Pure strain BG are very hard to find in MI since the MSU Extension Sport Fishing Mgmt Bulletin states: ""BEWARE" of this combination (BG-LMB). It is a favorite in the south where it can work, but it is oversold in the North. Bass are supposed to control BG by predation, but it does not work that way in our climate. The BG overpopulate the pond and then both LMB and BG have stunted growth. IF you want LMB&BG anyway give the LMB 1-2 yrs head start in growth and spawning. Then they may have more affect on the BG"". End quote.
The MSU Bulletin may be available 'online'. Here is a fact sheet about MI stuntd BG.
http://web1.msue.msu.edu/wildlife/E-1776.pdfI could not find the Managing Michigan Ponds for Sport Fishing for free online it costs $4.00.
MSU bulletin is more encouraging for using HBG in ponds, thus lots of the MI fish farms only sell HBG. Pure strain BG are available at a few northern Ohio fish farms and a few farms in MI, depending on where you live, you may have to do some driving of 2-4 hrs one way to get your fish. Usually at fish farms, all you have to do is show up with money and they can supply fish and hauling containers to get your fish back home. Plan a road trip for fish. Make it a family adventure, the kids will remember it for years.
IMLAY CITY Fish Farm Imlay City (810-724-2185) has a couple sizes of BG, RES, HBG, Rock bass, yellow perch, LMB, SMB. MDNR probably has on their website fish hatcheries and what they sell.
IMO the LMB-BG combination can work very well in northern states, IF, as with ALL fisheries, the pond is managed properly. Mismanagement almost always is the cause of poor quality fisheries. Good pond management is what we are all about here at Pond Boss - teaching you how to BEST manage your pond and fishery - be it in the north, east, west or south.
