Sturgeon Assessment on the St. Louis River
Midwest Region, July 6, 2004
Print Friendly Version
The restoration of lake sturgeon to historic areas is a high priority to the people of the Fond du Lac Band of Lake Superior Chippewa. Using set lines, gill nets and Windemere trap nets, the Ashland Fishery Resources Office is assisting the Fond du Lac Band in assessing the recruitment of these fish. This study will be conducted in 2004, 2006, and again in 2008. Several river sections within a 20 mile section of the upper St. Louis River, upstream of Cloquet, Minn., will be sampled for sturgeon. This study was conducted in 2001, but it must be repeated periodically to determine the survival and recruitment from four years of stocking (1998, 1999, 2000, and 2003). The sturgeon stocked between 1998 and 2000 should be of a size, which should make them more susceptible to capture gear.

The goal of the project is to restore and maintain a self-sustaining river resident population of the lake sturgeon by 2025, on the St. Louis River system upstream of Cloquet. The assessment study now underway is necessary to determine the success of four previous stocking efforts.

The objectives of this study are to determine the survival, recruitment, growth rate, distribution and habitat use, and determine the best capture techniques. The assessment program began in June as the first of five surveys to be conducted this summer. Although only catfish and red suckers were collected during this first assessment, the crew is optimistic that they will soon be able to locate juvenile sturgeon.
