Another way of sampling at least some species of YOY is go out at night with a 1/4" dip net with extension handle duct taped on if needed. The small fish will be sleeping on the bottom. Drag the net as far out as you can reach towards shore right up to the bank.
I have actually picked up small BG in the cup of one hand while they were sleeping in a few inches of water. It is no wonder larger CC can eat a lot of forage fish. I bet they eat them after dark when a lot of fish are asleep.
