Guys, many sources say to never freeze fish. I can find them if you really want them, but take my word. Nearly every animal has nerves/nociceptors (pain sensors) and to think that fish cant fell anything exceptn there spine is silly. It's cliche but pain really does serve a prupose...to get the F-away. Everything i have read states that severing the spinal cord is the best/most humane method due to its quickness. NEVER freeze. What happens during freezing is a long and drawn out process of flesh crystalization, starting with the blood vessels. Imagine frostbite over the whole body...i never had frostbite, but i was broken down in backcountry road and my hands were freezing...the pain was rediculous and it wasnt even frostbite.
On a side note, starvation is not the worst way to go. In humans, hunger forces the body to release endorphins that numb the body from msasive amounts of pain, i can only assume that the same would happen to fish. Not sure on the clove oil...but if your friend wants to be humane but cant sever the head you should do it. You a burly guy, i have faith in your composure.
good luck.
