September 22, 2017 — Earlier this year, United States senators put forth S.793, a bill they’ve named the “Shark Fin Trade Elimination Act”. With the noble goal of protecting shark populations, which are in decline all over the globe, the document proposes a total ban on the buying or selling of shark fins in the US. Sounds like an unambiguously good thing, right? Well, the straightforward answer to a problem is not always the best one – and some shark researchers worry that this approach could do more harm than good.
In a recently published paper, shark researchers David Shiffman and Robert Hueter argue that banning trade in fins would not prevent many shark deaths at all – but it might hinder successful conservation practices, and sow confusion by misrepresenting the true threats to these animals. What they recommend instead is prioritising the continued sustainable management of shark fishing.
The finning issue
Let’s start with the broad problem: sharks are in trouble. And losing them is a threat not only for the ecosystems in which they serve important roles, but also for economies all over the globe that rely on them for food, including the United States. Worldwide, many populations are dwindling, their decline driven largely by overfishing, including hunting for meat, bycatch, as well as the lucrative fin trade, which supplies demand in some countries for a delicacy known as shark-fin soup.
This fin trade has led to a phenomenon called shark finning. As the bill describes, “Shark finning is the cruel practice in which the fins of a shark are cut off on board a fishing vessel at sea. The remainder of the animal is then thrown back into the water to drown, starve, or die a slow death.” This practice is not only cruel, but also wasteful – in contrast with conservative shark-fishing practices that make use of meat and parts from the entire body.
Shark finning has actually been banned in the US since the 1990s, but as long as the animal’s body is not discarded at sea, fishers are generally free to do what they will with the fins; indeed, these are typically harvested along with the meat. The new bill, however, presented by Senator Cory Booker of New Jersey, proposes a total ban on possessing, transporting, selling or purchasing shark fins, under threat of a fine of up to $100,000 or more.
