Yes, definitely a raccoon. They are cherry pit conveyor belts. Full cherries go in one end, pits and whatever come out the other wherever they go. A lot like mice, but on a larger scale.

I think the fish were piping after their introduction making them easy prey. It sucks as they were $10 a piece, and it is totally my fault as I was in a hurry and had no real refuge for them yet in the pond. I am currently making stone "houses" for the fish here an there, and am now planning a PVC cage across the bottom using netting to allow fish through, but to block turtles on the lilies, and raccoons and mink on the fish.

I do have a air stone within a PVC makeshift under-gravel filter I fabricated to keep the muck accumulation to a minimum. Pulls water down through a gravel bed and up through the PVC tube via air lift.

See attachment for current progress.
