Acoustic estimates of spawning cod off Lofoten and Møre in 1985
The annual surveys on the spawning stock of North-east Arctic cod were carried out in the Lofoten and Møre areas in March- April 1985. These surveys were undertaken to estimate the size and age structure of the spawning cod on the main spawning grounds. The area used in the estimation this year is s...
