If you are catching your fish in deep water there may not be much you can do to keep them alive. Fish coming up too quickly form the deep may die unless you get them back down into the deep water quickly. You can't take a fish out of that environment and depressurize it without some adverse effects on the fish.

If you did the same thing to a scuba diver you would have to decompress him/her or they could die from the Bends.

Thanks for all the help.
