I quit adding the water because it took up so much room in the freezer, and it doesn't seem to make any difference. I found some '06 fish the a while back, and it had one corner that had broken off, There was just a little freezer burn on the edge of 2 pieces. We cut it off, fried it up and it was great.

There is no way I would try to keep fish in a zip Lock without water though.
