Ziel der Reise / Objectives of Cruise:

International acoustic survey for pelagic fish stocks in the North Sea. Narrative: RV 'SOLEA' left the port of Cuxhaven on 25th June 2010. The survey covered the southern part of the North Sea. All investigations were done during day time from 0400UTC - 1800UTC. The acoustic equipment was an echosounder EK60 with the hull mounted transducer ES38B and ES120-7. 41 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 used for additional investigations (i.e. sex, maturity, age). On 62 stations temperature and salinity were recorded by a SBE CTD probe. The survey ended on 13th July 2010 in the morning. RV 'SOLEA' entered the port of Cuxhaven the same day. An extended cruise report giving age disaggregated abundance and biomass of clupeids and detailed hydrographical data will be available after final data and sample evaluation at the end of this year. This report will be delivered to and published by the ICES Planning Group for Herring Surveys in the beginning of 2011.
