The subsequent time you purchase cat meals from the shop, take a have a look at the substances listed on the again. Should you see “fish,” “white fish” or “ocean fish,” your pet could be consuming shark meat. 

In a recent research revealed in Frontiers in Marine Science, researchers used DNA barcoding to check 45 completely different pet meals merchandise from Singapore. They discovered a couple of third of all 144 samples contained DNA from sharks, together with some from endangered species. Essentially the most frequent species the researchers recognized was the blue shark, adopted by the silky shark, which is listed as weak on the Worldwide Union for Conservation of Nature’s Pink Checklist.  

An identical research in 2019 discovered genetic materials from sharks in pet meals and cosmetics collected in the USA.

“Given the outcomes of a earlier research carried out within the U.S., we desired to see if endangered sharks are additionally bought in Asian pet meals,” say research authors Ian French and Benjamin J. Wainwright, who’re each researchers at Nationwide College of Singapore, in an announcement.

Most merchandise the researchers sampled used generic phrases like “fish,” “ocean fish,” “white bait,” or “white fish,” as a substitute of shark, per the research. Some listed “tuna” or “salmon,” and others didn’t embrace fish as an ingredient in any respect.

“Sharks weren’t listed as substances on any of the sampled merchandise examined,” the authors write. “Whereas this shouldn’t be unlawful or a required process, we argue that many pet house owners and lovers could be alarmed to seek out out that they’re probably contributing to the unsustainable fishing practices which have prompted large declines in world shark populations.”

International shark and ray numbers have dropped greater than 70 p.c within the final 50 years, principally due to overfishing, a research revealed within the journal Nature final yr discovered. In 2012, NBC Information’ Michael Casey reported as many as 70 million sharks are killed yearly for his or her fins. 

“We’re on the cusp of beginning to lose this historic group of creatures, species by species proper right here, immediately,” Andy Cornish, chief of WWF’s world shark and ray conservation program advised the Atmosphere Information Service final yr. “Beginning now, we’d like far better motion by governments to restrict fishing and produce these functionally essential animals again from the brink.” 

The authors write that shark meat could also be utilized in pet meals in an try to keep away from waste within the shark fin business, the place low-value carcasses are sometimes discarded. 

“If that is so, that could be commendable,” they write. “Nonetheless, we’re skeptical that that is the only cause that sharks find yourself in pet meals. Extra probably, their presence demonstrates the excessive fishing stress to which sharks are more and more subjected.” 

French and Wainwright counsel that higher labeling would permit shoppers to make extra knowledgeable choices about what they buy. 

“This in flip would profit shark populations by serving to to mitigate unsustainable fishing and useful resource use incompatible with their continued survival,” they write.
