I agree with the freezing method, they are cold blooded... just make sure it is their water they are being frozen in...as for people freezing and feeling pain, impossible, it is when you 'thaw' the pain sets in.
One of the worst events ever in my life was watching our fishing guide club a sailfin marlin in Mexico, I am still sick to my stomach after 10 years, it was horrifying. Nats, use the freezer method, I have had a clear conscience for over 30 years doing that, they are cold blooded, they cannot 'feel' cold, their bodies react to it by slowing down their metabolism.... and eventually falling asleep, so to speak.
