BIO-3516 Food-webs and fisheries - 10 stp

The course is administrated by

Faculty of Biosciences, Fisheries and Economics

Type of course

Master course for biology students and master students in fishery science. The course is available as a singular course 

Course contents

The course deals with how food-web models can be used to analyse topics of interest for fishery and ecosystem management. Lessons will give an overview of approaches and models used in fisheries management with emphasis on multispecies models. Local, regional and global perspectives on model strategies will be presented. We will describe principles regarding ecosystem services and resilience of ecosystems. In the course, we will use a food-web model system, Ecopath with Ecosim and Ecospace (EwE) and present the model principles. The students will learn guidance principles on how to incorporate information on input data and parameters to EwE, as well as  principles for parametrising dynamic models and analyse and report uncertainty. 

In data lab exercises, we will apply EwE with hands-on training and construct food-web models. "Snap-shot" Ecopath models will be converted to dynamic models and fitted to observed time-series of biomasses and catches and forced by biological and physical variables. Exercises also include using a spatial module, Ecospace, targeting analysis of spatial effects of management actions such as Marine protected areas. 

In a supervised term paper project, a quantitative objective will be analysed using a model ending with a written report and an oral presentation.
