A surge in fish attacks has partially closed Praia da Figueira, a major tourist destination in Bonito, Brazil.
Known as the countrys ecotourism capital, Bonito reported at least 30 cases of fish bites in 2025.Most incidents occurred at the artificial lagoon of Praia da Figueira, where visitors float to observe pacu, dourado, matrinx, and tambaqui fish.
The tambaqui, an Amazonian species with strong teeth, caused severe injuries, including five finger amputations.The lagoons management faces scrutiny for introducing tambaquis into the area, a move experts call an environmental violation.
Stress and human feeding behaviors likely triggered the fishs aggression.Tourists feeding fish near submerged kiosks may have confused tambaquis into biting fingers mistaken for food.
One victim, a retired teacher, lost part of her finger while another required nine stitches after a bite.The Mato Grosso do Sul Environmental Institute (Imasul) ordered the lagoons closure on March 26.

Bonitos authorities also investigate potential environmental violations, including water diversion from the Formoso River to fill the lagoon.Critics argue lax oversight allowed unsafe conditions to persist at popular attractions.
Some tourists vowed not to return after traumatic incidents.
Tambaquis are among Brazils most farmed fish due to their adaptability and herbivorous diet.Experts say their behavior in Bonito is unusual and likely influenced by human activity.
As investigations continue, Bonitos tourism industry faces pressure to improve safety and environmental practices while preserving its reputation as a premier ecotourism destination.
