I found this series of articles that makes for great reading on those cold, nasty days prior to the spawn. I have not read all the sections, but have found valuable information on the ones titled crappie habitat. Take a look and I would predict you can find some valuable information whether new or an old grizzly in crappie fishing.

I hope the link will work, if it does not then copy the above and put it in the computer entry subject area and enter.

It will be worth your while,

Good Fishing if you have water,
