To bed or not to bed?

Would someone please clear this up for me. I have seen bream beds with my sonar. I have never seen crappie beds. I have read where the male make beds. But I have also read that the female attach there eggs to grass and limbs. So l tried to find a picture of crappie beds versus bream beds and all I will find was bream beds and for crappie it was fish structure. Maybe some body knows where I can find out the straight to this.

I don't think Crappie make as deep a depression as a Bluegill, and they don't always make their beds on loose bottom contents (sand, muck, mud, pea gravel) so it can be hard to distinguish where the bed is located with your sonar. I've even seen a TV angler catching them "bedding" on the fins of outboard motors of boats moored at a marina :yikes

Not all lakes have "vegetation", so Crappie (Black Crappie especially) will "make do" with what's available. I've gone down a bank that transitioned from rock ledges to shallow sand/pea gravel .... catching Black Crappie off the rocks, then White Crappie off the pea gravel (so long as there was a small piece of waterlogged "wood" lying on the gravel bottom).

Thanks! I knew I had not seen any holes dug out like the bream beds that are so easy to see with side scan sonar.
