Lionfish invasion threatens Bahia coast and Abrolhos Marine Park

The invasive lionfish (Pterois volitans) has triggered environmental alerts along the coast of Bahia, Brazil, following the capture of 440 specimens in Porto Seguro. Researchers and environmental agencies have confirmed the species' presence in the Abrolhos Marine National Park, a critical area for South Atlantic marine biodiversity.

Originating from the Indo-Pacific, the lionfish lacks natural predators in the Atlantic and reproduces rapidly. Experts, including biologist Carlos Hackradt from the Federal University of Southern Bahia (UFSB), warn that the species' voracious appetite for native fish and crustaceans threatens to deplete commercial fish populations, impacting both the local fishing economy and reef-based tourism. There are concerns that the invasion could spread southward along the Brazilian coast toward states such as São Paulo and Santa Catarina.

In response, Porto Seguro has implemented a municipal plan to combat the bioinvasion. The initiative includes a program to pay fishermen R$ 10 for each captured lionfish and is exploring ways to integrate the fish into the commercial food market, as the meat itself is safe for human consumption despite the animal's venomous spines.
