Shark fin soup (or shark's fin soup) is a Cantonese cuisine delicacy commonly served as part of a Chinese feast, usually at special occasions such as weddings and banquets as a symbol of wealth and prestige. The "finning" of sharks required to make this soup has been highly controversial. Some have called the practice brutal, and it is also named as a primary contributing factor in the global decline of many shark species. China's booming economy has resulted in a large increase in demand for shark fins, and this, combined with the importance of this predator in oceanic ecosystems, has exacerbated the problems that the practice is said to perpetuate.
