Sharks are pulled onto fishing boats where their fins are cut off and their bodies are thrown back into the ocean as waste. A large percentage of these animals are still alive and suffocate. Even though less than 5% of the shark is fin, the rest is usually thrown away because of the economics of it. Shark meat must be properly refrigerated and takes up a lot of space on a boat. Fins, however, can be cut off, bundled, and hung to dry in large nets. It is the fin that produces the largest profit by far and can be sold for hundreds of dollars per pound.
