Dear

Thank you for your participation in the Aquatic Resources’ “Ulua Tagging Project”. Fishermen’s supportand concern is essential to the success of this project. The information gathered through this project willhelp improve and strengthen resources for future generations to enjoy.

All fishermen who participate in this program whether tagging or in recovery of fish will be giveninformation pertaining to that particular fish. Periodic recaps of the project will be published in our“Current Line” newsletter available at various sporting goods stores or published in the Hawaii FishingNews. In the near future we plan to establish a web site in conjunction with the DLNR web page.

- Update growth curve information.

- Size distribution of fish caught and/or released by fishermen

- Stock distribution based on the numbers of fish tagged andrecovered

• Combined tagging efforts of volunteer anglers produces a large volume of tagged fish providing a large amount of data that can be used to assess the ulua and papio resources at minimal cost.

• Project provides common ground for both fishing and scientific communities to work together toward building a better resource for everyone.

• Management decisions are more easily supported/accepted by fishermen. They become part of the process by gathering information and data that they know and trust will impact management decisions that will best support their fishery. It’s a win-win situation.

Management Benefits

Future Goals• Increase recruiting effort for more volunteer anglers on all neighbor

islands.

• Gather more information on all other species of ulua, papio, and kahala, especially on the neighbor islands to assess the differences, if any , among species composition and distribution.

• Continue to assess the use of recovery data to monitor the conditions of nearshore resources.

• Expand the targeted species as requested by volunteer anglers.

• Expand general support to accommodate increasing public demands for continuous growth of the Ulua Tagging Project.

• As the project continues to grow and larger numbers of fish are being tagged, this opens the door for further research into determining standing stocks, exploitation rates, and spatial distribution of fishing efforts.
