The 2021 stock assessment of `r spp` (_`r spp_latin`_) in California waters estimated that the California population of `r spp` in 2021 was below the Minimum Stock Size Threshold (MSST), which is 25$\%$ of unfished spawning output for rockfish stocks [@Langseth_status_2021]. The California population was estimated to have declined below MSST starting in 1992, reached it lowest values in the mid-1990s, increased to near the MSST in the 2000s and early 2010s, and declined in recent years.

A draft rebuilding analysis was developed in 2021 based on the results of the 2021 assessment [@langseth_rebuild_2022], and was used to inform catch levels (i.e. ACLs) for 2023--2024 using an SPR = 0.55. Subsequently, it was determined that `r spp` was defined in the Groundfish Fishery Management Plan (FMP) as a coastwide stock, so `r spp` in California waters did not meet the criteria for an overfished declaration and a rebuilding plan was not required. Since the 2021 assessment, Amendment 31 to the FMP was approved by the Pacific Fishery Management Council in June 2023, recommending that `r spp` along the U.S. west coast be defined as three separate stocks corresponding to waters off Washington, Oregon, and California [@fed_registry_2023]. The recommended change to the FMP was finalized in September 2023 and the `r spp` stock off California was declared overfished in December 2023, necessitating an updated rebuilding analysis.

The recommended change to the FMP was adopted in November 2023 and the `r spp` stock off California was declared overfished in December 2023, necessitating an updated rebuilding analysis.

Given the assumed levels of depletion for `r spp` in California waters and the need for rebuilding, a range of alternative rebuilding strategies were examined and are described in this report. This analysis contains updated estimates for removals of `r spp` in California waters in 2021--2024, and applies the alternative rebuilding strategies starting in 2025.

The 2021 stock assessment of quillback rockfish (\emph{Sebastes maliger}) in California waters estimated that the California population of quillback rockfish in 2021 was below the Minimum Stock Size Threshold (MSST), which is 25\(\%\) of unfished spawning output for rockfish stocks (Langseth et al. 2021). The California population was estimated to have declined below MSST starting in 1992, reached it lowest values in the mid-1990s, increased to near the MSST in the 2000s and early 2010s, and declined in recent years.
