Understanding climate and harvest induced changes in fish life histories
Grant number: DP190101627 | Funding period: 2019 - 2022
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 o..View full description
