The oceans, rivers and lakes have provided us with an abundance of fish, crustaceans and shellfish since time immemorial. Fish are generally considered to be tasty and healthy because of their high protein, mineral and vitamin content, without saturated fats. Shrimp are one of the most popular shellfish. There are many types, including king prawns, Dutch and Norwegian shrimp and the more 'exotic' shrimp such as Mexican and black tiger shrimp. Shrimp are primarily sold precooked in the U.S. They can be eaten cold or can be heated in all sorts of ways - the possibilities are endless.
