Thanks Bill - you've provided a lot of valuable information and I've just placed the order for the MSU publication of "Managing Michagan's Pond for Sportfishing".
I also better understand the rationale for the YP and SMB. I now have plenty of time to research and analyze my pond in Northern MI (lower pennisula) while sitting in the AC confines of my Phoenix, AZ house prior to October (I will be at my cabin in Northern MI for two weeks of bird hunting and pond work).
I'm itching to measure the depth of my pond and setting the minnow trap to confirm winterkill. I do have a lot of crayfish and frogs that should make a good food source for SMB when the time comes.
Thanks again for the assistance!
