Dan,
I'm sorry to hear about your pond and I hope that you've got this sorted out some. I realize this is an older post, but in case you're still looking for a solution I would recommend investing in a few
bait fish traps (examples linked there) and thinning your bluegill population that way (with traps). You can easily remove 30-50 fish per soak on a trap and this would add up pretty quickly for you if you had a few traps that you were working. Since your pond is not huge, you could do some damage really quickly with some traps.
Best of luck buddy. I do hope you have it turned around some at this point though.
