Ziel der Reise / Objectives of Cruise:
The purpose of the sand eel dredge survey was to collect sand eels buried in the seabed and compare catches (number and age composition) with the previous year's collections to assess the 2010 year class strength of the lesser sand eel (Ammodytes marinus) in the different areas adopted by ICES in 2009. Data from the dredge survey is the basis for calculating a 0-group index, which will be used in stock assessment. In addition, it was the aim to test an underwater video module mounted on the dredge, as well as try to validate/quality ensure each haul using bottom contact sensors mounted on the gear (dredges). Furthermore, to identify any practical problems connected with the collection of quantita-tive samples during the survey. The vessel departed Thyboron harbor 22.11.2010 at 14.00 hrs. and arrived Thyboron harbor 4.12.2010 at 00.30 hrs. Sampling with the dredge typically started just after sun set (UTC 17.00 hrs) and the last station of the night was completed before sunrise (UTC 04.00 - 06.00 hrs) i.e. fishing was only conducted during darkness.
