My positionIn May, California passed a ban on the sale and distribution of shark fins. I support the ban, because even though shark fins are considered as a delicacy, shark finning is a cruel act , which should be stopped.

Basic information about sharksSharks, the top predators of the ocean, are regarded as an “eating machine” due to eating habits, ranging from fishes to humans. They have been around for 400 million years and play an important part in maintaining the marine food web.

What is shark finning?According to the Ecologist, “shark finning is the practice of cutting off the shark's fins and throwing the still living shark back into the sea to die”. Shark fins are one of the world’s most valuable fisheries products. And according to NGO WildAid, shark finning is responsible for the 90 percent decline in shark population over the last 50 years.

Bycatch Large numbers of sharks are taken as bycatch because of longline fishing, which is a method involving a long line attached with hooks.

Sharks’ growthSharks are particular vulnerable to overfishing due to their slow growth and late maturity. Accoridng to Current Science, “most large sharks do not reach sexual maturity until the age of seven years or later, and only give birth to a few pups each year”.

Shark fin soupShark fins are almost tasteless and the soup is always flavored with chicken stock. The soup is often served at important events such as weddings and state functions. Accorinding to the New York Times, it is estimated that “73 million are slaughtered solely for their fins to provide the shark fin soup that is so popular in Asia”. 

Status symbolAccording to the Ecologist, “In the next 10 years there will be up to 250 million relatively middle class urban-living people with disposable income in a highly aspirational culture, where the need and social benefits of showing off wealth are high. This will mean a potentially higher demand for shark fin soup because of the status it confers on both the giver and receiver.”

Faux shark fin soupAccording to KTSF, “Corey spent at least a year to create a combination of hydrocolloids to imitate the texture of real shark fins. Shark fin strands are made of broth that is cooked with traditional ingredients including chicken and Jin-Hua ham.”
