    Description: Seit der letzten speziellen Situationsbeschreibung des Kabeljaubestandes in dieser Zeitschrift sind 4 Jahre vergangen (EHRICH, 1988). In der Zwischenzeit ist besonders den Fischern durch weitere Fangeinbußen bewußt geworden, daß sich der Zustand des Bestandes nicht verbessert, sondern im Gegenteil weiter verschlechtert hat. Die Schonmaßnahmen wie stufenweise Erhöhung der vorgeschriebenenMindestmaschenweite auf 100 mmm und eine Reduzierung des Fischereiaufwandes in den Jahren 1991 und 1992 auf 70 % des Aufwandes in 1989 (Mindesthafenliegezeit: durchgehend 8 Tage pro Monat oder alternativ Erhöhung der Mindestmaschenweite auf 110 mm für die direkte Fischerei auf Kabeljau und Schellfisch) haben keine positive Wirkung gezeigt.

    Description: Die Größe der Fischbestände in der Nordsee unterliegt Schwankungen, die durch sich verändernde Faktoren ihrer Umwelt hervorgerufen werden. Diese Faktoren sind natürlichen (Klima, Nahrungsangebot) wie auch anthropogenen Ursprungs (Fischerei, Verschmutzung).

    Description: The pressure of users other than shipping and fishery on the national EEZs for territorial claims has increased in recent years. So it becomes necessary to carry out a spatial planning for which all users have to indicate their recent and planned future activities. For the German waters in the North Sea a first attempt was made to calculate the mean international landings for the commercially important fish and crustacean species on the spatial scale of ICES-rectangles. The relationships between the German and international landings per species are listed in a table and the distribution of the landings for each species within the area are shown in 13 figures.
