While the need to provide sport fishing is recognized, we must also strive to ensure that native populations survive. For a discussion of the philosophy of fish introductions see Courtenay and Robins (1989) and Ferguson (1990). In this review of fish management we will deal mainly with game or "sport" fish under the following topics: past and present management practices for both cold- and coolwater species; the history and role of fish culture; and the status of trout farming. 1 Management Practices Coldwater Fisheries Coldwater fishes are those which prefer summer water temperatures ranging from about 10°C to 18°C.
Arctic grayling also supply good fishing in the McLeod mainstem near Edson and in tributaries north and west of this center. Some of the streams that have been recognized as productive fisheries are the Edson River in upper reaches, Trout Creek, Sundance Creek, MacKenzie Creek, and the McLeod mainstem. The Pembina River drains an area from the mountains southwest of Edson to Flatbush. In colder upper reaches mountain whitefish are the most abundant game fish while Arctic grayling appear to be a declining species in some tributaries.
It is primarily known for its rainbow and brown trout and mountain whitefish fisheries. Recent construction of the Three Rivers Dam on the Oldman River upstream from Fort McLeod, however, has flooded the lower several kilometers of the Crowsnest River thereby removing one of the more productive sections of the stream. Efforts to mitigate this loss to the sport fishery are being undertaken on the river above the dam through habitat improvement structures. While the upper Oldman River is generally characterized by coldwater habitat, there is a transition zone near Fort McLeod where the river changes and provides cool water habitat.
