In Águas da Prata, São Paulo, the practice of using slingshots to kill fish has come to light following reports from local residents and fishermen. The environmental agency, Companhia Ambiental do Estado de São Paulo (Cesteb), confirmed these allegations after conducting an inspection requested by the local environmental authorities. This illegal fishing method has raised significant concerns due to the horrific injuries it inflicts on aquatic life, including fractures and internal bleeding.

The slingshot fishing technique differs markedly from traditional angling, where hooks sometimes allow for the possibility of catch and release. Instead, slingshots employ projectiles like stones and metal spheres that cause intense trauma to the fish. Although some fish may escape after being hit, they often suffer painful injuries, leading to a slow and agonizing death.

The environmental implications of this practice are grave. The killing of fish in such a brutal manner disrupts the local ecosystem and can lead to a decline in fish populations, which are essential for maintaining ecological balance. Local authorities are now faced with the challenge of addressing this illegal activity while also educating the community about the importance of sustainable fishing practices.
