Abstract
Throughout human existence we have relied on the oceans as they provide multiple ecosystem services, including food provision through fishing. This has led to overutilisation and therewith depletion of fish stocks. As a reaction there has been a surge in Marine Protected Areas (MPA) in the past century. In Europe, most MPA’s are part of the Natura 2000 (N2000) network. Their protection levels tend to vary between minimal to high protection, meaning that in many areas certain levels of extractions are allowed. In the Netherlands shrimp trawling happens more frequently inside N2000 areas, compared to outside. In this essay the aim is to research what the impact is of shrimp trawling on Dutch N2000 areas, based on current literature. The focus will be on the impacts on specific habitat types and therewith N2000 management goals. There are theories and models about positive indirect impacts of trawling when looking at ecological interactions or specific species, yet most studies tend to focus on the (direct) negative impacts. Some of which are a mortality in benthic invertebrate, leading to reduced benthic species richness, and reduced functioning of the benthic community. Most impacts depend on trawling gear and habitat type. In Dutch N2000 areas the focus is on improving and/or maintaining specific habitat types in combination with increasing endangered species abundance or boosting their habitat quality.
