I have three Humboldt squid that I need to defrost for my fourth year project. I will be doing stable isotope and DNA analysis and I am going to try testing for enzymes but since it was not kept at -80 I'm not sure if that will work. Each one weights about 15 pounds, maybe a bit more and they are about two and a half feet long (with the tentacles wrapped under them). What is the safest and fastest way to defrost them? Can I put them in a container full of cold water? About how long would it take for it to thaw? Any help would be greatly appreciated!
