Here are some tips for Seafood Lovers Prepared by the National Fisheries Institute:

  • Once purchased, refrigerate products immediately.
  • For optimal freshness, use seafood products within three days.
  • If you purchase live shellfish, (i.e. lobsters, crabs, oysters, clams, and mussels), discard any that die during storage.
  • Thaw frozen seafood in the refrigerator or under cold running water, not at room temperature. Marinate seafood in the refrigerator.
  • To cook, measure fish at its thickest part. Figure 10 minutes of cooking time per inch of thickness.
