WISCONSIN'S LAKE MICHIGAN SALMONID STOCKING SUMMARY
Prepared by Thomas Burzynski
Lake Michigan Fisheries Work Unit Milwaukee – UW WATER Institute
Department of Natural Resources
This stocking summary is based on stocking records entered by Wisconsin DNR staff into the statewide propagation database. A stocking record was generated each time hatchery fish were stocked into Lake Michigan.
There are four types of information included in this summary report. First, total numbers of trout and salmon stocked from 1963-2016 are summarized. The numbers of trout and salmon that were requested for stocking during the current year (2017) are also included. The actual numbers of each species of fish stocked this year will depend on hatchery program production. The first summary (pages 2 and 3) is intended to provide an overview of long-term trends in the stocking of each species.
The last three sets of summaries account for fish stocked during 2012-2016. The second set (pages 4 - 7) focuses on the numbers of fish stocked in each county along the Lake Michigan shoreline in 2012-2016. The third summary (pages 9 - 28) is a set of tables detailing specific stocking sites, the grid location of each stocking site, the specific number and age of fish planted at each site, and any identifying fin clips or marks. The fourth summary (pages 30 - 33) focuses on the marked trout and salmon stocked during the past five years (marked lake trout and steelhead are listed from 2005 and 2008 to the present respectively).
Detailed stocking information for 2012-2016 was provided since this year's harvest of all species, except lake trout, will be based primarily on fish stocked in those years. For example, this year's coho catch will depend largely on yearling coho stocked in 2016. The pattern for brown trout tends to be similar to coho. The catches of rainbow (steelhead) trout this year will result for the most part from yearling fish stocked from 2010-2014. Chinook catches this year depend primarily on Chinooks stocked in 2014-2016. The lake trout catch, unlike the other species, will depend strongly on fish stocked in 2009 and earlier.
A grid map of Lake Michigan (Figure 1) is included to assist you in locating stocking sites. The ages of fish at time of stocking are indicated as fingerling (F), spring fingerling (SF), yearling (Y), or adult (A). Fin clips are coded as single or multiple clips of the following fins and/or mouth parts: adipose (A), dorsal (D), right or left maxillary (RM, LM), right or left pectoral fins (RP, LP), or right or left ventral fins (RV, LV). The acronym CWT used in the summaries stands for coded wire tag, and refers to fish that have a small wire tag inserted into their snouts. All Chinook salmon stocked in the Wisconsin waters of Lake Michigan were marked with an adipose clip and a CWT as part of a lakewide effort to determine the rates of natural reproduction in Lake Michigan. A diagram of a Chinook salmon depicting fin and maxillary locations is included with the summary (Figure 2).
A strain designation code is included in the fin clip column. Strains are coded as Domestic (D), Seeforellen (S), Lake Michigan (M), Arlee (A), Chambers Creek (C) and Ganaraska (G).
2016 Stocking Overview:
Lakewide Chinook salmon stocking numbers were reduced by 50% starting in 2013 based on agreements with other management agencies on Lake Michigan. This agreement was forged to balance the number of predators with available prey. The actual number of Chinook salmon stocked in 2016 exceeded our proposed objective of 810,000 by approximately 2,300 fish. The number of brown trout stocked in 2016 exceeded our proposed objective of 836,000 by approximately 185,000 fish. This was due to all of the brown trout at the Thunder River Rearing Station being stocked out prior to that facility closing. Stocking of steelhead exceeded the production goal of 390,000 by approximately 7,000 fish. Coho salmon stocking fell short of our objective of 500,000 by approximately 42,000. Lake trout stocking by the U.S. Fish and Wildlife Service fell short of expectations by approximately 37,000 fish.
