Aims, contents and method of the course

In this course, we analyse origin, quality and –energy content of food sources of different fish species in aquatic environments. We investigate feeding ecology of fishes, patterns of food selectivity and their relevance for consumption and production in single species as well as the consequences on the food webs (i.e. bottom up vs. top down effects, trophic cascades, etc.). We will analyse/observe
different fish species, macro-zoobenthos, zooplankton and algae.

Methods: Qualitative and quantitative stomach and gut analyses of fishes, stable isotopes, C/N element analyses, lipids and fatty acid analyses, compound-specific stable isotopes, multivariate analysis, mixing models
