Fishes respond to ecosystem change (e.g., climate change, species invasions or contaminants) in many ways, including changes in behaviour. Behavioural changes can alter growth rates, and therefore survival and spawning activity/success. Behavioural changes can also affect the likelihood of fish encountering fishing nets (termed catchability) that resource managers use to estimate population size (and allowable harvest). The research program of the Chair seeks to understand the role of fish behaviour and its adaptive role among fish populations facing ecosystem change, and to define relationships between fish behaviour and catchability so resource managers can improve fisheries population and harvest estimates.

鱼类以许多方式对生态系统变化（例如气候变化，物种入侵或污染物）做出反应，包括行为的变化。行为变化可以改变增长率，因此生存和产卵活动/成功。行为变化还会影响遇到鱼网遇到鱼网的可能性（称为捕获性），资源经理用来估计人口规模（和允许收获）。主席的研究计划试图了解鱼类行为的作用及其在面临生态系统变化的鱼类种群中的作用，并定义鱼类行为和捕捉性之间的关系，以便资源管理者可以改善渔业人群和收获估计。
