international beam trawl survey and monitoring of benthic fauna in the configured FFH areas. The international beam trawl survey of the International Council for the Exploration of the Sea (ICES) is held once every year with the participation of Holland, Belgium, England and Germany held and covers the area of the Irish Sea, the English Channel and the central North Sea. The spectrum of species recorded here differs considerably from the clutches of using otter trawls from, so this series is a complement to the other bottom trawl surveys. In particular, smaller flatfish are well recognized, but smaller round-dwelling fishes and larger invertebrates such as sea urchins, whelks and sea stars. Flatfish and the entire ground-level fauna have moved to the interest because of the potential damage caused by the intense beam trawling. The results are fed into a common database and published annually in the form of distribution maps and density indices for the most common types. The configured FFH areas Borkum Reef, Dogger Bank and Sylt Outer Reef are sampled with respect to their fish fauna in seven years with the beam trawl.
