Shark finning is the act of removing fins from sharks. It is mostly done when shark is still alive. The sharks are sometimes thrown back to the ocean after removing their fins but they are still alive. since they are unable to swim properly, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. Shark finning at sea helps fishing vessels in increasing their profit. It also helps to increase the number of sharks harvested, as they only have to store and transport the fins, which is the most profitable part of the shark; the shark meat is bulky to transport. Some countries have banned this practice and require the whole shark to be brought back to port before removing the fins.
