Description

The bull trout, the provincial fish of Alberta, is a native species that occurs in all of the major river basins of the province. It has been designated a Species of Special Concern because of the declines in distribution and abundance, as well as continued threats from habitat alteration and introduced competitive species. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goal of restoring and maintaining viable, self-sustaining bull trout populations throughout the majority of the species' historic range in the province, and to once again provide some measure of harvest opportunity for the species. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management...

Status of the bull trout (Salvelinus confluentus) in Alberta : update 2009

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... More ≫

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.

Selenium concentrations in the tissues of fish from the Upper McLeod and Upper Smoky River systems

The present study compared selenium in fish tissues from flowing water systems near three west-central Alberta mountain cola mines in the upper McLeod and Smoky River systems to the toxicity... More ≫

Description

The present study compared selenium in fish tissues from flowing water systems near three west-central Alberta mountain cola mines in the upper McLeod and Smoky River systems to the toxicity effects thresholds developed by Lemly (1996). Overall, data for fish tissues collected in 2000 and 2001 by Alberta Sustainable Resource Development showed that selenium concentrations in rainbow and brook trout were usually greater than toxicity effects thresholds in the exposed streams compared to reference streams, particularly in the tissues of fish collected from waters draining the Luscar and Gregg River mines. General patterns for selenium concentrations int he remaining fish species sampled (bull trout, mountain whitefish, Arctic grayling, and longnose sucker) compared to effects thresholds were not always as apparent. This was to some extent due to the potential influences of spawning migrations of mountain whitefish and bull trout among the exposed and reference sampling locations, and...
