Philip Jacobson

My research focus on the importance of predator-prey interactions for individual performance and population dynamics of predatory fish and their ecological function in aquatic systems. I further work with and scientifically evaluate the Swedish national data collection program for European eel within the unit of diadromous fish at SLU Aqua since 2022. I am also a memeber of the international working group for eel, WGEEL, since 2023.
