Description:
From January 22 to February 12, 1993, "Walther Herwig" participated in the ICES coordinated International Bottom Trawl Survey (IBTS, formerly International Young FishSurvey (IYFS)) in the North Sea. In total all participating nations covered 369 fishing stations, 65 of which were investigated by "Walther Herwig". Preliminary results show that the youngest yearclasses of haddock, whiting, sprat and Norway pout are well above average whereas herring in his second year of life is only average. No signs of a recovery of the North Sea mackerel stock could be detected. The measured temperature data show a more or less mean situation during the period under review.
