                        <gco:CharacterString>Im Sommer 1991 wurde an der niedersächsischen Küste ein starker Brutfall der Miesmuschel (Mytilus edulis) festgestellt.
Der vorliegende Bericht dokumentiert den Verlauf einer ca. 0,3 km² großen Neuansiedlung im Inselwatt von Norderney über den Zeitraum eines Jahres. Neben der Entwicklung der Muscheln wurden auch die Veränderungen der Begleitfauna und des Sedimentes beobachtet.
Die zunächst offensichtlich guten Voraussetzungen ermöglichten stetiges Wachstum und den typischen Aufbau einer Schlickschicht vom Zeitpunkt der ersten Beprobung im Juli 1991 bis zum September desselben Jahres. In der nachfolgenden Winterpause beeinträchtigen Starkwindlagen und Eisgang Siedlungsstruktur und Abundanz. Für die übrig gebliebenen Tiere haben sich die Bedingungen auf dem inzwischen wieder nahezu schlickfreien Sediment offenbar derart verschlechtert, daß in der folgenden Zeit nur noch ein steter Rückgang zu verzeichnen ist. Im Juli des Jahres 1992 sind nur noch spärliche Reste vorhanden, die bis zum Ende des Jahres ebenfalls verschwunden sind.
 During the summer 1991 an intensive spat fall of blue mussels happened along the Lower Saxonian coast. This paper describes the development of a new mussel bed in the tidal flats of Norderney that covered an area of approximately 0.3 km2. Changes of correlated fauna and sediment were also investigated. The first sampling took place in July 1991. Until September circumstances were obviously very good to allow a constant growth of mussels, correlated with the typical increase of a silt layer. During the following months the development stagnated and strong wind and floating ice had a disastrous impact on the structure and abundances of the mussel bed. The silt layer had almost disappeared and a continuous decline of mussels was registered. In July 1992 only few mussels were left and were finally lost completely by the end of the year.</gco:CharacterString>
