An intership sonar calibration experiment in the Norwegian Sea
(ICES CM Documents;1996/B:22, Working paper, 1996)When migrating in the Norwegian Sea in spring and summertime, the Norwegian spring spawning herring will be surveyed by vessels from four nations. Because the herring may occur in schools close to the surface, use of ... -
Analysis of spatial variability of Georges Bank haddock (Melanogrammus aeglefinus) from trawl survey data using a linear regression model with spatial interaction
(ICES CM Documents;1990/D:36, Working paper, 1990)A regression model with spatially autocorrelated errors is used to test if there is systematic spatial variation across the study area in haddock catch per tow data from the NEFC annual fall survey from 1963 - 1987. A ... -
Arctic intermediate water in the Norwegian Sea
(ICES CM Documents;1986/C:14, Working paper, 1986)Two types of intermediate water propagate into the Norwegian Sea from the Iceland and Greenland seas. North Icelandic Winter water flows along the slope cf the Faroe-Iceland Ridge towards the Faroes . The distribution ... -
Are there potential resources of Iceland scallops (Chlamys islandica) in the Barents Sea ?
(ICES CM Documents;1985/K:43, Working paper, 1985) -
Assessing trawl-survey estimates of frequency distributions
(ICES CM Documents;2000/K:23, Working paper, 2000)Marine trawl surveys catch a cluster of fish at each station and fish caught together tend to have more similar characteristics, such as length, age, stomach contents etc., than those in the entire population. When this ... -
Assessment of potential oil pollution damages on fish resources. Some examples from the area outside mid-Norway
(ICES CM Documents;1987/E:13, Working paper, 1987)Detailed mapping of fish eggs and larvae both in space and time is essential knowledge when realistic assessments of oil pollution damages to the fish resources are established. The text explain with some examples our ... -
Atlanto-scandian herring and capelin working group report [Copenhagen, 28 - 30 October, 1981]
(ICES CM Documents;1982/Assess:2, Working paper, 1982) -
Avoidance reactions of herring to a survey vessel, studied by scanning sonar
(ICES CM Documents;1988/H:46, Working paper, 1988)The behavioural response of a shallow herring layer to a steaming vessel has been studied by the use of a high-resolution scanning sonar technique. When the vessel was completely darkened, no significant reaction important ... -
Barents Sea Ecosystem Resilience under global environmental change 2010-2013
(ICES CM Documents;2010/Q:27, Working paper, 2010) -
Barents Sea King Crab (Paralithodes camtschatica). The transplantation experiments were successfull
(ICES CM Documents;1994/K:12, Working paper, 1994)As a result of the USSR tranplantation experiments, a viable, self-reproducing poulation of king crab, (Paralithodes camtschatica), is now well established in the Barents Sea. Commercial fishing for king crab is prohibited ... -
Behavioural rhythm of cod during migration in the Barents Sea
(ICES CM Documents;2000/K:34, Working paper, 2000)To assess fish abundance by direct methods and to understand and model species interaction, it is important to have proper knowledge about behavioural patterns. Patterns in vertical distribution might strongly affect ... -
Biological reference points for north-east Arctic cod and haddock
(ICES CM Documents;1989/G:29, Working paper, 1989)It has been suggested by ACFM that Fmed might be preferable to Fmax as a biological reference point for the North-East Arctic cod. However, the Fmed level of more than twice Fmax appeared high, and it was known to have ... -
Blue whiting in the Norwegian Sea, spring and summer 1995 and 1996
(ICES CM Documents;1997/CC:15, Working paper, 1997)The Norwegian Sea is an important feeding area for blue whiting in the Northeast Atlantic. The adult blue whiting migrates into the Norwegian Sea after spawning along the continental slope west of The British Isles. A ... -
Bycatch of juvenile fish in the shrimp fishery - management based on bioeconomic criteria
(ICES CM Documents;1994/T:14, Working paper, 1994)The bycatch of juvenile fish can be a major problem in fisheries with small meshed trawls, such as fisheries for shrimp, (Pandalus borealis). A sorting grid that effectively removes most of the undersized fish has been ... -
Can a bioenergetics model explain growth of the northeast Arctic cod?
(ICES CM Documents;1994/G:7, Working paper, 1994)For the period 1984 to 1991, the individual maximum daily consumption in calories (cmax) based on 33000 cod stomach samples is given by the power equation: Cmax = 68.84 · W ^0,934 where W represents the total fish ... -
Changes in abundance and distribution of the Barents Sea long rough dab, hippoglossoides platessoides (Fabricius) during the period 1980- 1992
(ICES CM Documents;1993/G:36, Working paper, 1993)Abundance and biomass of long rough dab in tha Barents Sea and adjacent waters were assessed from bottom trawl survey data from research surveys by Norway and Russia, during the period 1980- 1992. Although there was no ... -
Changes in the Norwegian Sea deep water
(ICES CM Documents;1996/O:11, Working paper, 1996)This paper deals with observed changes in the Norwegian Sea Deep Water (NSDW) after the cessation of bottom water formation in the Greenland Sea. Current measurements indicate that the deep water flow from the Greenland ... -
