The distinct population segment (DPS) of Yelloweye Rockfish Sebastes ruberrimus inhabiting the Puget Sound/Georgia Basin was listed under the Endangered Species Act (ESA) in 2010, and a formal recovery plan for the DPS was published by National Oceanic and Atmospheric Administration Fisheries in 2017. In this recovery plan, the biological criteria for delisting or downlisting were specified as certain levels of spawning potential ratio (SPR), a commonly used metric of equilibrium stock status for commercially exploited fishes. Although this metric can be estimated from length compositions, the combination of length data with a catch history (which was not previously available for this DPS) improves our understanding of population dynamics over time and allows us to estimate a different measure of stock status, relative (to unfished) spawning stock biomass (SSB), rather than only SPR.

数据有限的渔业评估方法揭示了华盛顿州普吉特湾列入濒危物种法的黄眼石斑鱼的开发历史和种群动态

黄眼石斑鱼Sebastes ruberrimus的独特种群分段 (DPS)栖息于普吉特海湾/乔治亚盆地的海鳅于 2010 年被列入濒危物种法 (ESA)，国家海洋和大气管理局渔业部于 2017 年发布了 DPS 的正式恢复计划。在该恢复计划中，除名的生物学标准或降级被指定为一定水平的产卵潜力比（SPR），这是商业开发鱼类平衡种群状态的常用指标。虽然这个指标可以根据长度组成来估计，但长度数据与捕捞历史的结合（以前不能用于此 DPS）可以提高我们对随时间推移的种群动态的理解，并允许我们估计种群状态的不同度量，相对（未捕捞的）产卵种群生物量（SSB），而不仅仅是 SPR。
