Salmon and tuna have high amounts of fat, so they freeze okay, but they are much better fresh.

They found that while boiling fish does reduce the toxin—by about 18 percent, in fact—steaming the filets reduced it even more, to a rate of about 26 percent. What’s more, biotoxins also pass into the steaming water and avoid our bodies almost entirely—which is a very good thing.
