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 2012 year class strength of sand eel 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 validate/quality ensure each haul using bottom contact sensors mounted on the gear (dredges).

Dredge
On each sampling location three hauls were carried out with the modified mussel dredge according to descriptions for fishing with modified mussel dredge used since 2004. The DK IV dredge was used as the primary gear and the DK III dredge served as 'back-up'. 13.12.2012 no
DTUAQU Olesen Hans 99 samples G02
Grab
On new sample locations sediment samples were taken with the Van Veen grab (0.2m2), for the determination of grain size composition i.e. whether the bottom could be classi-fiedas a suitable habitat for sand eel (e.g. could a very fine-grained sediment be unfit as overwintering habitat).. 13.12.2012 no
