The knowledge flows both directions—from the wild to the tank, and back out to the field.
The facility holds 5 million liters of water, 453 animal species, and has successfully bred 100 species including 32 Pantanal-native species under human care. The congress theme 'A dive into conservation: science, society and environment' will feature discussions on applied research, wildlife protection strategies, and zoo/aquarium management practices.

Bioparque Pantanal in Campo Grande will host Brazil's 49th Zoo and Aquarium Congress in May 2026, bringing together specialists to discuss conservation, animal management, and environmental education at the world's largest freshwater aquarium.
In May 2026, Campo Grande will become the gathering place for Brazil's conservation establishment. The Bioparque Pantanal, built inside the Parque das Nações Indígenas, will host the 49th Congress of the Brazilian Association of Zoos and Aquariums from May 26 to 30, drawing researchers, students, and wildlife professionals from across the country to discuss the work of keeping animals alive in human care and using that work to protect species in the wild.
The facility itself is the draw. Opened in 2022, the Bioparque holds five million liters of water across 239 tanks—31 of them open to visitors, the rest devoted to the unglamorous work of keeping animals healthy: quarantine, breeding, water treatment, veterinary care. The complex spans 21,000 square meters and currently houses 453 animal species, a number that has grown as the facility has matured. What began as a public aquarium has become something more complicated: a place where tourism, research, and conservation operate in the same building, in the same moment, often in the same tank.
The congress theme—"A dive into conservation: science, society and environment"—signals what the gathering will actually be about. Yes, there will be talks on biodiversity and animal management. But the real work happens in the sessions on technical photography, institutional communication, wildlife handling protocols, and environmental education strategies. These are the unglamorous skills that keep zoos and aquariums functioning as something other than spectacle. The program will bring together biologists, veterinarians, zookeepers, and public administrators to share how they solve problems that don't make headlines: how to maintain water quality for 453 species, how to breed animals whose natural habitats are shrinking, how to tell the public why any of this matters.
The Bioparque's own track record gives the congress concrete ground to stand on. In March 2026, the facility announced it had successfully bred 100 species under controlled conditions—not in the wild, but in tanks and enclosures where every variable can be measured and adjusted. Thirty-two of those species are native to the Pantanal, the vast wetland that gives the facility its name and its purpose. These aren't abstract achievements. They represent years of monitoring, veterinary work, careful feeding, behavioral observation, and genetic management. The facility also claims to maintain the largest living genetic bank of freshwater species, though the institution has not published independent verification of that claim.
Why the Pantanal matters here is worth understanding. The wetland faces real pressures: changing rainfall patterns, fires, habitat loss, environmental stress documented by research institutions across Brazil. When a species reproduces in a tank at the Bioparque, researchers can observe its breeding cycle, behavior, genetic needs, and environmental requirements in ways that inform conservation strategies for wild populations. The knowledge flows both directions—from the wild to the tank, and from the tank back out to the field.
For Mato Grosso do Sul, hosting this congress serves a larger strategy. The state government has positioned the Pantanal as a focal point for tourism, research, and environmental education. The Bioparque is the physical embodiment of that vision: a place where visitors walk through exhibits of Brazilian freshwater life while, behind the scenes, scientists and technicians work on the harder problem of keeping those species alive as their natural homes change.
The congress will create space for that knowledge to circulate. Researchers from universities, zoos, and conservation agencies across Brazil will present studies, discuss methodologies, and build networks. Students will see what the work actually looks like. Professionals will learn from each other's mistakes and successes. For the Bioparque itself, hosting the event means opening its technical spaces—the quarantine areas, the breeding tanks, the water treatment systems—to scrutiny and conversation. It's a moment when a facility that operates mostly out of public view becomes a classroom.
What happens in May 2026 will not be dramatic. There will be no announcements of species saved or habitats restored. Instead, there will be careful talk about how to keep animals healthy, how to breed them responsibly, how to use that breeding to maintain genetic diversity for species that may one day need to be reintroduced to the wild. It is the unglamorous work of conservation, and it is the work that will determine whether species survive the next fifty years.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that this congress happens at the Bioparque itself, rather than in a hotel ballroom in São Paulo?
Because the congress becomes a working seminar. Researchers can walk from the lecture hall into the tanks, see the actual animals, talk to the people who feed them every day. The knowledge isn't abstract—it's rooted in the place where the work happens.
You mention that 32 of the 100 successfully bred species are from the Pantanal. Why is that number significant?
It shows the facility is doing what it was built to do: maintain populations of species that are under pressure in their natural habitat. The Pantanal is changing—fires, drought, habitat loss. If those 32 species disappear from the wild, they still exist here, with genetic diversity preserved, breeding protocols documented. It's a backup plan.
The source mentions the facility claims to have the largest genetic bank of freshwater species, but notes there's no independent verification. Why include that caveat?
Because institutions often make claims about their own importance. The claim might be true. But the reader should know that the Bioparque said it about itself, not that an outside body verified it. That's the difference between marketing and fact.
What's the actual work that happens behind the scenes that visitors don't see?
Water chemistry, veterinary care, feeding protocols tailored to each species, behavioral observation, genetic management. If a fish is sick, someone notices. If a breeding pair isn't reproducing, researchers adjust temperature, light, diet. It's constant, invisible labor that makes the visible part possible.
Why would a state government invest in this kind of facility?
Tourism, yes—people visit. But also because the Pantanal is a global ecological asset, and Brazil wants to be seen as protecting it. A facility that breeds Pantanal species, that does research on them, that educates visitors—that's a way of claiming stewardship. It's both genuine conservation work and strategic positioning.
What should readers watch for after the congress ends?
Whether the knowledge shared actually changes how zoos and aquariums operate. Whether the networks built lead to collaborative breeding programs. Whether the Bioparque's own work expands. A congress is only useful if something changes because of it.
