Inside an inspection facility in Hong Kong in 2018, shark biologist Diego Cardeñosa stared at dozens of large white bags. They were stacked, sometimes six or seven high, beneath strip lights hanging from the ceiling. Each bag weighed more than 50 kilograms (110 pounds) — and was stuffed with shark fins. “It was the first time I saw that,” Cardeñosa wrote in an email to Mongabay. “Obviously, as a student, it was a shock and [a] reality check for me.” Cardeñosa, now a shark trade researcher at Florida International University in the U.S., lived in Hong Kong in 2018 and returned repeatedly from 2015 to 2020 as part of his PhD field research at Stony Brook University, also in the U.S. He helped train law enforcement in Hong Kong to use a mobile DNA kit to identify shark species whose trade is regulated under CITES, a treaty signed by 184 countries and the European Union that establishes rules for international trade in imperiled plants, wildlife, and their products. Many of the fins Cardeñosa saw in Hong Kong back in 2018 were cut from silky sharks (Carcharhinus falciformis). Like all shark species, silkies are heavily hunted for their fins, which are used in shark fin soup in China and Southeast Asia; they are also netted in vast numbers as bycatch. Shark numbers have cratered over the last 50 years. A 2024 study found that overfishing has halved populations of roughly 1,200 species of sharks and rays since 1970.

It is far easier than one might expect to access the illegal wildlife trade in Canada. Chris Shepherd, a senior conservation advocate with the Center for Biological Diversity, knows this firsthand. On a recent call with Mongabay, he recounted attending a reptile fair in Canada and speaking to a seller who told him he regularly received shipments of “anything you want” from the U.S. “I asked him about a few illegal [Indonesian] animals … he said, ‘Oh, I just sold out of those. I’ll get more next weekend,’” Shepherd said. Globally, the black-market wildlife trade is driving many species toward extinction, and it’s extremely lucrative: Poaching and illegal sales of wildlife are valued at about $20 billion annually, according to a paper published last year in the journal Ecology and Evolution. Meanwhile, the legal trade is estimated at $220 billion a year, trading at least 70,000 species, that are often shipped or smuggled in vast numbers. Meanwhile, there’s little data on sustainability, according to a broad international study. Beyond the conservation concerns, this trade also poses a serious public health threat. Importing animals from around the globe without proper oversight can expose both humans and livestock to zoonotic diseases that jump between species. Examples include Ebola, tuberculosis, rabies, avian influenza and COVID-19, to name a few. The illegal wildlife trade is also a national security issue because of the perpetrators: International organized crime syndicates run these black-market operations, which can only function through bribes, fraud, complicity and corruption.
