ObjectivesOLYMPUS DIGITAL CAMERA

The objectives of this project are to provide outreach and education on the biology and fisheries of ‘ō‘io and to foster collaboration and trust between the fishing community, scientists, and resource managers. We also encourage a greater conservation ethic through the tag and release of ‘ō‘io. The biological and ecological information on ‘ō‘io we collect will allow us to determine peak spawning seasons, diet, migration and habitat use of the ‘ō‘io, and the growth rates and aging of the ‘ō‘io.

Methods

Tagging kits are distributed to volunteer anglers and we ask for the following information:

  1. McCoy_FERLDate of the fishing trip
  2. Times of start and finish of fishing
  3. Location
  4. Species caught
  5. Fork Length
  6. The time that each fish was caught
  7. The fish weight (optional)
