For over 20 years I have frozen all my fish that I don't want to eat right away ,in a ziplock bag. In the winter and in the fall I catch many crappie,Ikeep them alive until I get home than place them in ziplock bags . I often can only put 8-10 fish in a 1gal bag.I freeze them alive . When I want to eat fish I thaw then in a sink of cool weater than claen them. They taste like I just caught them. I have never kept them longer than six months. But even at six months they taste fresh .[Dose not work for catfish]
