My research aims to assess and mitigate the impacts of fisheries on aquatic ecosystems; exploitation in aquatic food webs shifts the balance between schooling pelagic fishes and demersal fish, and hence affects the long-term sustainability of human fisheries. New approaches, methodologies and tools are employed as hypothesis testing engines. In particular my research focusses on how historical reconstruction of past ecosystem states provides quantitative long-term management goals and a template against which management options can be evaluated. The work employs several types of dynamic numerical ecosystem modelling, including spatial models, that allows tests of hypotheses about how fisheries alter the trophic structure, habitat, species diversity, keystone species and life history characteristics of organisms in aquatic ecosystems. This methodology makes it possible to carry out thought-experiments, since real ones are both impractical and

我的研究旨在评估和减轻渔业对水生生态系统的影响;水生食物网的开发改变了鱼群中中上层鱼类和底层鱼类之间的平衡，从而影响了人类渔业的长期可持续性。采用新的方法、方法和工具作为假设检验引擎。特别是我的研究集中在如何历史重建过去的生态系统状态提供定量的长期管理目标和管理方案可以评估的模板。这项工作采用了若干类型的动态数值生态系统模型，包括空间模型，从而可以检验关于渔业如何改变水生生态系统中生物的营养结构、生境、物种多样性、关键物种和生活史特征的假设。这种方法使得进行思想实验成为可能，因为真实的实验既不切实际，
