DNR - Michigan's Fish Production Program -- Summary for 2003-2004

The Department of Natural Resources, Fisheries Division reared a total of 9 different species of fish and 1 hybrid in Production Year 2006-2007. A total of 18 different strains (genetically unique types of a species) of these 10 species/types of fish were raised by our 6 hatcheries and 20 outlying rearing ponds. The total 2006-2007 fish production, as detailed in Table 1 below, was 8,946,287 fish. This number is significantly reduced from previous years because Fisheries Division placed a moratorium on walleye, northern pike and muskellunge production because of Viral Hemorrhagic Septicemia virus (VHSv) concerns. No walleye or northern pike were produced in calendar year 2007 and the totals for those fish are from late 2006. Additionally, Fisheries Division obtained 33,772 yearling Skamania (summer-run) steelhead from Indiana Department of Natural Resources. The production year runs from October 1 to September 30 and follows our budgetary year.
