Original versionThis report is not to be quoted without prior consultation with the General Secretary.
Both 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 1985 was estimated to about 5100 million specimens, of which age group 2 and 3 amounted to about 3400 and 1200 million specimens respectively. The total number of fish of age 3 and older (3+) were estimated to 1500 million specimens which is 2.5 times higher than the estimate of about 575 million specimens arrived at by the Working Group on Arctic Fisheries. The spawning stock at 1 January 1985 was estimated to 72 million specimens which is a 17 percent reduction as compared to 1984. The bulk of the spawning stock were made up by 5, 6, 7 and 8 years old fish.
