Overview

Study reveals dusky and Galapagos sharks adjust their foraging around fishing piers, highlighting human impact on natural behaviors.

Key Points

  • Dusky and Galapagos sharks frequently interacted with fishing piers, suggesting human influence on their behavior.
  • Sharks visited piers approximately every four days, with dusky sharks appearing in the afternoon and Galapagos sharks at dusk.
  • Acoustic telemetry and dietary biomarkers were employed to study the resource use of these shark species.
  • Results indicate minimal alteration of natural foraging behaviors, with incidental feeding being a minor influence.
