I salt mine, they do not get so mushy when you salt and freeze them. I put my mullet in heavy salt brine( lots of salt, water & ice) for couple hours, then put 10 to 12 mullet in a small freezer container with brine solution (salt & water) then in my freezer . I pull out a container to fish with. If I find fresh mullet I use them , if not I use the salted mullet and what I don't use I put back in freezer.
