This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.

该项目旨在量化捕捞和气候变化对海洋鱼类和生态系统的累积影响。该项目希望通过将鱼耳骨中丰富的生物信息与有针对性的多代实验和预测建模相结合，在这一领域产生新的知识。预期的结果包括对人类引起的环境变化如何影响鱼类生长和成熟的基本见解，以及随后对渔业模型对这些生活史特征趋势的敏感性的关键评估。这将为渔业和生态系统管理带来重大利益，确保它们在环境迅速变化的时期保持生产力和复原力。
