I did just what you are thinking about, but I ran a 2' long string thru the foam, tying one end to a brick to keep the foam from dancing all over the pond. Even so, I'm noticing some of them are flipped over. I don't know what's doing it, either the wind or some critter. I haven't noticed any spawning activity, but then again, I haven't noticed many FHM either....
CJ, not that I disagree with you about not stocking BG/RES first in Northern Ponds due to stunting, but can you (or anyone for that matter - ewest in particular) point me to any recent (say from year 2000 until present) studies that targeted that issue? The reason for the time frame, is that pond management seems to be going thru a rapid growth stage, and management techniques that were thought to be taboo 15-20 years ago are being turned topsy-turvy.
