To store thawed shrimp, unwrap, place them in a bowl covered with a wet paper towel, refrigerate, and prepare and eat them the same day. Frozen shrimp can be stored in its original wrappings in the freezer for up to two months. Take out and use shrimp as you need them, then reseal the bag and return it to the freezer. To thaw, unwrap, place shrimp in a bowl or saucepan, cover, and let thaw overnight in the refrigerator. To more quickly, wrap shrimp in waterproof plastic and place them in a sink with cool running water, allowing about 1/2 hour per pound (454g). For fastest thawing, use the defrost cycle of your microwave, allowing 2 to 5 minutes per pound (454g), with equal standing time in between zaps.
