$21M Black Market Seahorse Smuggling Booms Despite Global Bans

VANCOUVER, Canada — Dried seahorses worth more than $21 million have been seized worldwide in what researchers are calling one of the largest documented cases of marine wildlife trafficking. Despite international protections that should have stopped the trade years ago, smugglers moved nearly 5 million seahorses through a sophisticated network spanning 62 countries between 2010 and 2021, and those are just the ones authorities managed to catch.

New international research published in Conservation Biology reveals the staggering scope of illegal seahorse trafficking by analyzing online reports of government seizures over an 11-year period. With such mass amounts of illegal smuggling happening, are international wildlife protection laws actually effective?

Seahorses were the first genus of marine fishes to be listed under CITES, the international treaty designed to prevent species from becoming extinct due to trade. Since 2004, moving seahorses across international borders without proper permits has been illegal. Yet the seizure data shows trafficking actually increased over time rather than decreased.

The reported number of seizures and the number of seahorses seized increased over time, the researchers found. In 2019 alone, authorities confiscated more seahorses than in some entire previous years combined.

Seizures represent only a tiny fraction of actual smuggling. Most illegal shipments slip through undetected, meaning the real scope of seahorse trafficking could be astronomical.

Following the Money Trail

Individual dried seahorses sell for about $5 each on the black market, researchers discovered. That might not sound like much, but when smugglers move hundreds of thousands at a time, the profits add up quickly. The median number of seahorses per seizure was 700 (range 1–476,000) individuals, and the total number of seized seahorses across the database was calculated to be ∼4.93 million individuals.

Most seahorses end up in traditional Chinese medicine, where they’re believed to treat everything from asthma to sexual dysfunction. China emerged as the primary destination for smuggled seahorses, receiving shipments from across Africa, Asia, and Latin America.

Belgium surprisingly became a major transit hub for seahorse smuggling, though researchers note this finding may reflect data collection bias since European Union reports were more comprehensively included in their analysis. Peru also emerged as both a source and unexpected transit location, suggesting smuggling networks are more complex than previously understood.

Airports, Luggage, and Massive Sea Cargo

Researchers found that while most seizures happen at airports, typically involving passengers carrying seahorses in their luggage, the largest shipments move by sea cargo. Cargo, especially sea cargo, saw the largest seizures by number of seahorses, followed by commercial and private settings like warehouses and houses.

One seizure alone contained 476,000 seahorses. To put that in perspective, that’s nearly half a million individual animals in a single shipment.

Security screening at airports makes luggage seizures more likely, but vast shipping containers offer smugglers a way to move enormous quantities with little risk of detection. Most shipping containers are never inspected, and when they are, authorities typically focus on drugs, weapons, and human trafficking rather than wildlife.

Why Bans Aren’t Working

Most enforcement happens at destination countries rather than where animals are originally caught and exported. Seizures were reported to occur in various settings, most frequently airports, but typically after seahorses had already traveled thousands of miles from their ocean homes.

Combatting Illegal Wildlife Trade (IWT) requires enhanced enforcement in source countries. The seahorse seizures we examined mirrored those of other species, with most interceptions occurring during transit or at destination locations, rather than in source jurisdictions where export may receive less scrutiny.

This creates a whack-a-mole situation where authorities catch individual smugglers carrying relatively small quantities while massive operations continue to strip seahorses from coastal waters with impunity.

Countries like India, Indonesia, Malaysia, Peru, Philippines, Thailand, and Vietnam officially ended legal seahorse exports years ago in response to conservation concerns. Yet field surveys continue to document millions of seahorses being exported annually from these same countries through illegal channels.

Seahorses rarely travel alone. Three-quarters of seizures also contained other illegal wildlife products, including shark fins, elephant ivory, and pangolin scales. This suggests seahorse trafficking is part of a much larger criminal network that threatens multiple endangered species simultaneously.

Other marine wildlife was reportedly found with the seahorses in 42 seizures, most commonly sea cucumbers, shark fins, pipefish (a seahorse relative), and fish swim bladders (also known as fish maw).

Criminal organizations are essentially running one-stop shops for illegal wildlife, maximizing profits by diversifying their contraband.

The Enforcement Gap

When smugglers do get caught, consequences are minimal. Most seizures reportedly involved very few offenders. Only one person was implicated in over half the seizures in our database with relevant information, whereas 2–4 people were implicated in another one-third.

Catching individual couriers does little to disrupt the larger trafficking networks that continue operating behind the scenes. Information about actual prosecutions and jail sentences was extremely limited in the government reports researchers analyzed.

Seahorses play important roles in marine ecosystems, and their populations are already under pressure from habitat destruction and climate change. Uncontrolled trafficking adds another devastating threat.

“All countries must step up with strong deterrents — good detective work, determined enforcement, and meaningful penalties — to shut down the illegal seahorse trade,” says senior author Teale Phelps Bondaroff, director of research at OceansAsia, in a statement. “At the same time, we must continue using innovative research and investigation methods to uncover hidden networks and outpace traffickers.”

More than 30 seahorse species are traded internationally, with some populations declining rapidly in areas where fishing pressure is intense. Without effective enforcement of existing protections, several species could face extinction in the wild within decades.

The research also highlights broader problems with marine conservation. While charismatic land animals like elephants and tigers get significant attention and resources for anti-poaching efforts, marine species often slip through regulatory cracks despite facing similar threats.

Despite nearly two decades of legal protections and millions of dollars spent on conservation programs, criminal networks continue to decimate seahorse populations with little fear of meaningful consequences. Unless enforcement strategies fundamentally change to target trafficking at its source rather than its destination, seahorses may become just another casualty of humanity’s insatiable appetite for wildlife products, regardless of the laws designed to protect them.
