1. To conduct an acoustic survey to estimate the abundance and distribution of herring in the northwestern North Sea and north of Scotland between 58º30’-62ºN and from the shelf edge to 2ºE, excluding Faroese waters.
2. To obtain biological samples by trawling to confirm echosounder trace identification.
3. To obtain samples of herring and sprat for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection throughout the survey area.
4. Collect tissue samples and data for stock identity determination. Tissue samples for genetic analysis will be collected from herring throughout the survey area.
5. To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring and sprat.


All fishing gear and scientific equipment will be loaded onto the vessel on 3 July in Aberdeen. The vessel will depart from Aberdeen on 6 July and after required vessel drills, make passage to the start of the first transect to begin surveying. Crew training and trial deployments of fishing gear will take place on the way if required by the fishing master. The vessel will follow a pattern of parallel transects running east/west, at normal steaming speed (10.5 knots), progressing northwards. The whole survey area is bounded by 58º30'-62ºN and 02ºE to the 200 m contour. Transect spacing is 15 nm. This may be adapted during the survey to maximize area coverage given the time available.
