Longline fishing vessels unintentionally catch and drown sea turtles at rates threatening multiple species with extinction.
Sea turtles entangled on longline hooks experience drowning, severe hook injuries, and exhaustion. Those that survive entanglement may have internal injuries from swallowed hooks. Because sea turtles are air-breathing reptiles, the time between entanglement and drowning is brief. Circle hooks and fish aggregating devices without hooks can dramatically reduce both the number of turtles caught and the severity of injuries.
