The most effective way to prevent seafood poisoning is through proper storage of fish. When fish is not stored correctly, it can promote the growth of harmful bacteria and toxins, which can lead to foodborne illnesses. Proper storage involves keeping fish at the right temperature, usually refrigerated or frozen, to inhibit bacterial growth. This is crucial because seafood spoils rapidly at temperatures above a certain threshold, and bacteria can multiply even at lower temperatures if fish is not handled appropriately.

While cooking fish thoroughly is also important as it can kill some pathogens, it does not eliminate toxins that may have formed if the fish was improperly stored prior to cooking. Eating fish based solely on its smell is not a reliable indicator of its safety, as some seafood can smell acceptable while still harboring harmful bacteria or toxins, and consuming only fish you've caught does not ensure safety unless you follow safe handling practices. Therefore, maintaining appropriate storage conditions is foundational to preventing seafood poisoning.
