dc.description.abstractIn March/April 1995 the fifth Norwegian-Russian joint acoustic survey on the blue whiting spawning stock was carried out. The shelf edge area to the west of The British Isles was covered by two vessels in a general south-north direction. A ship-to-ship calibration of the acoustic instruments justified a 1:1 relationship between the vessels when combining the acoustic data. The biomass of the observed blue whiting stock within the area surveyed was estimated to 6.9 mill. tonnes. Of this, the spawning stock constituted 6.1 mill. tonnes. The 1994 year class was found to be the richest one contributing with 27% in numbers. As the survey also was part of the SEFOS programme, plankton stations were carried out throughout the whole area for studies of blue whiting eggs and larvae. The hydrographic situation in the surveyed area was similar to the one observed in 1993.no_NO
