The Great Lakes Fishery Commission’s fish stocking database is designed to summarize federal,
provincial, state, and tribal fish stocking events. This database contains agency provided records dating back to the 1950’s and is available online at: (http://www.glfc.org/fishstocking/). The purpose of this report is to briefly summarize the information in the GLFC database for Lake Michigan federal lake trout stocking and stocking rates of all salmonids within state waters of Lake Michigan (Table 1). A summary of lake trout stocking locations, described by priority area
in A Fisheries Management Implementation Strategy for the Rehabilitation of Lake Trout in Lake
Michigan (Dexter et al. 2011), is also included (Figure 1, Table 2). Total numbers of Service stocked lake trout are shown by statistical district for the time series 1976 – 2010 in Table 3 while salmonid stocking totals for each state are described in Tables 4-7 (Wisconsin, Illinois, Indiana, and Michigan, respectively).

2010 stocking overview: 12.3 million salmonids (combined species) were stocked in Lake Michigan in 2010, (Table 1). This number reflects slight increases in chinook salmon and lake trout stocking numbers compared to 2009. Chinook stocking has been stable since the 25% stocking reduction for Chinook salmon was enacted in 2006. As of 2007, slightly greater numbers of lake trout have been stocked relative to Chinook salmon (Figure 2).
Figure 2. Numbers of lake trout and Chinook salmon stocked in Lake Michigan, 1976 – 2010. Lake trout numbers reflect yearling and fall fingerling stages combined.
