When I was a young boy my dad took me ice fishing. We would catch a bunch of yellow perch and toss them on the ice where they would freeze solid.
When we headed home we picked them up and put them in a 5 gallon bucket. After an hour drive home we got the bucket out of the back of the truck and dumped them on the basement floor by the drain to �soften up for cleaning�.
After getting out of our sub-zero clothes and having something to eat we headed downstairs for fish cleaning.
I would put a couple of those perch in the 5 gallon bucket with some water and they would un-thaw and start swimming around.
Does this answer the question?
