A brief report is given on the result from an acoustic survey
with the R/V "Michael Sars'' to the blue whiting spawning area
in second half of April 1979.
Rather dense concentrations of blue whiting were found from
west of Scotland to the Faroes. Length- and age- composition
are given. The majority of the stock consisted of 3 - 8 year
old fish. Length-weight relationship is found to be different
from previous years, and half of the stock was either ripe or
spent.
A rough and preliminary figure of 4 mill. tonnes was calculated.
