Initial collateral measurements of some properties of Calanus finmarchicus
(ICES CM Documents;1996/L:21, Working paper, 1996)In general, acoustic quantification of zooplankton such as Calanus finmarchicus requires the use of models, among other reasons, to aid in the interpretations of data collected on animals whose scattering properties change ... -
Joint Report of the Working Group on Marine Mammal Habitats and the Working Group on Marine Mammal Population Dynamics and Trophic Interactions [Helsinki, Finland, 28 February - 3 March, 2000]

Local spatial heterogeneity in blue whiting length structure
(ICES CM documents;2007/Q:16, Working paper, 2007)We have used “MultiSampler”, a multiple opening-closing device that allows obtaining several samples from a single trawl haul, during the trawl-acoustic survey targeting blue whiting (Micromesistius poutassou) on their ... -
Near-bottom sampling with bottom and pelagic trawls
(ICES CM Documents;1987/B:15, Working paper, 1987)The Institute of Marine Research, Bergen, has carried out combined bottom trawl and acoustic surveys for cod and haddock in the Barents Sea - Svalbard area since 1981. These investigations have demonstrated clearly that ... -

Observation of fish behaviour, density and distribution around a surveying vessel by means of a deployable echo sounder system
(ICES CM Documents;1999/J:9, Working paper, 1999)Detailed acoustic observations of fish behaviour, distribution and density in the trawl area are necessary in order to establish quantitative relationships between trawl samples and fish density. Acoustic observation ... -
Observations of abundance, stock composition, body size and food of postsmolts of Atlantic salmon in the NE Atlantic during summer
(ICES CM Documents;1996/M:4, Working paper, 1996)Postsmolt Atlantic salmon were caught during pelagic trawl surveys in the Norwegian Sea in July-August, 1991 and 1995, and off the Hebrides in May-June 1995. Using the swept area technique abundance estimates of postmolts ... -
Operational oceanography of the North Sea/Skagerrak and Norwegian Sea by Ferrbox systems: from one line to a coordinated network of Ferryboxes

Optimum size of sampling unit for estimating the density of marine populations
(ICES CM Documents;1989/D:22, Working paper, 1989)Data from several trawling experiments and from some scallop dredge surveys indicate that, within limits, a srnaller sampling unit can be more effective than a larger unit for marine abundance surveys. Taking into account ... -
Parasitic nematodes in stomachs of grey seals, Halichoerus grypus, and common seals, Phoca vitulina, along the Norwegian coast.
(ICES CM Documents;1984/N:3, Working paper, 1984)The nematode infestation in stomachs of 55 grey and 127 common seals were examined in the period 1976-1980. The seals were caught in Norwegian coastal waters between 62° and 67° North. In 48 adult grey seals the infestation ... -
Pelagic occurrence of Greenland halibut (Reinhardtius hippoglossoides) studied by means of vertical longlines
(ICES CM Documents;2004/K:69, Working paper, 2004)In order to calculate reliable survey indices it’s important to know the dynamics of vertical distribution of a fish species. The vertical distribution of Greenland halibut (Reinhardtius hippogolossoides) cannot be studied ... -
Preliminary report from the sea-going workshop in Norway June 1993 on intercomparison and evaluation of methods for sampling and determination of zooplankton distribution and biomass
(ICES CM Documents;1993/L:45, Working paper, 1993)A sea-going workshop was arranged from 2 to 13 June 1993 in Storfjorden at Møre on the west coast of Norway. The workshop was a two-ship operation involving the Norwegian R/V "Johan Hjort" and the German R/V "A.V. Humboldt". ... -
Prey-specific gastric evacuation of Norwegian spring spawning herring (Clupea harengus)
(ICES CM Documents;2004/P:39, Working paper, 2004)Gastric evacuation rates have earlier mainly been measured based on laboratory experiments. The aim of this study is to obtain information of gastric evacuation rates when the herring are feeding in their natural environment. ... -
