Trapped raccoons can be extremley nasty. And they are surprisingly much larger than most people imagine when you're up close and personal with one thats in a live cage trap. We had our koi pond decimated by a single raccoon over a the span of a few nights. Instead of dealing with all the hassle of trapping and relocating it, we decided to go with a deterrent. Also we read that many raccoons are actually killed by other raccoons when relocated since they are so territorial. What ended up working for us was using a gator decoy: https://www.gardenandpatiohomeguide.com/the-complete-alligator-decoy-guide/
We put it in the pond and with the movement of the water from the pump it makes it looks like its moving around on its own. We got one with eyes that light up and "glow," so that the racoons would be sure to see it at night. No more missing or half-eaten fish since. We got the idea from a family friend who had used a fake gator to stop coons from actually using his pool as a toilet.
