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

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
