According to a post-author at Trader Joe's Frozen Fish (Chains - Chowhound) ',:
... if you are thawing frozen fish from a plastic vacuum pak, remove the product before thawing.
Run the package under cold water for just a minute to just thaw the plastic and slit it to remove the product. Place the product on a paper towel or prachment on a plate and thaw in the refrigerator. I can't explain it but you will not experience the fishy, "I am frozen" smell or taste if you do. I find TJ's fish (salmon, Mahi, and Ahi) pretty good. I do stay away from the ones frozen in sauce.
