Assessing growth of Northeast Arctic cod by a bioenergetics model
(ICES CM Documents;1996/G:16, Working paper, 1996)This paper represents an attempt to elucidate how fish body size differences and metabolic costs alter the relationship between growth and consumption using a bioenergetics model. The results show that the daily growth ... -
Assessing natural mortality of anchovy from surveys' population and biomass estimates
(ICES CM documents;2010/C:12, Working paper, 2010)In ordinary catch at age models, natural mortality conditions and determines the catchabilities at age obtained for the surveys which tune the assessments. For the same reason, inferring the Natural mortality of a fish ... -
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 ... -
Assessment of the North-East Arctic and North Sea Stocks of Saithe Taking Into Account Migration
(ICES CM Documents;1981/G:36, Working paper, 1981)Tagging experiments have shown that there is a substantial migration of young saithe from the Norwegian coast north of 62°N to the North Sea. Assessments of the North-East Arctic and North Sea Stocks of saithe were made ... -
Assessments of the Arcto-Norwegian cod stock : The yield and size of the mature stock versus fishing pattern, fishing effort, natural mortality and mesh size
(ICES CM Documents;1975/F:34, Working paper, 1975) -

Atlanto-scandian herring and capelin working group report [Copenhagen, 28 - 30 October, 1981]
(ICES CM Documents;1982/Assess:2, Working paper, 1982) -
Atlanto-Scandian Herring and Capelin Working Group Report [ICES headquarters, 25 -28 October, 1983]
(ICES CM Documents;1984/Assess:4, Working paper, 1984) -
Automatic recording of fish heart rate on a personal computer
(ICES CM Documents;1988/B:34, Working paper, 1988)From acoustic tags operated into fish in a closed system, the heartbeat signals are sent via underwater telemetry and counted on a personal computer. The computer removes false pulses caused by noise, and calculates the ... -
Automatic species recognition, length measurement and weight determination, using the CatchMeter computer vision system
(ICES CM documents, Working paper, 2006)The collection of biological data on species composition and individual length and weight of specimen has always been an important part of fisheries research. Traditionally, the collected information has been recorded on ... -
The autumn spawning group of herring in the north-eastern North Sea
(ICES CM Documents;1966/H:26, Working paper, 1966) -
Back-calculated length at age in Norwegian spring-spawning herring (Clupea harengus L.) : Estimating the common intercept or origin by tuning back-calculated length frequencies to observed ones
(ICES CM Documents;1996/D:9, Working paper, 1996)In Norwegian spring-spawning herring the common intercept of the back-calculating formula, as estimated by linear regression of the fish-scale relationship, grosssly overestimated the back-calculated length frequencie ... -
Bacterial diseases of eggs and yolk sac larvae of halibut (Hippoglossus hippoglossus L.): Characterization and experimental infection
(ICES CM Documents;1990/F:38, Working paper, 1990)Scanning electron micrographs of halibut eggs which were shown to have an epiflora dominated by a Flexibacter sp., revealed wounds colonized by large amounts of bacteria. The chorion was penetrated in most wounds, and ... -
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 ... -
Bathymetric conformal variography of the spawning stock of Northern blue whiting
(ICES CM Documents;1996/S:46, Working paper, 1996)Bathymetric-based conformal isotropic and anisotropic variograms are defined. These are applied to the spawning stock of northern blue whiting (Micromesistius poutassou) along the slope of the continental shelf west of the ... -
Behaviour of Atlantic salmon (Salmo salar L.) recorded by data storage tags in the NE Atlantic – implications for interception by pelagic trawls
(ICES CM documents, Working paper, 2006)In a project carried out in the Nordic Seas (Northeast Atlantic) in 2002 - 2004, 413 Atlantic salmon (Salmo salar L.) were tagged with data storage tags (DST) either logging temperature and depth (StarOddi, Milli) or ... -
Behaviour of Norwegian spring spawning herring in relation to underwater light
(ICES CM Documents;1988/B:24, Working paper, 1988)The Norwegian coastal purse seiners, with shallow nets, have experienced difficulties in catching the herring due to their natura! behaviour being located too deep during day time and toe scattered during night time. ... -
Bio-physical properties of Norwegian coastal cod eggs
(ICES CM documents;2009/C:11, Working paper, 2009)Vertical distribution of fish eggs and larvae is a key factor for transport and retention of the offspring, and for problems linked to mixing/separation between populations, and hence for mechanism maintaining genetic ... -
