Description

Abstract: The Marine Resources Program of the Oregon Department of Fish and Wildlife conducted this project designed to provide information useful for management of fisheries for Black Rockfish. Results from this work were utilized in two federal stock assessments for Black Rockfish (Sampson 2007, Cope et al. 2016). This project received federal funding support from Sport Fish Restoration Grant F-186-R-10 from 2002 through 2013. The 2013 Annual Progress Report presents information for all of the years that the project received federal funding, with a focus on the twelfth and final year of tagging operations and results from eleven years of tag recoveries. Despite the lack of federal funding, ODFW continued to collect data necessary to make estimates for the following recovery year, which ended June 30, 2014. Those data were utilized in the assessment of the Oregon stock of Black Rockfish in 2015 (Cope et al. 2016). This document provides an update to the 2013 Annual Progress Report. It includes a table of the results for an additional recovery year. The table that provides information from this study in the Assessments of California, Oregon and Washington stocks of Black Rockfish (Sebastes melanops) in 2015 by Cope et al. (2016) was added to this document as part of Appendix A, in the hope that it will allow the reader to more easily understand the importance of this work to fishery management. The following text, with minor modifications for clarification and a note about the use of results by Cope et al. 2016, is from the Annual Progress Report submitted in 2013.

Purpose: This Annual Progress Report for Sport Fish Restoration grant F-186-R-10 summarizes 12 years of tagging and 11 years of tag recovery completed for this project. The study provides estimates of annual recovery and survival rates of tagged fish as well as annual exploitation rates and population abundance estimates of Black Rockfish for the study area. The project study design requires tagging a cohort of Black Rockfish each year before June 30, and then examining fish caught in the sport fishery to recover tagged fish during a recovery year from July 1- June 30. The report’s totals, analyses, and summaries are based on the study design. The grant-funding year, October 1 to September 30, differs from the project study year. The Annual Project Performance Report submitted along with this progress report provides an account of work accomplished with the grant funds during the grant period.
