I bought a whole 15lb. box of cod on sale at the store for $60. It was in the freezer at about zero and hard as a rock. I found out it was what is called a blister pack and I could just drop it to break apart. Anyway: Last night I forgot and left it out, I just found it this afternoon dripping and thawed but with ice flakes between the layers still. I think it stayed pretty cold in the center and have heard differing views on refreezing fish. If I dont refreeze it could I cook it then refreeze it. I have to waste $60 worth of Atlantic Cod, the box was labeled Peter Pan.
