Shark fins are just tasteless cartilage with fibrous protein collagen. Chinese believe that shark fins can boost sexual potency, enhance skin quality, and even prevent heart disease. But the benefits of shark fins have never been significantly proven, nor has shark cartilage been reviewed by the U.S Food and Drug Administration (FDA). Entrepreneurs in Taiwan even substitute shark fins with Tilapia fins due to their bland similarities. But this hasn't stopped the massacre, yet.
The group targeted seven shark species around South Florida for the experiment. The sharks were temporarily caught and brought alongside the vessel for non-lethal tissue collection, whereby a 2 X 2 cm clip was removed from the trailing edge of the first dorsal fin, and a 4mm muscle biopsy sampled from the hepaxial muscle on the shark's left flank. All captured animals were later released. A few Great Hammerhead Sharks samples, however, were obtained as a result of recreational fishing activities.

Is this a good news?
Definitely not for shark fin soup lovers, but it's a good news for me and the sharks.
