Description
Summary:Acoustic surveys on northeast Arctic spawning cod were carried out in Lofoten and off Møre in March-April 1984 in order to estimate the stock size and structure. Within the investigated areas the total number at spawning cod was estimated to about 40 million specimens. This was a reduction of 25-30 percent as compared to the results in 1983 when a total of 56 million specimens was estimated within the same areas. Particularly in the Møre area spawning cod was far less abundant in 1984 than in 1983.
