MyFishFinder.com Just like iceshanty but warmer
I try not to let them freeze! My experience with frozen fish is when you can finally fillet them the meat is mushy. Use a bucket filled with water or I have heard of an Ice Well. http://todaystackle.com/icewell.html I heard these are pretty nice. 8)
Bret, you are right...once they freeze and thaw, they are more mushy than if you keep them from freezing. If you let them freeze, then thaw them to clean them, then freeze the fillets, and thaw them again later to eat them, you may as well be eating fish patties. I don't throw mine in water like you, but I bag them and keep them in my shanty where it is warmer so they don't freeze.
