I have been watching my pond closely this spring for bluegill and bass. Last fall I lost fish to a cold October Iowa rain. I have caught a few bass this spring maybe 12 bass. My pond is 2.5 acres and I see gobs of bluegill from 1/2" to 4" in length and a few on the 6-7" range. It has been stocked for 2 yrs this Sept with the BG and 2 yrs with the Bass in June 2006. I'm worried I might not have enough preditors. Is there a rule of thumb way to tell from the shore?

Thanks, FH
