Climate-enhanced stock assessment models represent potentially vital tools for managing living marine resources under climate change. We present a climate-enhanced stock assessment where environmental variables are integrated within a population dynamics model assessment of biomass, fishing mortality and recruitment that also accounts for process error in demographic parameters. Probability distributions for the impact of the associated environmental factors on recruitment and growth can either be obtained from Bayesian analyses that involve fitting the population dynamics model to the available data or from auxiliary analyses. The results of the assessment form the basis for the calculation of biological and economic target and limit reference points, and projections under alternative harvest strategies. The approach is applied to northern rock sole (Lepidopsetta polyxystra), an important component of the flatfish fisheries in the Eastern Bering Sea. The assessment involves fitting to data on catches, a survey index of abundance, fishery and survey age-compositions and survey weight-at-age, with the relationship between recruitment and cold pool extent and that between growth increment in weight and temperature integrated into the assessment. The projections also allow for an impact of ocean pH on expected recruitment based on auxiliary analyses. Several alternative models are explored to assess the consequences of different ways to model environmental impacts on population demography. The estimates of historical biomass, recruitment and fishing mortality for northern rock sole are not markedly impacted by including climate and environmental factors, but estimates of target and limit reference points are sensitive to whether and how environmental variables are included in stock assessments and projections.

气候增强的种群评估模型代表了在气候变化下管理海洋生物资源的潜在重要工具。我们提出了气候增强的种群评估，其中环境变量被整合到生物量、捕捞死亡率和补充的种群动态模型评估中，这也解释了人口参数中的过程错误。相关环境因素对招募和增长的影响的概率分布可以从贝叶斯分析中获得，贝叶斯分析涉及将人口动态模型与可用数据进行拟合，也可以从辅助分析中获得。评估结果构成了计算生物和经济目标和限制参考点以及替代收获策略下的预测的基础。多鳞鳞翅目)，白令海东部比目鱼渔业的重要组成部分。评估包括拟合渔获量数据、丰度调查指数、渔业和调查年龄组成和调查年龄体重，将补充与冷池范围之间的关系以及体重增长与温度之间的关系整合到评估。预测还考虑到海洋 pH 值对基于辅助分析的预期补充的影响。探索了几种替代模型，以评估模拟环境对人口统计的影响的不同方法的后果。对北岩鳎历史生物量、补充和捕捞死亡率的估计不受气候和环境因素的显着影响，
