Come on, I know there has to be at least one pond psychic in the crowd! I would love to be able to do an electroshock survey but that's not really in the budget right now and I'm pretty sure the owner doesn't have enough interest to pay for it. I will try to give the seine idea a shot once it gets warmer out, sounds like something my daughter might enjoy helping with as well. I did walk around the pond this morning after feeding the trout and saw 3 schools of what had to be 50+ 1" BG in the shallows.
