You can also use the sink to thaw your fish; however, it should be dedicated to keeping the fish during defrosting to avoid contamination.

If you are thawing salmon that was frozen in a block of ice, run cold water over the fish until all the ice chunks are removed. Then cover the fish in plastic wrap, place it in a pan and leave it in the refrigerator for 6 to 12 hours.

Microwave defrosting is the least recommended way to defrost fish. The rapid heating of the flesh causes the fish’s cell walls to burst. The fish will likely be unevenly defrosted and dry.
