In the period 24 February to 14 March 1975 three echo surveys were made with R. V. "Peder Rønnestad" in the Lofoten area. The distribution of the spawning Arctic cod was charted by counting the number of fish recorded per nautical mile by the echo sounder. The spawning in 1975 occurred relatively late, probably because of low sea temperatures. Purse line catches indicate that the spawning population is still to a considerable extent composed of older fish
