Audit of the use of productivity trends in fisheries advice

In many cases ICES incorporates ecosystem trends and variability into the fishing opportunities advice. However, there is no system to document when and how this is done. This results in the inclusion and incorporation of ecosystem trends and variability being generally invisible to the network and the outside community. From 2019 to 2022, ACOM worked with the expert groups that feed into fishing opportunities advice to audit the use of ecosystem trends and variability into the fishing opportunities advice. A questionnaire was used as the main tool. In 2020, each stock assessment working group was asked to record the ways in which ecosystem trends and variability are accounted for in each stock assessment, forecast, mixed fishery or management plan evaluation. This included considerations for short lived and data limited stocks. This is the data set that resulted from the questionnaire.

多数情况下，国际海洋考察理事会（ICES）会将生态系统趋势与变异性纳入捕捞机会建议的制定环节。但目前尚无配套系统可记录此类生态要素的纳入时机与具体实施方式。这导致生态系统趋势与变异性的纳入过程，对该专家网络及外部学界而言普遍缺乏透明度。2019年至2022年，ACOM与为捕捞机会建议提供技术支撑的专家工作组合作，对生态系统趋势与变异性在捕捞机会建议中的应用情况进行审核。本次审核以调查问卷作为核心实施工具。2020年，各资源评估（stock assessment）工作组被要求记录其在各项资源评估、渔业预报、混合渔业管理或管理计划评估中，考量生态系统趋势与变异性的具体方式，此项工作覆盖了短生命周期种群与数据受限种群的相关场景。本数据集正是基于该调查问卷所生成的最终成果。
