    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.
