On a humid Tuesday evening in Belém, the line in front of a tiny street stall is longer than the one at the burger chain across the avenue. The smell hits first: something smoky, fatty, almost sweet. A woman in a faded Flamengo jersey holds a plastic plate loaded with grilled fish, cassava flour and lime. “Pacu,” she shrugs when asked. “Used to be food for who had no money. Now everyone wants it.” Around her, delivery guys in orange jackets wait, helmets under their arms, checking their apps and laughing between bites. The vendor, hair tucked under a cap, flips thick fillets over hot coals with a kind of quiet pride.
She knows the joke has flipped.
The “poor people’s fish” is suddenly the star of the show.
From neglected river fish to social media darling
In Brazil, pacu has spent decades in the culinary shadows, overshadowed by sleek salmon fillets and frozen tilapia. It was the fish of riverside communities and small-town markets, often sold whole on newspaper sheets and eaten with more bones than ceremony. For a long time, middle-class families in big cities saw it as “cheap” food, a second choice, something you bought when your salary ran out before the month.
Then food prices exploded. Beef became a luxury. Even chicken started to hurt the wallet. Little by little, pacu reappeared on urban tables, this time not out of shame, but out of strategy — and curiosity.
In São Paulo’s outskirts, nutritionist and single mother Carla, 32, remembers the shift clearly. In 2021, she stopped buying steak for her two kids. At the supermarket, she stood in front of the meat aisle, calculator in hand, and walked away empty-handed. A few steps later, in the fish section, a whole pacu stared at her from the ice. It cost half the price of a tray of beef.
She took it home, roasted it with garlic, lemon and coarse salt. The kids devoured it. The next week, she filmed the recipe for TikTok. Her video — “Cheap fish that feeds the whole family” — hit 1.2 million views in a month. Comments flooded in: “My grandma used to cook this!”, “I thought pacu was dangerous,” “Where do I find it?” A forgotten fish quietly went viral.
The boom isn’t just nostalgia. There’s numbers behind it. Pacu is rich in protein, omega‑3 and B vitamins, and farmed pacu usually has lower mercury concentrations compared with many large ocean fish. It grows fast in ponds and rivers, requires less feed than cattle, and puts less pressure on forests and pastures. For families squeezed between higher electricity bills, rent and fuel, **a fish that is cheap, filling and relatively safe** starts to look like a small piece of economic sanity.
Food trend analysts talk about “democratizing nutrition,” but down in the open-air markets, the logic is simpler. If something feeds everyone at the table, doesn’t blow up the budget and feels like “real food”, it gets a second chance.
How Brazilians are reclaiming pacu — and cooking it better
The first secret that circulates in WhatsApp groups and family chats is almost embarrassingly simple: ask the fishmonger to score the pacu. Vertical cuts along the thickest part of the flesh, all the way down to the bone, transform a bony river fish into a crispy, accessible meal. Salt seeps in. Bones soften. Skin turns into a snack.
On weekends in Mato Grosso do Sul, entire pacus are butterflied and opened like wings on wire grills, drenched in garlic, coarse salt and a squeeze of lime. The flames lick the fat that runs between the muscles, basting the fish from inside. The result is rich and smoky, closer to barbecued ribs than to the dry, sad fish many people grew up with.
For home cooks rediscovering pacu after decades of bad school-canteen memories, the fear is always the same: bones, smell, “muddy” taste. There’s also the trauma from the years when river fish were tied to pollution scandals and mercury scares in the Amazon. So people overcook it, scrub it with vinegar until it’s rubbery, drown it in strong spices to “hide” the flavor.

Let’s be honest: nobody really does this every single day. On a Wednesday night, you want something that goes into the oven and comes out edible, without two hours of deboning. That’s why recipes that use pacu in moquecas, stews or fillets are growing fast online. Cut into thick slices, simmered with coconut milk, tomatoes, cilantro and onions, the fish becomes tender and forgiving. It’s cheap comfort food that doesn’t taste like a compromise.
In small river towns, older cooks watch this wave with a quiet, amused satisfaction. They’ve known pacu’s potential for generations.
“People from the city used to turn up their noses,” says Dona Marinalva, 64, from a riverside community near Porto Velho. “Now they arrive with food bloggers and cameras. I cook the same way my mother taught me. The fish didn’t change. People changed.”
She serves her pacu fried in lard, with farofa and a slice of orange to cut the fat. On her plastic tablecloth, the fish is the opposite of trendy — it’s just lunch.
To help new fans, nutritionists and chefs are repeating a few basic rules:
- Buy from a trusted source: ask if the fish is farmed or wild and where it comes from.
- Use high heat: grill, roast or fry so the skin crisps and the fat renders.
- Keep it simple: salt, acid (lime or lemon) and one or two herbs are enough.
- Respect the bones: serve it in big pieces and eat slowly, especially with children.
- Rotate species: don’t eat pacu every day; variety lowers the risk from any contaminants.
*None of this is fancy cookbook stuff; it’s the same quiet wisdom you hear at any riverside bar by late afternoon.*
Beyond the plate: what this “poor people’s fish” says about Brazil now
Pacu’s comeback touches more than recipes. It reveals a country caught between economic pressure and a search for dignity at the table. When beef is priced like a luxury product and ultra-processed snacks are sold as the “cheap option,” going back to a river fish your grandmother ate can feel strangely modern. It’s food that resists the idea that good nutrition must come wrapped, branded and frozen.
There’s also a rural pride woven into every grilled pacu selfie posted from the Pantanal or the Amazon. Young people who once dreamed only of imported salmon now celebrate the fish their parents caught in wooden boats. In their captions, you read a mix of irony and affection: “From poor people’s fish to influencer food,” “My grandma was right,” “Rivereira cuisine is the future.” When a nation returns to something it once despised, it usually means values are shifting under the surface.

FAQ:
- Is pacu safe to eat with all the news about polluted rivers?Most farmed pacu sold in supermarkets and fishmongers is regularly monitored and considered safe; ask about origin and alternate it with other fish to reduce long-term exposure to any contaminants.
- Does pacu have a strong or “muddy” taste?Fresh pacu handled on ice has a mild, slightly sweet flavor; strong or muddy notes usually mean the fish isn’t very fresh or wasn’t stored properly.
- How can I deal with all the bones?Ask for the fish to be butterflied and scored, cook it on high heat, and serve in large pieces so you can easily see and remove bones while eating.
- Is pacu really more nutritious than cheap processed meats?Yes, it offers quality protein, good fats and minerals without the excess sodium, additives and saturated fats common in processed sausages and nuggets.
- Can I freeze pacu at home without losing quality?Yes, pat it dry, wrap tightly or use a freezer bag with the air pressed out, and use it within two to three months for best texture and flavor.
