That sounds like really, really good growth... certainly with enough food anything may be possible. Given the time it should take to grow just to 12", 5-8" in only one summer seems pretty surprising. If they are indeed the product of this years spawn.. then you have found yourself some darn good breeding stock my friend. : )
So where did you end up getting the bluegill? Are they pure or hybrids that you found? (This end of town we only seem to have trout available)
Getting more time out on the pond these days eh? Are they getting close to finishing gravel operations?
