Caught in Southeast Alaska with shrimp pots, de-headed, and individually frozen at sea with the shell still on. That's it. Bonus: spot prawns don't need to be deveined! Comes in an Alaska Select 5 lb box with a plastic liner, frozen individuals are easy to divide into smaller portions for later or giving away. Note the product is an "ocean-run", meaning they have not been sorted for size. You'll get a variety of sizes and some will be smaller and some will be larger. Nature!
