Ziel der Reise / Objectives of Cruise:

Objective: International acoustic survey for pelagic fish stocks in the Baltic Narrative: The acoustic equipment (echosounder EK60) was calibrated before the start of the survey on 5th October 2005 south of Isle of Moen. RV 'SOLEA' left Rostock-Warnemunde on 6th September 2005. The joint German-Danish acoustic survey covered the whole Sub-divisions 21, 22, 23 and 24. All investigations were done during night. 51 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 (e.g. sex, maturity, age). After each trawl haul the hydrographic condition was recorded with a CTP-O2 probe. The survey ended 21st of October 2005 during early morning. RV 'SOLEA' entered the port of Rostock-Marienehe the same day.
