FISHBUDGET at a Glance

Global climate change effects are one of the greatest environmental challenge and are expected to worsen over the next decades. Such effects will deeply affect the physiological responses of marine organisms, namely, their growth, feed intake rates, metabolism, behaviour and activity, all of which likely compromising species' fitness and survival. Hence,  the overall objective of this 3-year research project is to evaluate, for the first time, the potential effects of climate change impacts on the energy budgets of temperate (e.g. Diplodus sargus and Solea senegalensis) and subtropical/tropical (e.g. Diplodus cervinus and Zebrasoma scopas) fish species during their juvenile stage. To do so, different components of the energy budget equation will be determined, namely growth (Task 2),  faecal and nitrogenous expenditures (Task 3), and respiration (Task 4). Finally, a model using a Dynamic Energy Budget (DEB) approach will be developed and implemented in order to understand the energy gain and losses, as well as to determine which environmental parameters are more likely to affect fish energy budget (Task 5). FISHBUDGET will allow to gather new insights on marine ecosystem functioning in tomorrow's ocean.
