dc.description.abstractBoth the total and spawning stocks of North-East Arctic cod were assessed using Norwegian survey data and commercial landings. The total stock at 1 January was estimated to about 3250 million specimens, of which age group 1 and 2 amounted to about 2400 and 500 million specimens respectively whereas the older agegroups (3+) were estimated to 350 million specimens altogether. The last figure, 350 million, is somewhat higher than the estimate of about 275 million specimens arrived at by the Working Group on Arctic Fisheries. The spawning stock at 1 January 1984 was estimated to 87 million specimens which is a considerable reduction as compared to 1983. The bulk of the spawning stock were made up by 6, 7 and 8 years old fish.en
