Ziel der Reise / Objectives of Cruise:
Participation in the ICES co-ordinated 'International Bottom Trawl Survey' 2006, 1st quarter in the North Sea. The objective of the survey is to estimate the strength of the upcoming year classes of the demersal fish species cod, haddock, whiting and Norway Pout as well as of the pelagic species herring, sprat and mackerel. In addition, the distribution and abundance of herring larvae are to be investigated. Temperature, salinity, and nutrients in the area of investigation are monitored. According to the international ICES program coordinated by the Netherlands (RIVO-DLO) the rectangles assigned to Germany in the northern and central North Sea were to be fished by means of the ICES standard bottom trawl GOV during daytime and by the pelagic herring larvae net MIK during night. Additionally, temperature and salinity measurements and nutrient samples were to be taken in each rectangle. Due to the good weather conditions, WALTHER HERWIG was able to complete 70 of the 75 assigned statistical rectangles. In total, WALTHER HERWIG carried out 140 MIK and 70 GOV hauls as well as 70 CTD profiles.
