Summary: | 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. |
