The EU Common Fisheries Policy (CFP) is reviewed and reformed every ten years. Before the latest reform, analysis of the current CFP showed that it was not very successful. Thus, in 2015, fundamental changes entered into force: Management targets were set bindingly, discards of unintended catches were largely prohibited and the new rules were regionally adapted. We analyse data series on catch composition, on the economic situation of fisheries and on the behaviour of individual fishermen. Based on these analyses, a major focus of our research work ahead will be to derive which elements the new regulations should contain to implement the reform successfully until 2020.
