Sampling is carried out at fixed positions on known sand ell habitats at some of the most important fishing banks in the North Sea from the little Fisher Bank in the North

* To sample the zooplankton population associated with the Dogger Bank chlorophyll maximum and measure associated grazing rates and 2o production.. The cruise was undertaken

Based on the single fish sampled in each haul for micro-structure analysis of the otolith the maturity by age key was made for both North Sea herring and Western Baltic herring as

In total 40 trawl hauls with the GOV-trawl were carried out, 40 CTD –profiles were taken, 80 MIK-trawl hauls and 2 MIK-trawl hauls for calibration of flow- meters were taken.

In connection with the acoustic monitoring of the Norwegian Spring Spawning herring and the blue whiting in the Norwegian Sea, calibration of the acoustic equipment
