Zustand der Herings- und Sprottenbestände in Nord- und Ostsee, östlichem Kanal und westlichen britischen Gewässern. Beurteilung durch die Herings- und Ostsee-Arbeitsgruppe des ICES, März/April 1999
Information is given about the results of the latest meeting of the Herring Assessment Working Group for the Area South of 62° N and the Baltic Fisheries Assessment Working Group, which were conducted in March and April at ICES headquarters in Copenhagen. The actual stock development and the catch options estimated for different assessment units of herring and sprat are presented. The spawning stock size of North Sea herring reached in 1998 for the first time since 1991 a level above the Minimum Biological Acceptable Level (MBAL) of 800 000 t. Keeping the fishery at the present level the spawning stock size should reach in 1999 a level of about 1.2 mio. t. For the Western Baltic Spring spawning herring stock no actual stock estimate was presented. Due to uncertainties in splitting the catches in North Sea autumn and Baltic spring spawners no analytical assessment was accepted.
