Much appreciated. Is your advice confined to prawn/shrimp only or any animal sea foods, e.g., marine fish (whole or pieces), scallops, mussels, octopus, squid, crab, etc., or all marine crustaceans or even all marine shellfish (e.i., crustaceans and mollusks)? (See the list below)
I had surely come across your useful advice about prawn/shrimp more than once before. It was the use of a far more general term "sea foods" that alerted me that this was perhaps something I haven't encountered or known.

http://en.wikipedia.org/wiki/Seafood Seafood is any form of sea life regarded as food by humans. Seafood prominently includes fish and shellfish. Shellfish include various species of molluscs, crustaceans, and echinoderms. Historically, sea mammals such as whales and dolphins have been consumed as food, though that happens to a lesser extent in modern times. Edible sea plants, such as some seaweeds and microalgae, are widely eaten as seafood around the world, especially in Asia (see the category of sea vegetables). In North America, although not generally in the United Kingdom, the term "seafood" is extended to fresh water organisms eaten by humans, so all edible aquatic life may be referred to as seafood. For the sake of completeness, this article includes all edible aquatic life.
The harvesting of wild seafood is usually known as fishing or hunting, and the cultivation and farming of seafood is known as aquaculture, or fish farming in the case of fish. Seafood is often distinguished from meat, although it is still animal and is excluded in a strict vegetarian diet. Seafood is an important source of protein in many diets around the world, especially in coastal areas.
Most of the seafood harvest is consumed by humans, but a significant proportion is used as fish food to farm other fish or rear farm animal. Some seafoods (kelp) are used as food for other plants (fertilizer). In these ways, seafoods are indirectly used to produce further food for human consumption. Products, such as fish oil and spirulina tablets are also extracted from seafoods. Some seafood is feed to aquarium fish, or used to feed domestic pets, such as cats, and a small proportion is used in medicine, or is used industrially for non-food purposes (leather).
