Shark Fin Genetics
Dr. Demian Chapman of the Institute for Ocean Conservation Science at New York’s Stony Brook University explains how DNA extraction from shark ﬁns can identify the species of shark and where the shark was born. DNA research is very important to shark conservation efforts because it provides accurate species identiﬁcation and can help identify which countries are exploiting sharks the most. Up to 73 million sharks are killed each year for their ﬁns to support the global ﬁn trade, according to the U.N. The ﬁns are used for shark ﬁn soup, an Asian delicacy retailing for approximately $100 (US) per bowl.
