The third joint acoustic survey by research vesseles from IMR, Bergen
and PINRO, Murmansk, on blue whiting in the spawning area was carried
out in the period 17 March - 12 April 1992. The continental slope area
west of The British Isles was surveyed in south-north direction by one
vessel and in north-south direction at the same time by the other
vessel. A ship-to-ship calibration of the acoustic instruments was
performed in the mid-area, and the results used as basis for combination
of the data collected. The geographical distribution of the stock
was obtained for two different periods and hence the northward
migration of post-spawners illustrated.
