Hawai‘i Ocean Observing System Large Animal Tracking (Ecosystem Stewardship Component of HIOOS) Kim Holland and John Sibert Hawaii Institute of Marine Biology and SOEST

Integrated Ocean Observing System Seven Societal Goals Improve the safety and efficiency of marine operations More effectively mitigate the effects of natural hazards Improve predictions of climate change and its effects on coastal populations Improve national security Reduce public health risks More effectively protect and restore healthy coastal marine ecosystems Enable the sustained use of marine resources

HIOOS Core Technology: Acoustic Monitoring

Hawaiian Archipelago Acoustic Array

Reef Fish Movements in Marine Protected Areas Carl Meyer – Hawaii Institute of Marine Biology Questions: (1) Are reef fishes long-term MPA residents? (2) Frequency of MPA boundary crossing? (3) Habitat breaks = natural barriers? Methods: Acoustic Monitoring Kealakekua Bay MPA (1) Reef fishes implanted with transmitters (2) Movements tracked with remote receivers Preliminary Results: (1) Most reef fishes are resident at Kealakekua MPA (2) Scale of movements varies among species (3) Some species cross MPA boundary daily (4) Reef fishes rarely cross major habitat breaks

Public Safety Implications of Shark Ecotourism Carl Meyer & Kim Holland – Hawaii Institute of Marine Biology Questions: (1) Do sharks follow boats back to shore? (2) Do sharks come into areas used for recreation? Methods: Acoustic Monitoring (1) Sharks implanted with transmitters (2) Movements tracked with remote receivers North Shore Oahu

Kim Holland et al. – Hawaii Institute of Marine Biology Tuna movements between FADs Kim Holland et al. – Hawaii Institute of Marine Biology Only the 2 fish that visited more than 2 FADs are represented on the map. The next 2 slides detail the movements of these 2 fish To note: one YFT went from S (leeward) to LL (windward) From CO, fish have gone to the leeward and the windward sides (CO  II & CO  V)

HIOOS Large Animal Tracking Goals? Provide data for enhancing ecosystem stewardship by; (1) Increasing monitoring coverage off Honolulu (2) Integrating physical oceanography (3) Modeling population dynamics of pelagic fishes
