Ziel der Reise / Objectives of Cruise:

Objective: International autumn acoustic survey for pelagic fish stocks in the Baltic Narrative: RV SOLEA left the port of Rostock-Marienehe on 4 October 2010. The acoustic equipment (echosounder EK60) was calibrated in the daytime on 5 October 2010 abeam Kuhlungsborn. The joint German-Danish acoustic survey covered the southern part of Subdivision 21 and the whole area of Subdivisions 22, 23 and 24. The northern part of Subdivision 21 could not be covered due to stormy weather. All investigations were done during night as in the years before. 57 trawl hauls were carried out to identify the target species. From each haul sub-samples were taken to determine length and weight of fish. Further samples of herring and sprat were frozen for additional investigations in the lab (sex, maturity, age). After each trawl haul the hydrographic conditions were recorded by CTD-O2 probe casts. The survey ended on the 22 October 2010 in Rostock-Marienehe.
