Using Acoustic Telemetry Monitoring Techniques to Quantify Movement Patterns and Site Fidelity of Sharks and Giant Trevally Around French Frigate Shoals and Midway Atoll

In the summer of 2000, an array of autonomous acoustic receivers was deployed at French Frigate Shoals (FFS) in the NWHI as part of a project investigating the movement patterns of tiger sharks (Galeocerdo cuvier) within the atoll, particularly in relation to the high seasonal abundance of potential prey (birds, turtles, seals).
