The Lac La Biche Fisheries Restoration Program was initiated in 2005 as a six-part program with management actions targeting commercial and recreational fishery reductions, walleye stocking, double-crested cormorant control, protection of critical fish areas and monitoring. The social objective of the program was to improve fishing opportunities for future generations by resotring the lake to historical conditions. The ecological objectives were to recover the walleye population and improve the overall size structure of the fish community.

Buck Lake has native fish populations of Walleye, Lake Whitefish, Northern Pike, Yellow Perch, Burbot, White Sucker, Trout-perch, Brook Stickleback, Iowa Darter and Spottail Shiner. The lake has a long history of providing an excellent summer Walleye sport fishery and a winter Lake Whitefish commercial fishery. It also supports a First Nations fishery. Over the past decade, fisheries biologists have noted a decline in the populations of both Walleye and Lake Whitefish. Furthermore, the size of Walleye being caught has decreased. These trends are a concern to the resource users who fish Buck Lake, as well as the fisheries biologists who manage it. Background Recreational fishing, ongoing summer kills and cumulative habitat loss are currently the main factors affecting fish populations in Buck Lake. Other factors, such as the harvest of Lake Whitefish through the commercial and First Nations fisheries are relatively minor. Recent surveys of recreational fisheries indicate that the...

Description

The lake sturgeon is a unique component of Alberta's wildlife and a prized sportfish. In Alberta, lake sturgeon are now confined to two areas: the North Saskatchewan and South Saskatchewan river systems. This project assessed the management utility of existing harvest data on species populations by means of a creel survey on the South Saskatchewan River conducted in the summer of 2000. The survey data were compared to data collected from an annual questionnaire sent to all holders of a sturgeon fishing licence.
