    Beschreibung: The spring session of ACFM gave advice for a numberof stocks in the North Atlantic, North Sea and Baltic.The present assessment of the situation is given here forstocks of higher importance for the German fishery.These are: Blue Whiting: the stock is still relatively high,this, however, will not last very long, due to too intensefishing. Cod in Kattegat: stock is outside safe biologicallimits. No immediate recovery in sight. Cod in 22–24(Baltic): stock is inside save biological limits. F, however, is above the recommendation of the IBSFC. GreenlandHalibut: state of the stock not quite clear. The presentfishing intensity seems to be sustainable. Herring (Atlanto-scandian, Norwegian spring spawner): stock is within safe biological limits, weak recruitment of the recent years will lead to a reduction of biomass. Herring: for Baltic spring spawner in 22–24 and IIIa still no increasing tendency detectable. North Sea Herring: furtherincreasing tendency, with 900 000 t over B lim, goodrecruitment. Herring in VIa: stable. Redfish: generallydecreasing tendency observed, a reduction of the fisheryis recommended. Signs of recovery, however, visible for some units

    Beschreibung: 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.

    Beschreibung: Information is given about the last meeting of the ICES “Herring Assessment Working Group for the Area South of 62° N”, conducted from 9.-18. March 1998 in Copenhagen. The actual stock development and the catch option estimations for different assessment units of herring and sprat are presented. The spawning stock size of North Sea herring was in 1997 still below the “Minimum Biological Acceptable Level” (MBAL) of 800 000 t. Keeping the fishing mortalities at the present level, the spawning stock size should reach a level of about 1.1 million tons by end of 1998. For the Western Baltic pring spawning herring stock no actual stock parameters were estimated. Due to uncertainties in splitting the catches in North sea autumn and Baltic spring spawners no analytical assessment was accepted.
