dc.description.abstract | An analysis is made on the blue whiting data from the echo surveys conducted
during 1972-1974 for assessment of the spawning stock west of the British Isles.
Acoustic data are evaluated using a length dependent density coefficient.
Area and time coverage are discussed for each survey. Mean density and total
abundance are calculated for the three years in the investigated area, and a stock size
of approximately 6 million tons is suggested for the spawning stock. | en |
