Seafood is a plant or animal originally from the sea that is used for food by humans.http://www.dictionary.com The number of varieties of seafood is ever changing, as new ways are discovered to eat plants or fish previously thought inedible, and new plants and fish are consistently being discovered in various parts of the world.
The four main categories of seafood are fish, roe, shellfish, and plants. Whether these are going to be served is going to depend on the region of the world and body of water they originatedhttp://www.thenibble.com/reviews/main/fish/seafood/seafood-glossary.asp. For example Japan is a country that is surrounded entirely by water and has access to an almost unparalleled variety of seafood. It is not uncommon for all 4 of the main categories to be served in a single dish, and depending on the sushi dish it can all be on one bite of foodhttp://www.thenibble.com/reviews/main/fish/seafood/sushi-glossary.asp. Whereas in the seas surrounding Alaska, shellfish and regular fish are abundant. Crab, lobster, halibut and salmon are fished in large numbers, therefore in Alaska and surrounding areas you will find a higher number of these types of seafood availablehttp://www.squidoo.com/alaska-seafood.
History and Background
Fishing dates back as far as 60,000 to 70,000 years ago when Africans would carve tools from bones and use them to fish. Fishing has also played an integral part in humans expanding the globe. As people learned to more efficiently get their food from the sea, they were free to go on treks for as far as they wished since all they needed to do was to follow the coasthttp://news.bbc.co.uk/2/hi/science/nature/5398850.stm.
Though it has slowed down significantly throughout history, whaling was also a major part of the seafood and fishing industry. Whaling dates back thousands of years to native tribes in Russia, Europe, and North America who used to butcher and use the entire whale. The Makah, a Native American tribe, would use Humpback whales for food and Gray whales for oil. When on a whale hunt they use to throw harpoons that had ropes with inflated seal bladders attached to them into the whale which kept it from diving. Once the whale died tribesmen would dive into the ice cold water and sew its mouth shut which would prevent air from escapinghttp://sportales.com/hunting/history-of-whaling/.
The whaling industry has since almost stopped entirely, and now only exists as "scientific study" and on the black market.
