Acoustic applications in fisheries science: The ICES contribution
Fernandes, Paul G.; Gerlotto, Francois; Holliday, D. Vance; Nakken, Odd; Simmonds, E. John (ICES Marine Science Symposia, Conference object, 2002) -
Acoustic estimates of 0-group fish abundance in the Barents Sea and adjacent waters in 1992 and 1993
Nakken, Odd; Hylen, Arvid; Ona, Egil (PINRO-IMR Symposium, Conference object, 1995)Acoustic and biological data collected during the international O-group surveys in 1992 and 1993 were used to estimate the abundance of O-group fish of 4 species; cod, haddock, redfish and polar cod. The abundances of ... -
Acoustic estimates of spawning cod in the Lofoten area in 1982 and 1983
Nakken, Odd (PINRO-IMR Symposium, Conference object, 1984)The main spawning grounds for Arctic cod, the Lofoten area, were covered by acoustic surveys 7 times in 1983 and 12 times in 1983 during the prespawning and spawning season. The results indicated a spawning stock in the ... -
Causes of trends and fluctuations in the Arcto-Norwegian stock
Nakken, Odd (ICES Marine Science Symposia, Conference object, 1994)Published information is used to review trends and fluctuations in landings and stock characteristics/variables (abundance, growth, maturation, distribution, and migrations) in relation to changes in environmental and ... -
Comparison of the capture efficiency of 0-group fish in pelagic trawls
Hylen, Arvid; Korsbrekke, Knut; Nakken, Odd; Ona, Egil (PINRO-IMR Symposium, Conference object, 1995)In 1992 and 1993 experiments were carried out during the international 0-group fish surveys in order to study the capture efficiency of two pelagic trawls. The catches of the standard sampling trawl were compared with ... -

Retrospective review of management advice and TAC's for some stocks
Nakken, Odd (IMR/PINRO Joint Report Series, Conference object, 2002)During the part 20 years fisheries management in the Barents Sea and adjacent waters has been based on annual advice provided by The International Council for the Exploration of the Sea, ICES. In the present paper the ... -
Retrospective review of management advice for Northeast Arctic cod [presentation]
Aglen, Asgeir; Nakken, Odd; Yaragina, Natalia A.; Sokolov, Konstantin (IMR/PINRO Joint Report Series;2/2005, Conference object, 2005) -
Retrospective review of management advice for the northeast Arctic cod

Understanding environmental control on fish stocks and progress toward their inclusion in fish stock assessment
Nakken, Odd (ICES Marine Science Symposia, Conference object, 2002)The need to understand the impact of the environment on the fluctuations in fisheries yield in the Northeast Atlantic was a major motivation for the creation of ICES. From the very beginning, two main research tasks were ...
