Observations on the Cod and Cod Fisheries of Lofoten
(ICES CM Documents;1953/36, Working paper, 1953) -
Observations on the Depth Range of tagged Bluefin Tuna (Thunnus thynnus L.) based on Pressure Marks on the Lea Tag
(ICES CM Documents, Working paper, 1964)The present paper is an investigation on the depth range of tagged bluefin tuna based on pressure marks on the Lea tag (Figure 1). It was observed that the within season recaptures were without pressure marks, while the ... -
Observations on the spawning grounds of the North Sea and Norway coast stocks of saithe
(ICES CM Documents;1974/F:44, Working paper, 1974) -
Observed avoidance behaviour in herring in relation to passage of an echo survey vessel.
(ICES CM Documents;1979/B:18, Working paper, 1979) -
Observer program for juvenile Northeast Arctic saithe
(Working paper, 2002) -
Observer program for juvenile Northeast Arctic saithe
(Working paper, 2010-02)NEA saithe 0-group indices from observers along the coast does not seem to reflect the dynamics in year class strength very well and is therefore probably not suitable for improving future recruitment estimates for this stock. -
Observer program for juvenile Northeast Arctic saithe: Status report
(Working paper, 2007) -
Observing behaviour of over-wintering Herring (Clupea harrengus L.) in Ofoten with Acoustic Current profiler
(ICES CM Documents;2003/Q:6, Working paper, 2003)In this paper we present results and interpretation of velocity and signal strength data collected with a ‘Continental’ Current Profiler on over-wintering herring in the Ofoten in the North of Norway. The instrument was ... -
Occurence and structure of cysts in x-cell lesions of Atlantic cod (Gadus morhua L.)
(ICES CM Documents;1994/E:12, Working paper, 1994)Introduction: Despite numerous investigations the nature and origin of x -cells remain unknown. These ovoid, pale-staining cells with a large, round nucleus and prominent nucleolus are known to occur in the form of ... -
Occurence of blue whiting in trawl catches during surveys from Portugal to Faroe Islands, 1979- 1995
(ICES CM Documents;1996/S:30, Working paper, 1996)Historical data on blue whiting (Micromesistius poutassou) from survey trawl stations of 7 countries, have been congregated and prepared into special files, together with corresponding temperature and salinity observations. ... -
Ocean pathways in the Arctic
(ICES CM Documents;1997/R:8, Working paper, 1997)Introduction: The Arctic Monitoring and Assessment Programme (AMAP), established in 1991, was given the responsibility to monitor the levels and assess the effects of selected anthropogenic pollutants in all compartments ... -
Oil exploration in new offshore fields. Fish larvae as the critical component in the assessment of potential consequenses for the fish resources
(ICES CM Documents;1988/E:18, Working paper, 1988)The effects of oil and other pollutants on fish larvae are depending both on species and age/weight/length of the larvae. Critical factors in an assessment of consequenses of oil activities on fish resources are both ... -
Oil production structures in the North Sea as fish aggregating devices
(ICES CM documents, Working paper, 1998)The paper deals with a study aimed at investigating whether underwater structures from decommissioned oil platforms in the North Sea can be used as artificial fish reefs or protection habitats for fish. The experimental ... -
Oil-tainting of fish, a laboratory test on salmon and saithe
(ICES CM Documents;1976/E:33, Working paper, 1976) -
Old and new perspectives on zooplankton and vertical particle flux
(ICES CM Documents;1996/O:10, Working paper, 1996)Our understanding of the relationships between zooplankton and vertical flux of particles in the North Atlantic has matured over the last half century. Evolving from the simple concept of 11 grazing inhibits sedimentation", ... -
On acoustic identification, sizing and abundance estimation of fish
(ICES CM documents, Working paper, 1970) -
On acoustic multi-frequency species identification and separation of Atlantic mackerel, Norwegian spring spawn herring and Norway pout.
(ICES CM documents, Working paper, 2004)The accuracy of the multi-frequency species identification and separation algorithms may be significantly improved when the detailed acoustic scattering characteristics of the fish are known, including its expected variability ... -

On fecundity of North Sea mackerel (Scomber scombrus)
(ICES CM Documents;1980/H:47, Working paper, 1980)This paper presents a preliminary analysis of the fecundity-length relationship of the North Sea mackerel. The relationship was compared to that of the Western mackerel stock (LOCKWOOD,1978) by an analysis of covariance ... -
