Episode 703: Billfish: Battle on the Line?

Along Central America’s coastline, ranging from Guatemala south to Panama, recreational fishing is big business. The unique oceanographic conditions of the eastern tropical Pacific make the area one of the best spots in the world for big game anglers to hook billfish. But intense pressures from commercial fishing operations have taken their toll on the numbers of sailfish and marlin in the region. Scientists with the University of Miami Billfish Research Program are using an ecosystems approach to study the animals, by integrating complex oceanographic data with high tech research tools. The ultimate goal is to develop local and region-wide conservation initiatives that ensure billfish populations remain sustainable for years to come.
