What is the best fish to freeze?
Dense and firm-fleshed fish (like rockfish, cobia, or mahi) hold up well frozen. Softer fleshed fish, particularly fatty and oily ones (like bluefish or spanish mackerel) do not freeze well, and should be eaten fresh. Salmon and tuna have high amounts of fat, so they freeze okay, but they are much better fresh.
