This paper summarises the detailed information on catch, fork length, weight, sex and maturity of alfonsinos Beryx splendens and Beryx decadactylus collected from targeted surveys in Azores waters, complemented by fishery data, over the past c. 20 years. To date, it was not possible to define if the Azorean component of the population can be considered as a discrete local management unit. The reason for this is the lack of available information for these resources covering the entire spatial distribution of the species in the North Atlantic Ocean. Additionally, there are some conflicts between the different genetic results available, poor understanding about the species movements and data from the Azores show some discrepancies in aspects of reproduction. Consequently, there is no analytical assessment for this resource and the stock of Beryx spp. is currently managed based on the precautionary approach. Outputs of recent analyses are presented in this study and possible assumptions and strategies for the assessment are discussed.
本文总结了过去约20年里从亚速尔群岛海域的目标调查中收集到的关于红金眼鲷（Beryx splendens）和十棘金眼鲷（Beryx decadactylus）的渔获量、叉长、体重、性别和成熟度的详细信息，并辅以渔业数据。迄今为止，尚无法确定该种群在亚速尔群岛的部分是否可被视为一个独立的地方管理单元。原因在于缺乏涵盖该物种在北大西洋整个空间分布的这些资源的可用信息。此外，现有不同的遗传结果之间存在一些冲突，对该物种的洄游了解不足，且来自亚速尔群岛的数据在繁殖方面存在一些差异。因此，目前没有对该资源进行分析评估，红金眼鲷属鱼类种群目前是基于预防性方法进行管理的。本研究展示了近期分析的结果，并讨论了评估的可能假设和策略。
