I agree it's pretty discusting to see and or smell rotting fish around the lake shore.

I typically clean my fish at home and freeze the carcas like you recommended. The only problems is getting my wife to agree to let me put a bag of dead fish right next to our food and remembering to throw them out on trash day, but she sees the benefit of no smell. As long as I don't end up having fish head soup for dinner. haha.
