626 Sucker Family-Catostomidae Island Lake in the 1960s. It was mounted by Neal Long of Sayner and displayed at the Sportsmans Bar in Arcadia (Trempealeau County) in the 1970s. This fish probably derived from fish-rescue plantings from the Mississippi River, which were made during the 1930s. Cahn (1927) observed the smallmouth buf- falo from Lac La Belle (Waukesha County), and noted that it was more common in the Rock River. He also observed one specimen from the Fox River near Wau- kesha that weighed 5.9 kg (13 lb). The Waukesha County reports probably represent the last remnants of a disjunct population; specimens for verification of these reports are not available. H. E. Neuenschwan- der (pers. comm.) reported that the smallmouth buf- falo was taken from the Rock River between Hustis- ford and Watertown as late as 1965. The smallmouth buffalo is uncommon to common in Wisconsin; in some large waters it is the dominant buffalo species. The smallmouth buffalo is found in pools, oxbow lakes, and deeper waters of large rivers.

Occasionally young are taken from the mouths of small streams tributary to large rivers. BIOLOGY At the latitude of Wisconsin spawning occurs from April to early June at temperatures of 15.6-18.3°C (60-65°F). The presence of smallmouth buffalo in spawning condition in a small creek suggests that they sometimes ascend small streams to spawn (Coker 1930). Attempts to propagate buffaloes at the fisheries biological station of Fairport, Iowa, have been described by Coker (p. 192): * . . natural propagation. . . met with no success until the spring of 1917, when the conditions were varied by keep- ing the pond about half full of water in the early part of the season and allowing it to fill gradually early in May. A few days after the production of this artificial flood stage the splashing of buffalo fish was observed (May 11 and again May 17, 18 and 19) in overflow regions along the margins of the pond, and propagation was found to have been suc- cessful .... The rise should begin when the temperature
