I'm another one that says stay away from plastic bags. Many yrs ago the AZ g/f had a news letter. It said to stay away from plastic bags because of the taste they gave to fish. I suppose that the plastic bag chemistry has changed over the yrs but I still stay way from them on the rare times I keep a fish. If you want to freeze your fish do it in the paper milk carton filled with water, not a plastic bag. Wet newspaper and wet brown paper bag work in all but the hottest temps to get fish safely home much like the canvas water bags kept water cool yrs ago
