Brazil has quietly become the world's largest importer and consumer of shark meat, creating a profound contradiction as the nation simultaneously attempts to lead international marine conservation efforts. Millions of Brazilians buy this meat every week at supermarkets and fish markets under the generic name cação, completely unaware that they are eating threatened apex predators. This massive domestic demand actively undermines global conservation policies, turning the country into a primary financial engine for the global shark trade while local regulations focus almost entirely on protecting domestic waters rather than addressing international supply chains.
The reality on the ground is stark. Walk into any major supermarket in São Paulo or Rio de Janeiro, and you will find neat, frozen trays of white fish fillets labeled simply as cação. It is cheap, boneless, and lacks the distinct fishy odor that deters some buyers. Parents feed it to toddlers. Schools serve it in lunches. It is the perfect mass-market seafood commodity, except for one detail. Cação is not a specific species; it is a linguistic mask for sharks and rays, many of which are facing imminent extinction.

The Linguistic Mask Keeping the Trade Alive
The use of the word cação is not an accident of local dialect. It functions as a highly effective marketing shield that deters consumer scrutiny. Decades ago, the term referred primarily to small coastal sharks caught by artisanal fishermen. Today, the label covers a vast international influx of shark meat, including blue sharks, shortfin makos, and hammerheads.
Public awareness remains low because the industrial seafood complex prefers it that way. Surveys conducted by marine biologists across major Brazilian metropolitan areas consistently reveal that over half of regular cação consumers have no idea they are eating shark. When consumers do discover the truth, their reaction is often shock. Shark is perceived as an exotic, potentially dangerous predator found in nature documentaries, not a cheap Tuesday night dinner. More analysis by NBC News delves into similar views on this issue.
By keeping the consumer in the dark, the industry avoids the ethical backlash that has hampered the sale of shark fins in Asia and Western nations. The global anti-finning campaigns of the last two decades successfully demonized the practice of slicing off a shark’s fins and dumping the living animal back into the sea. However, those campaigns inadvertently incentivized a different economic model. Instead of discarding the carcass, industrial fishing fleets began landing the entire animal to exploit the emerging, uncritical market in South America.
How Global Prohibitions Fueled the Brazilian Market
The international regulatory framework designed to protect sharks has fundamentally reshaped the economics of industrial fishing. When international bodies passed stricter regulations against finning, they required fleets to bring the full shark back to port if they wanted to sell the fins. This created a logistical problem for longline vessels from Spain, Portugal, Japan, and Taiwan. Shark meat takes up valuable freezer space that could otherwise be used for high-value species like tuna or swordfish.
Shark meat is inherently cheap because it has historically been viewed as a byproduct. To clear out their freezers and monetize this byproduct, international fleets needed a massive dumping ground. Brazil, with its large population and struggling economy, offered the perfect destination.
Importers discovered they could buy frozen shark trunks from European and Asian fleets for a fraction of the cost of local whitefish like hake or cod. The trade data reflects this shift. Over the past two decades, Brazil's imports of shark meat skyrocketed, making it the destination for a significant portion of the global shark longline catch. The country effectively subsidized the continued survival of international shark fishing operations by providing a profitable outlet for the meat, ensuring that the entire shark remains a viable commercial target.
The Policy Split Between Domestic Waters and International Ports
The Brazilian government has tried to project an image of an environmental leader on the global stage. It has pushed for the creation of marine sanctuaries in the South Atlantic and championed the inclusion of various shark species under the Convention on International Trade in Endangered Species. Within its own territorial waters, Brazil has enacted strict regulations, banning the targeted fishing of several threatened species and enforcing rules on bycatch.
This creates a glaring policy disconnect. While a Brazilian fisherman can face heavy fines or arrest for landing a threatened hammerhead shark, a commercial shipping container filled with tonnes of the exact same species can legally enter a Brazilian port from abroad, provided the paperwork claims it was caught legally in international waters.
Domestic enforcement is concentrated on the visible, easily monitored artisanal fleets along the coast. Meanwhile, the massive volume of imported meat moving through industrial customs checkpoints receives far less scrutiny. This creates a scenario where local fishermen suffer from conservation restrictions while the domestic market continues to consume the very species those restrictions are meant to protect, imported from fleets that operate with far less oversight.
The Hidden Health Crisis on the Dinner Plate
Beyond the ecological devastation, the mass consumption of cação presents a significant public health issue that regulatory bodies have largely ignored. Sharks are apex predators that occupy the top of the marine food web. Through a process known as biomagnification, they accumulate high concentrations of heavy metals and toxins throughout their long lifespans.
Independent testing of cação samples taken from Brazilian retail markets frequently reveals levels of arsenic and mercury that far exceed the maximum limits established by international health organizations and Brazil’s own health regulatory agency, Anvisa. Mercury is a potent neurotoxin that poses severe risks to human health, particularly to pregnant women and developing fetuses, where it can cause irreversible neurological damage.
The demographic consuming the most cação is often the most vulnerable. Because it is one of the cheapest animal proteins available in the seafood aisle, it is heavily purchased by low-income families and utilized in state-funded institutional menus, including public school lunch programs. The state is, in effect, purchasing toxic apex predators with public funds to feed vulnerable populations, driven by a lack of coordination between fisheries management, import customs, and public health agencies.
Tracing the Supply Chain From Sea to Supermarket
The journey of a shark fillet to a Brazilian dinner plate involves a complex global network. Industrial longline vessels operate thousands of miles out in the open ocean, deploying lines that stretch for miles with thousands of baited hooks. These hooks catch tuna and swordfish, but they also catch millions of sharks.
Once the vessels dock in transshipment hubs or European ports, the sharks are processed. The heads, guts, and fins are removed, leaving a frozen trunk. These trunks are loaded into refrigerated shipping containers destined for major Brazilian ports like Itajaí or Santos.
In Brazil, domestic processing plants thaw the trunks, skin them, and slice them into steaks or fillets. During this processing stage, any identifying features of the animal disappear entirely. The meat looks identical to any generic white fish. By the time it receives the cação label and enters the retail distribution network, the consumer has no way of knowing whether the fish was a abundant coastal species or a critically endangered oceanic whitetip. The supply chain relies on this deliberate erasure of identity to maintain its profit margins.
The Institutional Inertia Blocking Reform
Correcting this crisis requires tackling entrenched economic interests and bureaucratic inertia. The seafood industry benefits from the ambiguity of the current labeling laws. Tightening regulations to force companies to identify the exact species of shark on the packaging would immediately depress sales, as consumers confront the reality of what they are buying.
Furthermore, the government agencies responsible for oversight are often at cross-purposes. The Ministry of Fisheries focuses on maximizing production and economic yield, while the Ministry of Environment pushes for conservation. This institutional divide paralyses effective policy creation. True reform would mean implementing strict traceability requirements from the point of capture to the retail counter, alongside a comprehensive public education campaign to retire the deceptive cação label once and for all. Without these measures, international conservation pledges remain empty rhetoric, canceled out by the relentless demand of the domestic market.
