Abstract

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.
