 Bottom trawling has a direct impact on the targeted species, as well as physical disturbance of the seabed and the benthic invertebrate communities. This, in turn, affects benthiverse fish and the entire benthic food web structure and functioning. Predictions about the cascading effects of bottom trawling on benthic and demersal fish communities are important for understanding how they interact. In order to do this, it is necessary to understand the trophic interactions between benthic and demersal fish and benthic invertebrates. We assess the diets of benthic and demersal fish and the structure and functioning of the benthic food web in two areas in the German Baltic Sea, the Femrenbelt and the Oderbank. The Femrenbelt-Benthic invertebrate community is characterized by a high number of species and biomass, while the one on the Oderbank is species poor with high individual abundance, but low biomass. We used mixing models based on stable isotopes of carbon and nitrogen, combined with stomach content analyses, to estimate the.
