Trawl and acoustic survey for herring stocks, complex oceanographic survey of the Norwegian Sea to develop the long-term cooperation within ICES.
Fish distribution will be investigated with acoustic devices. Check tows will be made by a mid-water trawl with a minimum mesh size of 16mm in the bag. Oceanographic observations including water temperature and salinity measurements as well as hydro chemical investigations will be carried out at stations of standard oceanographic sections and at trawl stations. Plankton sampling will be made with Juday plankton.
