Well stop and think if they can skim 1 or 2 fish per person that adds up. And easier to do one perch. I know sometime the fish are small and not worth cleaning, or maybe 1 get butchered or ate by the machine, but 13 us a lot off.

I know for sure bays edge will ask if you want the cheek meat, if no....they don't waste that for certain. I have seen the huge bags of nothing but cheek meat.
