To track the juvenile blacktip sharks, researchers tagged them with acoustic transmitters and monitored their movements throughout Hilo Bay from July 2022 to January 2024. The study’s results suggest this population of blacktip sharks reside predominantly within Hilo Bay for the first few years of their life. The study focused on oceanic blacktip sharks (Carcharhinus limbatus), one of two blacktip shark species found in Hawaiʻi. A team of UH Hilo marine researchers monitored movements of juvenile blacktip sharks from July 2022 to January 2024. Researchers are now expanding their work to examine 15 years of shark and ray population trends in Hilo Bay.
