THE BATTLE

BLACK MARLIN

ISTIOMPAX INDICA

Black marlin (Istiompax indica) are the fastest fish in the ocean and among the largest billfish, growing to almost 5m. They are a prized target for sport fishers who generally practise catch-and-release. However, the impacts of fishing on individuals and their populations remains unknown.
