Sammanfattning
The Baltic species live on the edge of their tolerance limits. They face environmental challenges, such as temperature and salinity gradients, large hypoxic/anoxic regions, and also human induced eutrophication and high fishing pressure. In my PhD project I want to understand the predator-prey interactions between cod, herring and sprat in the Baltic Sea and how they are framed by a combination of processes: fishing exploitation, climate variability and density dependence. I will address this question with the help of multi-species modelling. Knowledge of study species and system is required to build a good model. This essay covers information on biology of cod, herring and sprat, interaction between them and environment challenges they face. Previous approaches used in studying predator-prey interactions in Baltic are reviewed and analysed.
