Description

This wildlife status report looks at the pygmy whitefish, a small, slim whitefish in Alberta that has been collected in specific habitats from only two locations in the province: Upper Waterton Lake and a restricted portion of the upper Athabasca River. Recent surveys indicate that it appears to be relatively common in Upper Waterton Lake and relatively uncommon in the Athabasca River. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

This wildlife status report looks at the bull trout, a char species native to western North America, including the major drainages of the eastern slopes of Alberta. Since the early 1900s the species has declined in both distribution and abundance due to the impact of human activities, and it listed as a species of special concern in Alberta. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

This wildlife status report looks at the westslope cutthroat trout, a polytypic species of trout endemic to western North America. Populations in Alberta and British Columbia exist on the northern periphery of the species' range. Although historically a widespread species, westslope cutthroat trout has shown dramatic global declines in the number and distribution of populations due to habitat degradation, overharvesting and the introduction of nonnative species. The Alberta population of westslope cutthroat trout has a national designation of Threatened. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

Alberta Sustainable Resource Development (SRD) initiated studies in to assess the distribution and relative abundance of species at risk throughout Alberta. Within the St. Mary and Milk river drainages, three fish species have been identified that are potentially at risk including St. Mary sculpin, western silvery minnow, and the stonecat. Although not listed as species at risk, SRD was also interested in the status of the brassy minnow and sauger. The area under study in this report included the mainstem of the Milk, North Milk, and St. Mary rivers, and Lee Creek, a major tributary to the St. Mary River. The field programs were conducted during summer and fall 2000 and 2001. Overall, 16 fish species were encountered in the Milk and St. Mary drainages during the present study. Of the five species of interest, all were encountered in the Milk River. Only the St. Mary sculpin was recorded in the St. Mary River and Lee Creek.

Description

This wildlife status report looks at the shortjaw cisco, a freshwater fish with trout-like bodies with with larger scales than trout or salmon and no teeth on the bones of the jaw. It is listed as threatened in Canada and may be at risk in Alberta. The only verified report of shortjaw cisco in Alberta is from Barrow Lake in the Canadian Shield region of the province. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Distribution and relative abundance of the shortjaw cisco (Coregonus zenithicus) in Alberta

Description

Barrow Lake, located about 60 km north of Fort Chipewyan, contains the only verified population of shortjaw cisco in Alberta. A specific search for shortjaw cisco in the area around Barrow Lake was undertaken in an effort to gather additional information on its extent of occurrence in Alberta. Eight lakes in the region north of Lake Athabasca and east of Wood Buffalo National Park were surveyed by gillnetting in July and August 2000. No new populations of shortjaw cisco were found at these sites. Seven other nearby lakes had been sampled in 1996 and 1997 with similar results. Catch-per-unit-effort data from Barrow Lake suggest that this population of shortjaw cisco appears to have been stable over at least the past five years and probably the last 30 years. However, further monitoring is required to determine population trends with a scientifically acceptable level of confidence.
