dc.description.abstract | In 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 |
