Predator-prey dynamics of planktivorous fish – a spatial approach

Friday seminar by Geir Huse. (NOTE THE TIME AND VENUE!)

Abstract

Planktivorous fish play a central role in the trophodynamic structure and function of marine ecosystems. Due to the dynamic space use by planktivorous fish, one needs to capture their spatial distribution in order to understand their interactions with predators, prey and each other. In this presentation the focus will be on the Barents Sea capelin and the "pelagic complex" in the Norwegian Sea consisting of herring, mackerel and blue whiting and the roles that they have as predators and prey in their respective ecosystems. All these stocks perform substantial seasonal migrations and emphasis will be put on spatially explicit models developed for these stocks and the importance of spatial dynamics in predator prey interactions.
