Abstract

Management of anadromous salmon stocks is usually based on an estimate of the spawner-recruitment relationship. A wide variety of estimation approaches have been developed, from simple to complex, and some worthwhile methodologies and auxiliary data are underutilized. The types and quality of the data available determine the most appropriate assessment methodology and the reliability of the assessment results. The management strategies available and the performance of these strategies are likewise highly dependent on the available data. This review gives an overview of the range of assessment methodologies, from the ad-hoc to hierarchical Bayesian state-space approaches. It emphasizes the central role of data; data types, data deficiencies, auxiliary information such as environmental indices, habitat characteristics, and similar stocks, and the effects of the data on the quality of guidance to managers.

摘要

溯河鲑鱼群的管理通常基于对产卵者-招募关系的估计。已经开发了各种各样的估计方法，从简单到复杂，一些有价值的方法和辅助数据没有得到充分利用。可用数据的类型和质量决定了最合适的评估方法和评估结果的可靠性。可用的管理策略和这些策略的性能同样高度依赖于可用数据。本综述概述了评估方法的范围，从临时到分层贝叶斯状态空间方法。它强调数据的核心作用；数据类型、数据缺陷、环境指数、栖息地特征和类似种群等辅助信息，
