UH Oʻio Tagging Project

December 28, 2012

The Oʻio Tagging Project of the Hawaii Cooperative Fishery Research Unit, University of Hawaii, began in 2003 with the following objectives:

  1. Determine the ecological, biological, and cultural importance of oʻio in Hawaiʻi.
    • Through samples collected from volunteer anglers and fishing tournaments we are examining the diet, age, and spawning cycle of oʻio . These projects are finishing up and will be available to the public later this year.
  2. Encourage a greater conservation ethic for marine resources through the tagging and release of captured fish.
    • We give out and collect tagging data, and continue sponsorship of a tagging category in many nearshore fishing tournaments.
  3. Foster collaboration and trust between the fishing community, scientists, and resource managers.
    • We participate in local fishing club meetings and outings. We present project findings at fishing expos, school meetings, youth fishing events, and at public forums such as the Hanauma Bay Lecture Series.
  4. Provide information on the oʻio fishery by analyzing angler-based data.
    • We analyze data to provide information on the recreational oʻio's fishery including catch-per-unit-effort, size distributions, location and time of capture.

Here are some results for May 2003 – July 2012:

  • Fishing hours reported: 6,161
  • Anglers registered: 515
  • Oʻio tagged: 2,304
  • Oʻio recaptured: 57

Tags were applied on Hawaii, Kauai, Lanai, Maui, Molokai, and Oahu.

Through the dedication of our volunteer anglers we are achieving our goals and growing beyond our expectations. Thank you all for your help and hard work.
