Quinte (Lake Ontario drainage) may represent an introduction related to the live food fish industry (Goodchild 1990). comm.). Atlas of North American freshwater fishes.

Également disponible en français sous le titre Évaluation et rapport de situation du COSEPAC sur le buffalo à grande bouche (Ictiobus cyprinellus), populations des Grands Lacs et du haut Saint–Laurent et populations de la rivière Saskatchewan – de la rivière Nelson, au Canada – Mise à jour. 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. There is no sexual dimorphism as regard to weight at age (Johnson 1963, Hlasny 2003). data). Houghton Mifflin Company, Boston. 8-10 . Bigmouth Buffalo can hybridize naturally with Smallmouth Buffalo and Black Buffalo (Carlander 1969, Trautman 1981, Nelson 2003). Based on the Canadian Freshwater Biogeographic Zone classification adopted by COSEWIC, the Great Lakes populations are found within the Great Lakes–Upper St. Lawrence Biogeographic Zone, and the Manitoba (including Lake of the Woods) and Saskatchewan populations are found in the Saskatchewan–Nelson River Biogeographic Zone. Spawning is apparently dependent on spring flooding to provide access to spawning areas and the introduction of floodwater is necessary to activate spawning activity (Johnson 1963). However, by the year 2000, Bigmouth Buffalo were found in several rivers (Grand, Sydenham, Thames and Welland rivers) and Hamilton Harbour (Lake Ontario). Paukert and Long (1999) felt that due to the maximum length and weight of 914 mm and 36 kg respectively, individuals older than 20 years are likely. Fish.

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. While the Smallmouth Buffalo only lives around 18 years at most, their cousin the Bigmouth Buffalo (Ictiobus cyprinellus) can live up to 112 years! Sci. Several specimens were collected in the Welland River in 1997; however, limited sampling has taken place before and after the collection of these specimens (ROM, CMN, unpubl. Great Lakes Laboratory for Fisheries and Aquatic Sciences (GLLFAS). Etymology/Derivation of Scientific Name . Is the total population severely fragmented? 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). Nelson, P. 2003. Bigmouth Buffalo from Minnesota and Tennessee were consistently larger than those from Saskatchewan at each age group (Carlander 1969). Aquat. During the early 1900s indiscriminate stocking of all three species of buffalos (Bigmouth Buffalo, Smallmouth Buffalo, and Black Buffalo) occurred in the Ohio waters of Lake Erie, North Carolina, and Massachusetts (Fuller 2008). The population structure within each of these biogeographic zones is unknown. Iowa State Conservation Commission. Assessment of the Bigmouth Buffalo population of Pasqua Lake. 2004. Alberta Sustainable Resource Development, Calgary, AB. Part of the uniquely North American sucker family, the buffalos are large, heavy-bodied native fishes. Bigmouth Buffalo are not as impacted by turbidity as other freshwater fishes. Crossman. An Index of Area of Occupancy (IAO), based on 1 x 1 and 2 X 2 km overlaid grids, was estimated to be 2,210 and 3,268 km2 respectively. Changes in the fauna of Ontario. It has not been collected in the Assiniboine River above Portage la Prairie Dam despite recent sampling by boat electrofishing (Nelson 2003). Unlike their close relatives, the Black Buffalo and Smallmouth Buffalo, the Bigmouth are filter feeders using very fine gill rakers to strain crustacean zooplankton from the water. Johnson (1963) also indicated the importance of spring flooding to provide access to spawning areas and as a trigger for spawning activity. 1983. Bigmouth Buffalo are not as impacted by turbidity as other freshwater fishes. Soc. 2007. 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. Buffalo and carp have long been confused or categorized together by anglers. Nebraska Game and Parks Commission, Technical Series, Report 4, Lincoln, Nebraska. Figure 6: Commercial Catch of Bigmouth Buffalo Taken from Pasqua Lake Between 1950 and 1983, with the Available 2000 Catch in kg Shown. 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). comm.). 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.

Papers Michigan Academy of Sciences 11: 425–436. 377 p. Hesse, L.W., C.R. All of the buffalo fish types, being bigmouth, smallmouth and black buffalo, originate from and are native to the U.S., as well as parts of Canada, Mexico and Guatemala, which are also the only regions in the world they can be found and caught. The Bigmouth Buffalo was first captured in Lake St. Clair in Mitchell’s Bay in 1972. Technical Report 83–2. Status of the Bigmouth Buffalo, Ictiobus cyprinellus, in Canada. Sci. In 2004, 30 sites in the Inner Bay were intensively sampled by boat electrofishing (> 1,000 sec/500m site) (N.E. Eddy, S., and S.C. Underhill. In Illinois, spawning was observed in a reservoir at depths of 0.5–0.75 m over a bottom of hard–packed clay and some gravel, with decomposing vegetation (Burr and Heidinger 1983). 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. Bigmouth Buffalo are found in lakes and medium– to large–sized rivers in slower waters. The black buffalo mouth is located just beneath the front end of the nose, and it is ever so (ever so) slightly oblique while the smallmouth buffalo mouth is located further back, and is nearly horizontal. Disjunct populations are also found in the Assiniboine and Red river drainages of the Hudson Bay basin. Bigmouth Buffalo from the Red and Assiniboine rivers showed no evidence of introgression, thought possibly to have occurred with smallmouth buffalo in the nearby Pembina River of North Dakota (H. Bart, Tulane University, unpubl. Bigmouth Buffalo – Ictiobus cyprinellus. 1959. 123 cm (4 ft), common to 35.6 cm (14 in) Fin Element Counts. Bigmouth Buffalo also have a particular “bouncing” feeding movement, swimming at an angle of about 55° to the bottom and “bouncing” or “skipping” along as they suck up food particles (Johnson 1963; Minkley et al. Bigmouth Buffalo were caught in Jeanettes Creek in 1980 and 2004 (186 individuals), and a tributary to Jeanettes Creek in 1989. The national general status ranking of Bigmouth Buffalo is secure (4) (CESCC 2006). Wittman, K.J. The number of eggs contained by mature females varies with size and age; Johnson (1963) estimated that there were approximately 750,000 eggs in an 8 kg, 665 mm female from Saskatchewan, whereas Harlan and Speaker (1956) estimated that a 4.5 kg, 520 mm female from Iowa contained over 400,000 eggs. Becky has co–authored five COSEWIC reports. University of Wisconsin Press. 1970. Coloration is generally lighter than that of the bigmouth buffalo; larger individuals are often a rather uniform slate-gray, without coppery or greenish reflections. roughfish identification, lifelist angling, fishing rare unusual fish species: bowfin burbot buffalo gar redhorse suckers carp. 2005 General status of species in Canada.

Her research interests involve the biodiversity of freshwater fishes, including invasive species and the protection and recovery of species at risk. At Point Pelee, most historical sampling was done by seining. There is a significant commercial fishery in the U.S. and the species contributes a major portion of the commercial catch of the Mississippi River with catches in excess of 672 kg.ha–1 not uncommon (Goodchild 1990).

Buffalo are a robust species of large-scaled suckerfish with a body structure similar to common carp. Thus, there is a base for moderate rescue effect from populations in nearby U.S. waters; however, populations in Ohio have not been ranked, while those of Pennsylvania are considered critically imperiled, and those of Michigan are vulnerable (NatureServe 2007). However, an ongoing genetic study of buffaloes revealed that even morphologically distinct Bigmouth Buffalo exhibited extensive introgression with Black and/or Smallmouth buffaloes in the Canadian Great Lakes basin (H. Bart, Tulane University, unpubl. Goodchild (1990) provided spawning information using Johnson (1963). Long. Coker, G.A., C.B. Portt and C.K. comm. However, many nearshore areas with suitable habitat in Long Point Bay have not been sampled. Rawson (1949) described Bigmouth Buffalo as present in the Qu’Appelle River, and abundant in the Qu’Appelle Lakes (Buffalo Pound, Crooked, Echo, Katepwa, Last Mountain, Mission, Pasqua and Round lakes) (Figure 5). The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) was created in 1977 as a result of a recommendation at the Federal–Provincial Wildlife Conference held in 1976. Rawson (1949) described Bigmouth Buffalo as abundant in the Qu’Appelle Lakes (Buffalo Pound, Crooked, Echo, Katepwa, Last Mountain, Mission, Pasqua and Round lakes), and as present in the North Saskatchewan River at Prince Albert. The mouth is very large, oblique and is more terminal than in any other sucker species (Trautman 1981). Pages 53–104 in C.H. Northern fishes mature later than their southern counterparts (8 to 11 yr versus 1 to 3 yr), and may not spawn every year. Proceedings of the Southwest Game and Fish Commissioners 16: 333–348. 1986. These are presented below. Press, University Park, PA. COSEWIC. The Committee meets to consider status reports on candidate species. 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). In the Great Lakes basin, disjunct populations have been reported from the Lake Erie, Huron, Ontario, and St. Clair basins. However, in 1997, 304 seine hauls in Last Mountain Lake yielded only a single Bigmouth Buffalo YOY (R. Hlasny, Saskatchewan Environment, pers. 2004). Alberta Wildlife Status Report No. Freshwater, rivers, reservoirs, lakes, prefers waters with moderate current; enters low salinity bays. Successful reproduction appears to be associated with spring waters levels, and is dependent on spring flooding to provide access to spawning areas, to activate spawning activity (Johnson 1963), and maintain shoreline vegetation (Moen 1974; Hlasny 2003). They are apparently tolerant of changes in habitat associated with turbidity and eutrophication (Johnson 1963; Stang and Hubert 1984) and easily adapt to a variety of conditions including reservoirs and ponds (Staroska and Applegate 1970; Minckley et al. 1992. Committee on the Status of Endangered Wildlife in Canada. 1991. 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. Attempts were made to obtain Aboriginal Traditional Knowledge (ATK) on the species, but to date have not resulted in any information being brought forward for this species. and R.C. 1981. Freshwater, rivers, ponds, lakes, prefers waters with less current; occasionally wanders into low salinity waters. Its subnational rank ranges from S1 to S5 throughout its distribution in the United States (see Technical Summaries for specific state ranks). Some females were found to be immature at 475 mm (1.8 kg–age 7 to 8), but most over 508 mm (2 kg–age 11) were mature. The bigmouth buffalo has an largely oblique terminal mouth; the smallmouth buffalo has a slightly oblique subterminal mouth. A Field Guide to freshwater Fishes. This increased the flow downstream of the Craven Dam from 4.13 m3sec–1 to 12.25 m3sec–1. Staroska, V.J., and R.L. The large, oblique, terminal mouth of the Bigmouth Buffalo readily separates it from the Black (I. niger) and Smallmouth (I. bubalus) buffaloes (Bailey et al. MS Rpt.

It has recently been caught in the Red River Back Bay at St. Norbert floodgates (1998), in the Seine River Diversion (2004), in the south basin of Lake Winnipeg during beam trawl surveys (2002) (Nelson 2003), and 30 specimens were collected in the Red River during electrofishing surveys in 2002 and 2003 (D. Watkinson, unpubl. 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). Generally, feeds near the bottom, using short up and down movements to swirl the water, filtering plants and animals from the bottom. Nick has co–authored 15 COSEWIC reports.

Bigmouth Buffalo also appear to be able to endure low oxygen tensions (Gould and Irvin 1962), mild salinity, and high (up to 30° C) water temperatures (Minckley et al. University of Michigan Museum of Zoology Miscellaneous Publications No. The distribution of Bigmouth Buffalo in Canada is restricted and localized. The missing year classes and age structure of this population indicate that overall recruitment is low, and that the population is under severe stress. It has been given provincial general status ranks of 1 (At Risk) in Saskatchewan, 4 (Secure) for Manitoba, and 3 (Sensitive) for Ontario (CESCC 2006). 343 p. Poff, N.

The findings indicate that Bigmouth Buffalo can attain ages greater than 20 years, and may exceed it by a considerable margin. Am. 1999. Willoughby. Lacustrine populations of Bigmouth Buffalo are found in habitats with 25–75% littoral areas and protected embayments during the summer months. Bigmouth Buffalo are not usually considered a sport fish and will seldom take a hook (Jordan and Evermann 1923). The national rank in Canada for Bigmouth Buffalo is N4 (apparently secure), and the national general status ranking of Bigmouth Buffalo has not been assessed. 192. Wldlife Technical Report 82–2: 1–16. comm.). 1967. 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). Twenty–one specimens have been caught in the Cootes Paradise Fishway at the western end of Hamilton Harbour between 1997 and 2005 (1997 (1 specimen); 1999 (2); 2000 (6); 2002 (6); 2003 (3); 2005 (3); T.
