We provide a state-dependent energy allocation model to assess the impacts of climate warming on the life-history evolution and behaviour of Atlantic cod, specifically the North-East Arctic stock (NEA). Model predictions show the response is positive for this stock, individuals grow quicker and are more fecund, exhibiting increased foraging behaviour. We reveal the underlying mechanisms and drivers of change in NEA cod, which has important implications for conservation physiology.
