Marine heatwaves (MHWs, https://en.wikipedia.org/wiki/Marine_heatwave) are occurring more frequently and with an increasing intensity. Improving our understanding of the consequences of MHWs on marine life is imperative for conservation and management. In particular, for fish, large global data sets (https://www.ramlegacy.org, https://www.fishbase.se, https://www.ices.dk/data/data-portals/Pages/DATRAS.aspx) are available for empirical analysis. Combining these data sets with a mechanistic understanding of how heatwaves may affect the early life of fish (https://ladim.readthedocs.io/en/master/intro.html) will be a key step forward. Moreover, the outcome of MHWs will depend on the fish population’s state, e.g., population size and age structure. The population size and the age structure are to a large extent affected by harvesting levels. This theme will use a modeling approach where different data sources can be combined. The main aim will be to address how harvesting and climate change will affect fish populations across the globe.
