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 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 ICES WGEEL since 2023.



2020: PhD in Marine Ecology, Swedish University of Agricultural Sciences (SLU): "Size-dependent predator-prey interactions, distribution and mortality in salmon: effects on individuals and populations"

2015: MSc degree in Marine Ecology, Stockholm University, Sweden.

2013: BSc degree in Biology, Stockholm University, Sweden.


Ongoing: Main supervisor for Emil Rask, independent project, 15 credit bachelor level: A study of cormorant predation on eel.

Ongoing: Co-supervisor for Elin Sjögren, 60 credit MSc project: Constraints in the upstream migration of the European eel.

2024: Main supervisor for Ellen Schaal, independent project, 15 credit bachelor level: The variability of habitat use by the European eel (Anguilla anguilla) during its resident yellow eel life stage throughout its distribution range.

2018-2019: Co-supervisor for Ulrika Tollerz Brattby, 30 credit MSc thesis project: Factors explaining variation in the fecundity of female Baltic salmon (Salmo salar) – the influence of length, body condition and growth rate at sea.
