Brazil's Porto Seguro offers $10 for every lionfish caught as invasion threatens reefs and fisheries

Porto Seguro is paying people $10 for every lionfish they catch as the invasive species threatens the region's native reefs and local fisheries.

The reward program removed nearly 500 lionfish from local waters within a month. Authorities are taking steps to control the population before it grows beyond their ability to manage it.

Research initiatives are also being launched to examine how the invasion is affecting the region's coastline.
