Raccoon Hunting In My Koi Pond, Help Needed!

[PumpkinPal]

I hope this is the proper place to post.

I have a good sized koi pond in the back yard. A few months ago, after
the koi had laid her eggs, I noticed the koi disappearing. Within 3 days, all
the adults and one junior were gone. None of the eggs hatched to survive.

I didn't know what happened until last night. I heard the neighbors dog
barking. I saw a large raccoon. I chased it, it returned about an hour ago.
Went right into the pond and had a swim.

I have 6 junior koi, a frog, and my beloved red slider turtle Honu. What can
I do? I do not wish to trap or harm the raccoon, I would just like it to go
elsewhere. I cannot net the pond, as Honu needs to come out during
the day to bask.

I've heard of things like Shake Away that are supposed to safely deter them.

Any help would be appreciated. I don't want to lose any more of my
aquatic friends.
