Acoustic estimates of spawning cod off Lofoten and Møre in 1982
Nakken, Odd; Godø, Olav Rune; Raknes, Askjell (ICES CM documents, Working paper, 1982)Acoustic surveys on spawning cod were carried out in Lofoten and off Møre in order to estimate the stock size and structure. The 1975 yearclass made up the bulk of the spawning stock in both areas. In the Lofoten area the ... -

Corrections of indices of abundance of 0-group fish in the Barents Sea for varying capture efficiency
Nakken, Odd; Raknes, Askjell (ICES CM documents, Working paper, 1996)Each year since 1965 "The International 0-group Survey in the Barents Sea and Adjacent Waters" has provided indices of abundance of 0-group fish. During the 30 years of operation of the survey large improvements in capture ... -
On the geographical distribution of arctic cod in relation to the distribution of bottom temperatures in the Barents Sea, 1977-1984
Nakken, Odd; Raknes, Askjell (ICES CM documents, Working paper, 1984)The results from acoustic-trawl surveys in January-March were analysed together with observations of bottom temperatures at the same cruises. Distributions of fish abundance for each age group of cod on temperature were ... -
