freezing canned tuna. Thanks for all the tips about the price book, I've got it worked out now. I have recently discovered the joys of albacore tuna vs regular tuna in a tuna salad. I probably wouldn't notice it so much in a casserole but in a tuna salad, wow, big difference!
Same would go for mackeral, shark, tuna, etc. But fish are frozen whole accidentally, all the time, and not every fish that's ever been frozen whole has been turned over to the cat food processors. You'll probably be fine if you thaw the fish, clean it (gut, head & gills), wash it thoroughly, and cook it immediately.
