Disposal of Fish Carcasses After Cleaning?

Mine go in the compost, covered in used coffee grounds. Great garden fertilizer.

Yes, I realize this may not be a practical option for others.

Mine goes back in the lake the turtiles love them

I knew a guy that used to take his fish carcasses and string them up on a tree where he fished for crappie. the flies would come and lay eggs then a few days later he would have a baited hole with lots of maggots falling off into the water.
