This study comprises and compares epibenthic samples of the marine crustacean decapod megafauna, taken with a beam trawl at numerous stations in the German Exclusive Economic Zone of the North Sea in the years 1987, 1990, 2007 and 2013. All decapod crustacean species were recorded quantitatively. An overview of the decapod faunal composition with respect to changes in space, species and abundance with time is given. A time-dependent decrease of rare and often northern species at the research area is obvious, as a result of an increase of some dominant species concentrating in coastal areas. In 2013, a more uniform species composition seems to have developed. Decapod species and abundance depletions may be influenced by many factors, among them also climate change and fisheries.
The distribution of the larger epifauna during summer and winter in the North Sea and its suitability for environmental monitoring.
