Project Goal

To monitor the harvest in tribal mainstem fisheries to meet requirements of the U.S. v Oregon Management Agreement.

Impacts

Increased information to support management decisions.

Background

Project funding helps maintain and in some cases expand the Zone 6 tribal catch monitoring program. The current program funding is not adequate to meet current needs. BPA funding will help stabilize and improve the reliability of catch estimates for Zone 6 tribal fisheries by increasing the collection of tribal catch data through increased sample rates and the use of new data collection methods. Tribal catch estimates are required in real time to properly manage fisheries for conservation and to fairly share the harvestable component of upriver runs between treaty and non-treaty fisheries. Estimates of the Zone 6 catch contribute to estimates of total exploitation rates for Columbia River stocks of concern that inform stock assessment models used in recovery planning and biological opinions. Reliable and timely catch estimates are necessary to assure model accuracy, track actual exploitation rates over time, and evaluate the performance of harvest management in meeting conservation and harvest goals specified in biological opinions and regional management agreements.

Project Tasks

  1. Enhance total catch monitoring of Zone 6 tribal fisheries.
  2. Generate total catch estimates based on monitoring data.
  3. Assess feasibility of collecting PIT tags from Zone 6 tribal fisheries.
  4. Report total catches from Zone 6 Tribal Mainstem Fisheries as part of the requirements of the U.S. v Oregon Management Agreement.
